+/***
+ * The DatagramSocketClient provides the basic operations that are required
+ * of client objects accessing datagram sockets. It is meant to be
+ * subclassed to avoid having to rewrite the same code over and over again
+ * to open a socket, close a socket, set timeouts, etc. Of special note
+ * is the {@link #setDatagramSocketFactory setDatagramSocketFactory }
+ * method, which allows you to control the type of DatagramSocket the
+ * DatagramSocketClient creates for network communications. This is
+ * especially useful for adding things like proxy support as well as better
+ * support for applets. For
+ * example, you could create a
+ * {@link org.apache.commons.net.DatagramSocketFactory}
+ * that
+ * requests browser security capabilities before creating a socket.
+ * All classes derived from DatagramSocketClient should use the
+ * {@link #_socketFactory_ _socketFactory_ } member variable to
+ * create DatagramSocket instances rather than instantiating
+ * them by directly invoking a constructor. By honoring this contract
+ * you guarantee that a user will always be able to provide his own
+ * Socket implementations by substituting his own SocketFactory.

+ * RCommandClient is very similar to
+ * {@link org.apache.commons.net.bsd.RExecClient},
+ * from which it is derived, and implements the rcmd() facility that
+ * first appeared in 4.2BSD Unix. rcmd() is the facility used by the rsh
+ * (rshell) and other commands to execute a command on another machine
+ * from a trusted host without issuing a password. The trust relationship
+ * between two machines is established by the contents of a machine's
+ * /etc/hosts.equiv file and a user's .rhosts file. These files specify
+ * from which hosts and accounts on those hosts rcmd() requests will be
+ * accepted. The only additional measure for establishing trust is that
+ * all client connections must originate from a port between 512 and 1023.
+ * Consequently, there is an upper limit to the number of rcmd connections
+ * that can be running simultaneously. The required ports are reserved
+ * ports on Unix systems, and can only be bound by a
+ * process running with root permissions (to accomplish this rsh, rlogin,
+ * and related commands usualy have the suid bit set). Therefore, on a
+ * Unix system, you will only be able to successfully use the RCommandClient
+ * class if the process runs as root. However, there is no such restriction
+ * on Windows95 and some other systems. The security risks are obvious.
+ * However, when carefully used, rcmd() can be very useful when used behind
+ * a firewall.
+ * <p>
+ * As with virtually all of the client classes in org.apache.commons.net, this
+ * class derives from SocketClient. But it overrides most of its connection
+ * methods so that the local Socket will originate from an acceptable
+ * rshell port. The way to use RCommandClient is to first connect
+ * to the server, call the {@link #rcommand rcommand() } method,
+ * and then
+ * fetch the connection's input, output, and optionally error streams.
+ * Interaction with the remote command is controlled entirely through the
+ * I/O streams. Once you have finished processing the streams, you should
+ * invoke {@link org.apache.commons.net.bsd.RExecClient#disconnect disconnect() }
+ * to clean up properly.
+ * <p>
+ * By default the standard output and standard error streams of the
+ * remote process are transmitted over the same connection, readable
+ * from the input stream returned by
+ * {@link org.apache.commons.net.bsd.RExecClient#getInputStream getInputStream() }
+ * . However, it is
+ * possible to tell the rshd daemon to return the standard error
+ * stream over a separate connection, readable from the input stream
+ * returned by {@link org.apache.commons.net.bsd.RExecClient#getErrorStream getErrorStream() }
+ * . You
+ * can specify that a separate connection should be created for standard
+ * error by setting the boolean <code> separateErrorStream </code>
+ * parameter of {@link #rcommand rcommand() } to <code> true </code>.
+ * The standard input of the remote process can be written to through
+ * the output stream returned by
+ * {@link org.apache.commons.net.bsd.RExecClient#getOutputStream getOutputStream() }
+ * .

+ * RLoginClient is very similar to

+ * from which it is derived, and uses the rcmd() facility implemented
+ * in RCommandClient to implement the functionality of the rlogin command that
+ * first appeared in 4.2BSD Unix. rlogin is a command used to login to
+ * a remote machine from a trusted host, sometimes without issuing a
+ * password. The trust relationship is the same as described in
+ * the documentation for
+ * {@link org.apache.commons.net.bsd.RCommandClient}.
+ * <p>
+ * As with virtually all of the client classes in org.apache.commons.net, this
+ * class derives from SocketClient. But it relies on the connection
+ * methods defined in RcommandClient which ensure that the local Socket
+ * will originate from an acceptable rshell port. The way to use
+ * RLoginClient is to first connect
+ * to the server, call the {@link #rlogin rlogin() } method,
+ * and then
+ * fetch the connection's input and output streams.
+ * Interaction with the remote command is controlled entirely through the
+ * I/O streams. Once you have finished processing the streams, you should
+ * invoke {@link org.apache.commons.net.bsd.RExecClient#disconnect disconnect() }
+ * to clean up properly.
+ * <p>
+ * The standard output and standard error streams of the
+ * remote process are transmitted over the same connection, readable
+ * from the input stream returned by
+ * {@link org.apache.commons.net.bsd.RExecClient#getInputStream getInputStream() }
+ * . Unlike RExecClient and RCommandClient, it is
+ * not possible to tell the rlogind daemon to return the standard error
+ * stream over a separate connection.
+ * {@link org.apache.commons.net.bsd.RExecClient#getErrorStream getErrorStream() }
+ * will always return null.
+ * The standard input of the remote process can be written to through
+ * the output stream returned by

+ * FTP provides the basic the functionality necessary to implement your
+ * own FTP client. It extends org.apache.commons.net.SocketClient since
+ * extending TelnetClient was causing unwanted behavior (like connections
+ * that did not time out properly).
+ * <p>
+ * To derive the full benefits of the FTP class requires some knowledge
+ * of the FTP protocol defined in RFC 959. However, there is no reason
+ * why you should have to use the FTP class. The
+ * {@link org.apache.commons.net.ftp.FTPClient} class,
+ * derived from FTP,
+ * implements all the functionality required of an FTP client. The
+ * FTP class is made public to provide access to various FTP constants
+ * and to make it easier for adventurous programmers (or those with
+ * special needs) to interact with the FTP protocol and implement their
+ * own clients. A set of methods with names corresponding to the FTP
+ * command names are provided to facilitate this interaction.
+ * <p>
+ * You should keep in mind that the FTP server may choose to prematurely
+ * close a connection if the client has been idle for longer than a
+ * given time period (usually 900 seconds). The FTP class will detect a
+ * premature FTP server connection closing when it receives a
+ * {@link org.apache.commons.net.ftp.FTPReply#SERVICE_NOT_AVAILABLE FTPReply.SERVICE_NOT_AVAILABLE }
+ * response to a command.
+ * When that occurs, the FTP class method encountering that reply will throw
+ * an {@link org.apache.commons.net.ftp.FTPConnectionClosedException}
+ * . <code>FTPConectionClosedException</code>
+ * is a subclass of <code> IOException </code> and therefore need not be
+ * caught separately, but if you are going to catch it separately, its
+ * catch block must appear before the more general <code> IOException </code>
+ * catch block. When you encounter an
+ * {@link org.apache.commons.net.ftp.FTPConnectionClosedException}
+ * , you must disconnect the connection with
+ * {@link #disconnect disconnect() } to properly clean up the
+ * system resources used by FTP. Before disconnecting, you may check the
+ * last reply code and text with
+ * {@link #getReplyCode getReplyCode },
+ * {@link #getReplyString getReplyString },
+ * and {@link #getReplyStrings getReplyStrings}.
+ * You may avoid server disconnections while the client is idle by
+ * periodicaly sending NOOP commands to the server.
+ * <p>
+ * Rather than list it separately for each method, we mention here that
+ * every method communicating with the server and throwing an IOException
+ * can also throw a
+ * {@link org.apache.commons.net.MalformedServerReplyException}
+ * , which is a subclass
+ * of IOException. A MalformedServerReplyException will be thrown when
+ * the reply received from the server deviates enough from the protocol
+ * specification that it cannot be interpreted in a useful manner despite
+ * attempts to be as lenient as possible.

+/***
+ * FTPClient encapsulates all the functionality necessary to store and
+ * retrieve files from an FTP server. This class takes care of all
+ * low level details of interacting with an FTP server and provides
+ * a convenient higher level interface. As with all classes derived
+ * from {@link org.apache.commons.net.SocketClient},
+ * you must first connect to the server with
+ * {@link org.apache.commons.net.SocketClient#connect connect }
+ * before doing anything, and finally
+ * {@link org.apache.commons.net.SocketClient#disconnect disconnect }
+ * after you're completely finished interacting with the server.
+ * Then you need to check the FTP reply code to see if the connection
+ * was successful. For example:
+ * <pre>
+ * boolean error = false;
+ * try {
+ * int reply;
+ * ftp.connect("ftp.foobar.com");
+ * System.out.println("Connected to " + server + ".");
+ * System.out.print(ftp.getReplyString());
+ *
+ * // After connection attempt, you should check the reply code to verify
+ * // success.
+ * reply = ftp.getReplyCode();
+ *
+ * if(!FTPReply.isPositiveCompletion(reply)) {
+ * ftp.disconnect();
+ * System.err.println("FTP server refused connection.");
+ * System.exit(1);
+ * }
+ * ... // transfer files
+ * ftp.logout();
+ * } catch(IOException e) {
+ * error = true;
+ * e.printStackTrace();
+ * } finally {
+ * if(ftp.isConnected()) {
+ * try {
+ * ftp.disconnect();
+ * } catch(IOException ioe) {
+ * // do nothing
+ * }
+ * }
+ * System.exit(error ? 1 : 0);
+ * }
+ * </pre>
+ * <p>
+ * Immediately after connecting is the only real time you need to check the
+ * reply code (because connect is of type void). The convention for all the
+ * FTP command methods in FTPClient is such that they either return a
+ * boolean value or some other value.
+ * The boolean methods return true on a successful completion reply from
+ * the FTP server and false on a reply resulting in an error condition or
+ * failure. The methods returning a value other than boolean return a value
+ * containing the higher level data produced by the FTP command, or null if a
+ * reply resulted in an error condition or failure. If you want to access
+ * the exact FTP reply code causing a success or failure, you must call
+ * {@link org.apache.commons.net.ftp.FTP#getReplyCode getReplyCode } after
+ * a success or failure.
+ * <p>
+ * The default settings for FTPClient are for it to use
+ * <code> FTP.ASCII_FILE_TYPE </code>,
+ * <code> FTP.NON_PRINT_TEXT_FORMAT </code>,
+ * <code> FTP.STREAM_TRANSFER_MODE </code>, and
+ * <code> FTP.FILE_STRUCTURE </code>. The only file types directly supported
+ * are <code> FTP.ASCII_FILE_TYPE </code> and
+ * <code> FTP.BINARY_FILE_TYPE </code>. Because there are at least 4
+ * different EBCDIC encodings, we have opted not to provide direct support
+ * for EBCDIC. To transfer EBCDIC and other unsupported file types you
+ * must create your own filter InputStreams and OutputStreams and wrap
+ * them around the streams returned or required by the FTPClient methods.
+ * FTPClient uses the {@link ToNetASCIIOutputStream NetASCII}
+ * filter streams to provide transparent handling of ASCII files. We will
+ * consider incorporating EBCDIC support if there is enough demand.
+ * <p>
+ * <code> FTP.NON_PRINT_TEXT_FORMAT </code>,
+ * <code> FTP.STREAM_TRANSFER_MODE </code>, and
+ * <code> FTP.FILE_STRUCTURE </code> are the only supported formats,
+ * transfer modes, and file structures.
+ * <p>
+ * Because the handling of sockets on different platforms can differ
+ * significantly, the FTPClient automatically issues a new PORT command
+ * prior to every transfer requiring that the server connect to the client's
+ * data port. This ensures identical problem-free behavior on Windows, Unix,
+ * and Macintosh platforms. Additionally, it relieves programmers from
+ * having to issue the PORT command themselves and dealing with platform
+ * dependent issues.
+ * <p>
+ * Additionally, for security purposes, all data connections to the
+ * client are verified to ensure that they originated from the intended
+ * party (host and port). If a data connection is initiated by an unexpected
+ * party, the command will close the socket and throw an IOException. You
+ * may disable this behavior with
+ * {@link #setRemoteVerificationEnabled setRemoteVerificationEnabled()}.
+ * <p>
+ * You should keep in mind that the FTP server may choose to prematurely
+ * close a connection if the client has been idle for longer than a
+ * given time period (usually 900 seconds). The FTPClient class will detect a
+ * premature FTP server connection closing when it receives a
+ * {@link org.apache.commons.net.ftp.FTPReply#SERVICE_NOT_AVAILABLE FTPReply.SERVICE_NOT_AVAILABLE }
+ * response to a command.
+ * When that occurs, the FTP class method encountering that reply will throw
+ * an {@link org.apache.commons.net.ftp.FTPConnectionClosedException}
+ * .
+ * <code>FTPConnectionClosedException</code>
+ * is a subclass of <code> IOException </code> and therefore need not be
+ * caught separately, but if you are going to catch it separately, its
+ * catch block must appear before the more general <code> IOException </code>
+ * catch block. When you encounter an
+ * {@link org.apache.commons.net.ftp.FTPConnectionClosedException}
+ * , you must disconnect the connection with
+ * {@link #disconnect disconnect() } to properly clean up the
+ * system resources used by FTPClient. Before disconnecting, you may check the
+ * last reply code and text with
+ * {@link org.apache.commons.net.ftp.FTP#getReplyCode getReplyCode },
+ * {@link org.apache.commons.net.ftp.FTP#getReplyString getReplyString },
+ * and
+ * {@link org.apache.commons.net.ftp.FTP#getReplyStrings getReplyStrings}.
+ * You may avoid server disconnections while the client is idle by
+ * periodicaly sending NOOP commands to the server.
+ * <p>
+ * Rather than list it separately for each method, we mention here that
+ * every method communicating with the server and throwing an IOException
+ * can also throw a
+ * {@link org.apache.commons.net.MalformedServerReplyException}
+ * , which is a subclass
+ * of IOException. A MalformedServerReplyException will be thrown when
+ * the reply received from the server deviates enough from the protocol
+ * specification that it cannot be interpreted in a useful manner despite
+ * attempts to be as lenient as possible.
+ * <p>
+ * Listing API Examples
+ * Both paged and unpaged examples of directory listings are available,
+ * as follows:
+ * <p>
+ * Unpaged (whole list) access, using a parser accessible by auto-detect:
+ * <pre>
+ * FTPClient f=FTPClient();
+ * f.connect(server);
+ * f.login(username, password);
+ * FTPFile[] files = listFiles(directory);
+ * </pre>
+ * <p>
+ * Paged access, using a parser not accessible by auto-detect. The class
+ * defined in the first parameter of initateListParsing should be derived
+ * from org.apache.commons.net.FTPFileEntryParser:
+ * <pre>
+ * FTPClient f=FTPClient();
+ * f.connect(server);
+ * f.login(username, password);
+ * FTPListParseEngine engine =
+ * f.initiateListParsing("com.whatever.YourOwnParser", directory);
+ *
+ * while (engine.hasNext()) {
+ * FTPFile[] files = engine.getNext(25); // "page size" you want
+ * //do whatever you want with these files, display them, etc.
+ * //expensive FTPFile objects not created until needed.
+ * }
+ * </pre>
+ * <p>
+ * Paged access, using a parser accessible by auto-detect:
+ * <pre>
+ * FTPClient f=FTPClient();
+ * f.connect(server);
+ * f.login(username, password);
+ * FTPListParseEngine engine = f.initiateListParsing(directory);
+ *
+ * while (engine.hasNext()) {
+ * FTPFile[] files = engine.getNext(25); // "page size" you want
+ * //do whatever you want with these files, display them, etc.
+ * //expensive FTPFile objects not created until needed.
+ * }
+ * </pre>
+ * <p>
+ * For examples of using FTPClient on servers whose directory listings
+ * <ul>
+ * <li>use languages other than English</li>
+ * <li>use date formats other than the American English "standard" <code>MM d yyyy</code></li>
+ * <li>are in different timezones and you need accurate timestamps for dependency checking
+ * as in Ant</li>

+/**
+ * <p>
+ * This class implements an alternate means of configuring the
+ * {@link org.apache.commons.net.ftp.FTPClient FTPClient} object and
+ * also subordinate objects which it uses. Any class implementing the
+ * {@link org.apache.commons.net.ftp.Configurable Configurable }
+ * interface can be configured by this object.
+ * </p><p>
+ * In particular this class was designed primarily to support configuration
+ * of FTP servers which express file timestamps in formats and languages
+ * other than those for the US locale, which although it is the most common
+ * is not universal. Unfortunately, nothing in the FTP spec allows this to
+ * be determined in an automated way, so manual configuration such as this
+ * is necessary.
+ * </p><p>
+ * This functionality was designed to allow existing clients to work exactly
+ * as before without requiring use of this component. This component should
+ * only need to be explicitly invoked by the user of this package for problem
+ * cases that previous implementations could not solve.
+ * </p>
+ * <h3>Examples of use of FTPClientConfig</h3>
+ * Use cases:
+ * You are trying to access a server that
+ * <ul>
+ * <li>lists files with timestamps that use month names in languages other
+ * than English</li>
+ * <li>lists files with timestamps that use date formats other
+ * than the American English "standard" <code>MM dd yyyy</code></li>
+ * <li>is in different timezone and you need accurate timestamps for
+ * dependency checking as in Ant</li>
+ * </ul>
+ * <p>
+ * Unpaged (whole list) access on a UNIX server that uses French month names
+ * but uses the "standard" <code>MMM d yyyy</code> date formatting
+ * <pre>
+ * FTPClient f=FTPClient();
+ * FTPClientConfig conf = new FTPClientConfig(FTPClientConfig.SYST_UNIX);
+ * conf.setServerLanguageCode("fr");
+ * f.configure(conf);
+ * f.connect(server);
+ * f.login(username, password);
+ * FTPFile[] files = listFiles(directory);
+ * </pre>
+ * </p>
+ * <p>
+ * Paged access on a UNIX server that uses Danish month names
+ * and "European" date formatting in Denmark's time zone, when you
+ * are in some other time zone.
+ * <pre>
+ * FTPClient f=FTPClient();
+ * FTPClientConfig conf = new FTPClientConfig(FTPClientConfig.SYST_UNIX);
+ * conf.setServerLanguageCode("da");
+ * conf.setDefaultDateFormat("d MMM yyyy");
+ * conf.setRecentDateFormat("d MMM HH:mm");
+ * conf.setTimeZoneId("Europe/Copenhagen");
+ * f.configure(conf);
+ * f.connect(server);
+ * f.login(username, password);
+ * FTPListParseEngine engine =
+ * f.initiateListParsing("com.whatever.YourOwnParser", directory);
+ *
+ * while (engine.hasNext()) {
+ * FTPFile[] files = engine.getNext(25); // "page size" you want
+ * //do whatever you want with these files, display them, etc.
+ * //expensive FTPFile objects not created until needed.
+ * }
+ * </pre>
+ * </p>
+ * <p>
+ * Unpaged (whole list) access on a VMS server that uses month names
+ * in a language not {@link #getSupportedLanguageCodes() supported} by the system.
+ * but uses the "standard" <code>MMM d yyyy</code> date formatting
+ * <pre>
+ * FTPClient f=FTPClient();
+ * FTPClientConfig conf = new FTPClientConfig(FTPClientConfig.SYST_VMS);
+ * conf.setShortMonthNames(

+ * FTPFile[] files = listFiles(directory);
+ * </pre>
+ * </p>
+ * <p>
+ * Unpaged (whole list) access on a Windows-NT server in a different time zone.
+ * (Note, since the NT Format uses numeric date formatting, language issues
+ * are irrelevant here).
+ * <pre>
+ * FTPClient f=FTPClient();
+ * FTPClientConfig conf = new FTPClientConfig(FTPClientConfig.SYST_NT);
+ * conf.setTimeZoneId("America/Denver");
+ * f.configure(conf);

+/**
+ * FTPFileEntryParser defines the interface for parsing a single FTP file
+ * listing and converting that information into an
+ * {@link org.apache.commons.net.ftp.FTPFile} instance.
+ * Sometimes you will want to parse unusual listing formats, in which
+ * case you would create your own implementation of FTPFileEntryParser and
+ * if necessary, subclass FTPFile.
+ * <p>
+ * Here are some examples showing how to use one of the classes that
+ * implement this interface.
+ * <p>
+ * The first example shows how to get an <b>iterable</b> list of files in which the
+ * more expensive <code>FTPFile</code> objects are not created until needed. This
+ * is suitable for paged displays. It requires that a parser object be created
+ * beforehand: <code>parser</code> is an object (in the package
+ * <code>org.apache.commons.net.ftp.parser</code>)
+ * implementing this inteface.
+ *
+ * <pre>
+ * FTPClient f=FTPClient();
+ * f.connect(server);
+ * f.login(username, password);
+ * FTPFileList list = f.createFileList(directory, parser);
+ * FTPFileIterator iter = list.iterator();
+ *
+ * while (iter.hasNext()) {
+ * FTPFile[] files = iter.getNext(25); // "page size" you want
+ * //do whatever you want with these files, display them, etc.
+ * //expensive FTPFile objects not created until needed.
+ * }
+ * </pre>
+ *
+ * The second example uses the revised <code>FTPClient.listFiles()</code>
+ * API to pull the whole list from the subfolder <code>subfolder</code> in
+ * one call, attempting to automatically detect the parser type. This
+ * method, without a parserKey parameter, indicates that autodection should
+ * be used.
+ *
+ * <pre>
+ * FTPClient f=FTPClient();
+ * f.connect(server);
+ * f.login(username, password);
+ * FTPFile[] files = f.listFiles("subfolder");
+ * </pre>
+ *
+ * The third example uses the revised <code>FTPClient.listFiles()</code>>
+ * API to pull the whole list from the current working directory in one call,
+ * but specifying by classname the parser to be used. For this particular
+ * parser class, this approach is necessary since there is no way to
+ * autodetect this server type.
+ *
+ * <pre>
+ * FTPClient f=FTPClient();
+ * f.connect(server);
+ * f.login(username, password);
+ * FTPFile[] files = f.listFiles(
+ * "org.apache.commons.net.ftp.parser.EnterpriseUnixFTPFileEntryParser",
+ * ".");
+ * </pre>
+ *
+ * The fourth example uses the revised <code>FTPClient.listFiles()</code>
+ * API to pull a single file listing in an arbitrary directory in one call,
+ * specifying by KEY the parser to be used, in this case, VMS.
+ *
+ * <pre>
+ * FTPClient f=FTPClient();
+ * f.connect(server);
+ * f.login(username, password);
+ * FTPFile[] files = f.listFiles("VMS", "subfolder/foo.java");

+/**
+ * This class handles the entire process of parsing a listing of
+ * file entries from the server.
+ * <p>
+ * This object defines a two-part parsing mechanism.
+ * <p>
+ * The first part is comprised of reading the raw input into an internal
+ * list of strings. Every item in this list corresponds to an actual
+ * file. All extraneous matter emitted by the server will have been
+ * removed by the end of this phase. This is accomplished in conjunction
+ * with the FTPFileEntryParser associated with this engine, by calling
+ * its methods <code>readNextEntry()</code> - which handles the issue of
+ * what delimits one entry from another, usually but not always a line
+ * feed and <code>preParse()</code> - which handles removal of
+ * extraneous matter such as the preliminary lines of a listing, removal
+ * of duplicates on versioning systems, etc.
+ * <p>
+ * The second part is composed of the actual parsing, again in conjunction
+ * with the particular parser used by this engine. This is controlled
+ * by an iterator over the internal list of strings. This may be done
+ * either in block mode, by calling the <code>getNext()</code> and
+ * <code>getPrevious()</code> methods to provide "paged" output of less
+ * than the whole list at one time, or by calling the
+ * <code>getFiles()</code> method to return the entire list.
+ * <p>
+ * Examples:
+ * <p>
+ * Paged access:
+ * <pre>
+ * FTPClient f=FTPClient();
+ * f.connect(server);
+ * f.login(username, password);
+ * FTPListParseEngine engine = f.initiateListParsing(directory);
+ *
+ * while (engine.hasNext()) {
+ * FTPFile[] files = engine.getNext(25); // "page size" you want
+ * //do whatever you want with these files, display them, etc.
+ * //expensive FTPFile objects not created until needed.
+ * }
+ * </pre>
+ * <p>
+ * For unpaged access, simply use FTPClient.listFiles(). That method
+ * uses this class transparently.

+ * Very brief and incomplete description of the zOS/MVS-filesystem. (Note:
+ * "zOS" is the operating system on the mainframe, and is the new name for
+ * MVS)
+ *
+ * The filesystem on the mainframe does not have hierarchal structure as for
+ * example the unix filesystem. For a more comprehensive description, please
+ * refer to the IBM manuals
+ *
+ * @LINK:
+ * http://publibfp.boulder.ibm.com/cgi-bin/bookmgr/BOOKS/dgt2d440/CONTENTS
+ *
+ *
+ * Dataset names =============
+ *
+ * A dataset name consist of a number of qualifiers separated by '.', each
+ * qualifier can be at most 8 characters, and the total length of a dataset
+ * can be max 44 characters including the dots.
+ *
+ *
+ * Dataset organisation ====================
+ *
+ * A dataset represents a piece of storage allocated on one or more disks.
+ * The structure of the storage is described with the field dataset
+ * organinsation (DSORG). There are a number of dataset organisations, but
+ * only two are usable for FTP transfer.
+ *
+ * DSORG: PS: sequential, or flat file PO: partitioned dataset PO-E:
+ * extended partitioned dataset
+ *
+ * The PS file is just a flat file, as you would find it on the unix file
+ * system.
+ *
+ * The PO and PO-E files, can be compared to a single level directory
+ * structure. A PO file consist of a number of dataset members, or files if
+ * you will. It is possible to CD into the file, and to retrieve the
+ * individual members.
+ *
+ *
+ * Dataset record format =====================
+ *
+ * The physical layout of the dataset is described on the dataset itself.
+ * There are a number of record formats (RECFM), but just a few is relavant
+ * for the FTP transfer.
+ *
+ * Any one beginning with either F or V can safely used by FTP transfer. All
+ * others should only be used with great care, so this version will just
+ * ignore the other record formats. F means a fixed number of records per
+ * allocated storage, and V means a variable number of records.
+ *
+ *
+ * Other notes ===========
+ *
+ * The file system supports automatically backup and retrieval of datasets.
+ * If a file is backed up, the ftp LIST command will return: ARCIVE Not
+ * Direct Access Device KJ.IOP998.ERROR.PL.UNITTEST
+ *
+ *
+ * Implementation notes ====================
+ *
+ * Only datasets that have dsorg PS, PO or PO-E and have recfm beginning
+ * with F or V, is fully parsed.
+ *
+ * The following fields in FTPFile is used: FTPFile.Rawlisting: Always set.
+ * FTPFile.Type: DIRECTORY_TYPE or FILE_TYPE or UNKNOWN FTPFile.Name: name
+ * FTPFile.Timestamp: change time or null
+ *
+ *
+ *
+ * Additional information ======================
+ *
+ * The MVS ftp server supports a number of features via the FTP interface.
+ * The features are controlled with the FTP command quote site filetype=<SEQ|JES|DB2>
+ * SEQ is the default and used for normal file transfer JES is used to
+ * interact with the Job Entry Subsystem (JES) similar to a job scheduler
+ * DB2 is used to interact with a DB2 subsystem
+ *
+ * This parser supports SEQ and JES.

+ * The NNTP class is not meant to be used by itself and is provided
+ * only so that you may easily implement your own NNTP client if
+ * you so desire. If you have no need to perform your own implementation,
+ * you should use {@link org.apache.commons.net.nntp.NNTPClient}.
+ * The NNTP class is made public to provide access to various NNTP constants
+ * and to make it easier for adventurous programmers (or those with special
+ * needs) to interact with the NNTP protocol and implement their own clients.
+ * A set of methods with names corresponding to the NNTP command names are
+ * provided to facilitate this interaction.
+ * <p>
+ * You should keep in mind that the NNTP server may choose to prematurely
+ * close a connection if the client has been idle for longer than a
+ * given time period or if the server is being shutdown by the operator or
+ * some other reason. The NNTP class will detect a
+ * premature NNTP server connection closing when it receives a
+ * {@link org.apache.commons.net.nntp.NNTPReply#SERVICE_DISCONTINUED NNTPReply.SERVICE_DISCONTINUED }
+ * response to a command.
+ * When that occurs, the NNTP class method encountering that reply will throw
+ * an {@link org.apache.commons.net.nntp.NNTPConnectionClosedException}
+ * .
+ * <code>NNTPConectionClosedException</code>
+ * is a subclass of <code> IOException </code> and therefore need not be
+ * caught separately, but if you are going to catch it separately, its
+ * catch block must appear before the more general <code> IOException </code>
+ * catch block. When you encounter an
+ * {@link org.apache.commons.net.nntp.NNTPConnectionClosedException}
+ * , you must disconnect the connection with
+ * {@link #disconnect disconnect() } to properly clean up the
+ * system resources used by NNTP. Before disconnecting, you may check the
+ * last reply code and text with
+ * {@link #getReplyCode getReplyCode } and
+ * {@link #getReplyString getReplyString }.
+ * <p>
+ * Rather than list it separately for each method, we mention here that
+ * every method communicating with the server and throwing an IOException
+ * can also throw a
+ * {@link org.apache.commons.net.MalformedServerReplyException}
+ * , which is a subclass
+ * of IOException. A MalformedServerReplyException will be thrown when
+ * the reply received from the server deviates enough from the protocol
+ * specification that it cannot be interpreted in a useful manner despite
+ * attempts to be as lenient as possible.

+ * NNTPClient encapsulates all the functionality necessary to post and
+ * retrieve articles from an NNTP server. As with all classes derived
+ * from {@link org.apache.commons.net.SocketClient},
+ * you must first connect to the server with
+ * {@link org.apache.commons.net.SocketClient#connect connect }
+ * before doing anything, and finally
+ * {@link org.apache.commons.net.nntp.NNTP#disconnect disconnect() }
+ * after you're completely finished interacting with the server.
+ * Remember that the
+ * {@link org.apache.commons.net.nntp.NNTP#isAllowedToPost isAllowedToPost()}
+ * method is defined in
+ * {@link org.apache.commons.net.nntp.NNTP}.
+ * <p>
+ * You should keep in mind that the NNTP server may choose to prematurely
+ * close a connection if the client has been idle for longer than a
+ * given time period or if the server is being shutdown by the operator or
+ * some other reason. The NNTP class will detect a
+ * premature NNTP server connection closing when it receives a
+ * {@link org.apache.commons.net.nntp.NNTPReply#SERVICE_DISCONTINUED NNTPReply.SERVICE_DISCONTINUED }
+ * response to a command.
+ * When that occurs, the NNTP class method encountering that reply will throw
+ * an {@link org.apache.commons.net.nntp.NNTPConnectionClosedException}
+ * .
+ * <code>NNTPConectionClosedException</code>
+ * is a subclass of <code> IOException </code> and therefore need not be
+ * caught separately, but if you are going to catch it separately, its
+ * catch block must appear before the more general <code> IOException </code>
+ * catch block. When you encounter an
+ * {@link org.apache.commons.net.nntp.NNTPConnectionClosedException}
+ * , you must disconnect the connection with
+ * {@link org.apache.commons.net.nntp.NNTP#disconnect disconnect() }
+ * to properly clean up the
+ * system resources used by NNTP. Before disconnecting, you may check the
+ * last reply code and text with
+ * {@link org.apache.commons.net.nntp.NNTP#getReplyCode getReplyCode } and
+ * {@link org.apache.commons.net.nntp.NNTP#getReplyString getReplyString }.
+ * <p>
+ * Rather than list it separately for each method, we mention here that
+ * every method communicating with the server and throwing an IOException
+ * can also throw a
+ * {@link org.apache.commons.net.MalformedServerReplyException}
+ * , which is a subclass
+ * of IOException. A MalformedServerReplyException will be thrown when
+ * the reply received from the server deviates enough from the protocol
+ * specification that it cannot be interpreted in a useful manner despite
+ * attempts to be as lenient as possible.

+ * SMTP provides the basic the functionality necessary to implement your
+ * own SMTP client. To derive the full benefits of the SMTP class requires
+ * some knowledge of the FTP protocol defined in RFC 821. However, there
+ * is no reason why you should have to use the SMTP class. The
+ * {@link org.apache.commons.net.smtp.SMTPClient} class,
+ * derived from SMTP,
+ * implements all the functionality required of an SMTP client. The
+ * SMTP class is made public to provide access to various SMTP constants
+ * and to make it easier for adventurous programmers (or those with
+ * special needs) to interact with the SMTP protocol and implement their
+ * own clients. A set of methods with names corresponding to the SMTP
+ * command names are provided to facilitate this interaction.
+ * <p>
+ * You should keep in mind that the SMTP server may choose to prematurely
+ * close a connection for various reasons. The SMTP class will detect a
+ * premature SMTP server connection closing when it receives a
+ * {@link org.apache.commons.net.smtp.SMTPReply#SERVICE_NOT_AVAILABLE SMTPReply.SERVICE_NOT_AVAILABLE }
+ * response to a command.
+ * When that occurs, the SMTP class method encountering that reply will throw
+ * an {@link org.apache.commons.net.smtp.SMTPConnectionClosedException}
+ * .
+ * <code>SMTPConectionClosedException</code>
+ * is a subclass of <code> IOException </code> and therefore need not be
+ * caught separately, but if you are going to catch it separately, its
+ * catch block must appear before the more general <code> IOException </code>
+ * catch block. When you encounter an
+ * {@link org.apache.commons.net.smtp.SMTPConnectionClosedException}
+ * , you must disconnect the connection with
+ * {@link org.apache.commons.net.SocketClient#disconnect disconnect() }
+ * to properly clean up the system resources used by SMTP. Before
+ * disconnecting, you may check the
+ * last reply code and text with
+ * {@link #getReplyCode getReplyCode },
+ * {@link #getReplyString getReplyString },
+ * and {@link #getReplyStrings getReplyStrings}.
+ * <p>
+ * Rather than list it separately for each method, we mention here that
+ * every method communicating with the server and throwing an IOException
+ * can also throw a
+ * {@link org.apache.commons.net.MalformedServerReplyException}
+ * , which is a subclass
+ * of IOException. A MalformedServerReplyException will be thrown when
+ * the reply received from the server deviates enough from the protocol
+ * specification that it cannot be interpreted in a useful manner despite
+ * attempts to be as lenient as possible.

+/***
+ * SMTPClient encapsulates all the functionality necessary to send files
+ * through an SMTP server. This class takes care of all
+ * low level details of interacting with an SMTP server and provides
+ * a convenient higher level interface. As with all classes derived
+ * from {@link org.apache.commons.net.SocketClient},
+ * you must first connect to the server with
+ * {@link org.apache.commons.net.SocketClient#connect connect }
+ * before doing anything, and finally
+ * {@link org.apache.commons.net.SocketClient#disconnect disconnect }
+ * after you're completely finished interacting with the server.
+ * Then you need to check the SMTP reply code to see if the connection
+ * was successful. For example:
+ * <pre>
+ * try {
+ * int reply;
+ * client.connect("mail.foobar.com");
+ * System.out.print(client.getReplyString());
+ *
+ * // After connection attempt, you should check the reply code to verify
+ * // success.
+ * reply = client.getReplyCode();
+ *
+ * if(!SMTPReply.isPositiveCompletion(reply)) {
+ * client.disconnect();
+ * System.err.println("SMTP server refused connection.");
+ * System.exit(1);
+ * }
+ *
+ * // Do useful stuff here.
+ * ...
+ * } catch(IOException e) {
+ * if(client.isConnected()) {
+ * try {
+ * client.disconnect();
+ * } catch(IOException f) {
+ * // do nothing
+ * }
+ * }
+ * System.err.println("Could not connect to server.");
+ * e.printStackTrace();
+ * System.exit(1);
+ * }
+ * </pre>
+ * <p>
+ * Immediately after connecting is the only real time you need to check the
+ * reply code (because connect is of type void). The convention for all the
+ * SMTP command methods in SMTPClient is such that they either return a
+ * boolean value or some other value.
+ * The boolean methods return true on a successful completion reply from
+ * the SMTP server and false on a reply resulting in an error condition or
+ * failure. The methods returning a value other than boolean return a value
+ * containing the higher level data produced by the SMTP command, or null if a
+ * reply resulted in an error condition or failure. If you want to access
+ * the exact SMTP reply code causing a success or failure, you must call
+ * {@link org.apache.commons.net.smtp.SMTP#getReplyCode getReplyCode } after
+ * a success or failure.
+ * <p>
+ * You should keep in mind that the SMTP server may choose to prematurely
+ * close a connection for various reasons. The SMTPClient class will detect a
+ * premature SMTP server connection closing when it receives a
+ * {@link org.apache.commons.net.smtp.SMTPReply#SERVICE_NOT_AVAILABLE SMTPReply.SERVICE_NOT_AVAILABLE }
+ * response to a command.
+ * When that occurs, the method encountering that reply will throw
+ * an {@link org.apache.commons.net.smtp.SMTPConnectionClosedException}
+ * .
+ * <code>SMTPConectionClosedException</code>
+ * is a subclass of <code> IOException </code> and therefore need not be
+ * caught separately, but if you are going to catch it separately, its
+ * catch block must appear before the more general <code> IOException </code>
+ * catch block. When you encounter an
+ * {@link org.apache.commons.net.smtp.SMTPConnectionClosedException}
+ * , you must disconnect the connection with
+ * {@link #disconnect disconnect() } to properly clean up the
+ * system resources used by SMTPClient. Before disconnecting, you may check
+ * the last reply code and text with
+ * {@link org.apache.commons.net.smtp.SMTP#getReplyCode getReplyCode },
+ * {@link org.apache.commons.net.smtp.SMTP#getReplyString getReplyString },
+ * and
+ * {@link org.apache.commons.net.smtp.SMTP#getReplyStrings getReplyStrings}.
+ * <p>
+ * Rather than list it separately for each method, we mention here that
+ * every method communicating with the server and throwing an IOException
+ * can also throw a
+ * {@link org.apache.commons.net.MalformedServerReplyException}
+ * , which is a subclass
+ * of IOException. A MalformedServerReplyException will be thrown when
+ * the reply received from the server deviates enough from the protocol
+ * specification that it cannot be interpreted in a useful manner despite
+ * attempts to be as lenient as possible.
