Sending a text message to a user can be accomplished in only a few lines of code: <div class="code"><pre> XMPPConnection connection = <font color="navy"><b>new</b></font> XMPPConnection(<font color="green">"jabber.org"</font>); connection.connect(); connection.login(<font color="green">"mtucker"</font>, <font color="green">"password"</font>); Chat chat = connection.getChatManager().createChat(<font color="green">"jsmith@jivesoftware.com"</font>, new MessageListener() { public void processMessage(Chat chat, Message message) { System.out.println(<font color="green">"Received message: "</font> + message); } }); chat.sendMessage(<font color="green">"Howdy!"</font>); </pre></div> <li>Doesn't force you to code at the packet level, as other libraries do. Smack provides intelligent higher level constructs such as the <tt>Chat</tt> and <tt>Roster</tt> classes, which let you program more efficiently. <li>Does not require that you're familiar with the XMPP XML format, or even that you're familiar with XML. <li>Provides easy machine to machine communication. Smack lets you set any number of properties on each message, including properties that are Java objects. <li>Open Source under the Apache License, which means you can incorporate Smack into your commercial or non-commercial applications. </ul> <p class="subheader"> About XMPP </p> XMPP (eXtensible Messaging and Presence Protocol) is an open protocol standardized by the IETF and supported and extended by the XMPP Standards Foundation ((<a href="http://www.jabber.org">http://www.xmpp.org</a>). <p class="subheader"> How To Use This Documentation </p> This documentation assumes that you're already familiar with the main features of XMPP instant messaging. It's also highly recommended that you open the Javadoc API guide and use that as a reference while reading through this documentation. <br clear="all" /><br><br> <div class="footer"> Copyright © Jive Software 2002-2007 </div> </body> </html>
