This document will introduce you to the Smack API and provide an overview of
|

important classes and concepts.

Requirements
|
|
</p>
|
|
|
|
The only requirement for Smack is JDK 1.2 or later. An XML parser is embedded in the smack.jar
|
|
file and no other third party libraries are required.

Establishing a Connection
|
|
</p>
|
|
|
|
The <tt>XMPPConnection</tt> class is used to create a connection to an
|
|
XMPP server. To create an SSL connection, use the SSLXMPPConnection class.
|
|
Below are code examples for making a connection:<p>
|
|
|
|
<div class="code">
|
|
<pre>
|
|
<font color="gray"><i>// Create a connection to the jabber.org server.</i></font>
|
|
XMPPConnection conn1 = <font color="navy"><b>new</b></font> XMPPConnection(<font color="green">"jabber.org"</font>);
|
|
|
|
<font color="gray"><i>// Create a connection to the jabber.org server on a specific port.</i></font>
|
|
XMPPConnection conn2 = <font color="navy"><b>new</b></font> XMPPConnection(<font color="green">"jabber.org"</font>, 5222);
|
|
|
|
<font color="gray"><i>// Create an SSL connection to jabber.org.</i></font>
|
|
XMPPConnection connection = <font color="navy"><b>new</b></font> SSLXMPPConnection(<font color="green">"jabber.org"</font>);
|
|
</pre></div>
|
|
|
|
<p>Once you've created a connection, you should login using a username and password
|
|
with the <tt>XMPPConnection.login(String username, String password)</tt> method.
|
|
Once you've logged in, you can being chatting with other users by creating
|
|
new <tt>Chat</tt> or <tt>GroupChat</tt> objects.

Packets, the PacketReader, and the PacketWriter
|
|
</p>
|
|
|
|
Each message to the XMPP server from a client is called a packet and is
|
|
sent as XML. The <tt>org.jivesoftware.smack.packet</tt> package contains
|
|
classes that encapsulate the different packet types allowed by XMPP (message,
|
|
presence, and IQ). Classes such as <tt>Chat</tt> and <tt>GroupChat</tt>
|
|
provide higher-level constructs that manage creating and sending packets
|
|
automatically, but you can also create and send packets directly. Below
|
|
is a code example for changing the presence to let people we're unavailable
|
|
because we're out fishing:<p>
|
|
|
|
<div class="code">
|
|
<pre>
|
|
<font color="gray"><i>// Create a new presence. Pass in false to indicate we're unavailable.</i></font>
|
|
Presence presence = new Presence(false);
|
|
presence.setStatus(<font color="green">"Gone fishing"</font>);
|
|
<font color="gray"><i>// Send the packet (assume we have a XMPPConnection instance called "con").</i></font>
|
|
con.getPacketWriter().sendPacket(presence);
|
|
</pre></div>
|
|
<p>
|
|
|
|
Every connection has a <tt>PacketReader</tt> and <tt>PacketWriter</tt>. The
|
|
packet reader listens for XML data from the server and parses it into
|
|
individual packets. You can listen for incoming packets by registering
|
|
<tt>PacketWatcher</tt> objects with the packet reader. The packet writer
|
|
is responsible for writing packets to the server. It takes <tt>Packet</tt>
|
|
objects and converts them to XML before sending them over the network.
