Requirements
|
|
</p>
|
|
|
|
The only requirement for Smack is JDK 1.2 or later<sup>
|
|
<a style="text-decoration:none;" href="#ssenote">1</a></sup>.
|
|
An XML parser is embedded in the smack.jar file and no other third party
|
|
libraries are required.<p>
|
|
|
|
<sup>1</sup> <font size="-1"><i>JDK 1.2 and 1.3 users that wish to use SSL connections must have the
|
|
<a href="http://java.sun.com/products/jsse/index-103.html">JSSE</a> library in their classpath.</i></font>

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.

Reading and Writing Packets
|
|
</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 our presence to let people know 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(Presence.Type.UNAVAILABLE);
|
|
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.sendPacket(presence);
|
|
</pre></div>
|
|
<p>
|
|
|
|
Smack provides two ways to read incoming packets: <tt>PacketListener</tt>, and
|
|
<tt>PacketCollector</tt>. Both use <tt>PacketFilter</tt> instances to determine
|
|
which packets should be processed. A packet listener is used for event style programming,
|
|
while a packet collector has a result queue of packets that you can do
|
|
polling and blocking operations on. So, a packet listener is useful when
|
|
you want to take some action whenever a packet happens to come in, while a
|
|
packet collector is useful when you want to wait for a specific packet
|
|
to come through. Packet collectors and listeners can be created using the
|
|
connection object.
