Smack includes a built-in debugging console that will let you track all XML traffic between
|
||||||
|
the client and server.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
When debugging mode is enabled, a debug window will appear when each new connection is created.
|
||||||
|
The window will contain the following information:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<img src="images/debugwindow.gif" width="359" height="399" alt="" border="0" align="right">
|
||||||
|
|
||||||
|
<ul>
|
||||||
|
<li>Client Traffic (red text) -- raw XML traffic generated by Smack and sent to the server.
|
||||||
|
<li>Server Traffic (blue text) -- raw XML traffic sent by the server to the client.
|
||||||
|
<li>Interpreted Packets (green text) -- shows XML packets from the server as parsed by Smack.
|
||||||
|
</ul>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
Debugging mode can be enabled in two different ways:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<ol>
|
||||||
|
<li>Add the following line of code before creating new connections:<p>
|
||||||
|
<tt>XMPPConection.DEBUG_ENABLED = true;</tt><p>
|
||||||
|
|
||||||
|
<li>Set the Java system property <tt>smack.debugEnabled</tt> to true. The
|
||||||
|
system property can be set on the command line such as:<p>
|
||||||
|
<tt>java SomeApp -Dsmack.debugEnabled=true</tt>.
|
||||||
|
</ol>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
If you wish to explicity disable debug mode in your application, including using the command-line parameter,
|
||||||
|
add the following line to your application before opening new connections:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
<tt>XMPPConnection.DEBUG_ENABLED = false;</tt>

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.

Smack is a library for communicating with XMPP (Jabber) servers to perform
|
||||||
|
instant messaging and chat.
|
||||||
|
|
||||||
|
<p class="subheader">
|
||||||
|
Key Advantages:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<ul>
|
||||||
|
<li>Extremely simple to use, yet powerful API. Sending a text message to a user
|
||||||
|
can be accomplished in three lines of code:
|
||||||
|
|
||||||
|
<div class="code"><pre>
|
||||||
|
XMPPConnection connection = <font color="navy"><b>new</b></font> XMPPConnection(<font color="green">"jabber.org"</font>);
|
||||||
|
connection.login(<font color="green">"mtucker"</font>, <font color="green">"password"</font>);
|
||||||
|
connection.createChat(<font color="green">"jsmith@jivesoftware.com"</font>).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>GroupChat</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.
|
||||||
|

Smack provides an easy mechanism for attaching arbitrary properties to packets. Each property
|
||||||
|
has a String name, and a value that is a Java primitive (int, long, float, double, boolean) or
|
||||||
|
any Serializable object (a Java object is Serializable when it implements the Serializable
|
||||||
|
interface).

||||||

<p class="subheader">

Using the API
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
All major objects have property support, such as Message objects. The following code
|
||||||
|
demonstrates how to set properties:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<div class="code"><pre>
|
||||||
|
Message message = chat.createMessage();
|
||||||
|
<font color="gray"></i>// Add a Color object as a property.</i></font>
|
||||||
|
message.setProperty(<font color="blue">"favoriteColor"</font>, new Color(0, 0, 255));
|
||||||
|
<font color="gray"></i>// Add an int as a property.</i></font>
|
||||||
|
message.setProperty(<font color="blue">"favoriteNumber"</font>, 4);
|
||||||
|
chat.sendMessage(message);
|
||||||
|
</pre></div>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
Getting those same properties would use the following code:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<div class="code"><pre>
|
||||||
|
Message message = chat.nextMessage();
|
||||||
|
<font color="gray"></i>// Get a Color object property.</i></font>
|
||||||
|
Color favoriteColor = (Color)message.getProperty(<font color="blue">"favoriteColor"</font>);
|
||||||
|
<font color="gray"></i>// Get an int property. Note that properties are always returned as
|
||||||
|
// Objects, so we must cast the value to an Integer, then convert
|
||||||
|
// it to an int.</i></font>
|
||||||
|
int favoriteNumber = ((Integer)message.getProperty(<font color="blue">"favoriteNumber"</font>)).intValue();
|
||||||
|
</pre></div>
|
||||||
|
|
||||||
|
<p class="subheader">
|
||||||
|
Objects as Properties
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
Using objects as property values is a very powerful and easy way to exchange data. However,
|
||||||
|
you should keep the following in mind:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<ul>
|
||||||
|
<li>When you send a Java object, only clients running Java will be able to interpret the data.
|
||||||
|
So, consider using a series of primitive values to transfer data instead.
|
||||||
|
|
||||||
|
<li>Objects sent as property values must implement Serialiable. Additionally, both the sender
|
||||||
|
and receiver must have identical versions of the class, or a serialization exception
|
||||||
|
will occur when de-serialiazing the object.
|
||||||
|
|
||||||
|
<li>Serialized objects can potentially be quite large, which will use more bandwidth and
|
||||||
|
server resources.
|
||||||
|
</ul>
|
||||||
|
|
||||||
|
<p class="subheader">
|
||||||
|
XML Format
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
The current XML format used to send property data is not a standard, so will likely not be
|
||||||
|
recognized by clients not using Smack. The XML looks like the following (comments added for
|
||||||
|
clarity):
