Creating a Connection
|
|
</p>
|
|
|
|
<p>
|
|
The <tt>org.jivesoftware.smack.XMPPConnection</tt> class manages your connection to an XMPP
|
|
server. A default implementation is the <tt>org.jivesoftware.smack.XMPPTCPConnection</tt>
|
|
class. Two constructors are mainly used. The first, <tt>XMPPTCPConnection(String)</tt> takes
|
|
the server name you'd like to connect to as an argument. All default connection settings will
|
|
be used:
|
|
<ul>
|
|
<li>A DNS SRV lookup will be performed to find the exact address and port (typically 5222)
|
|
that the server resides at.</li>
|
|
<li>The maximum security possible will be negotiated with the server, including TLS encryption,
|
|
but the connection will fall back to lower security settings if necessary.
|
|
</li>
|
|
<li>The XMPP resource name "Smack" will be used for the connection.</li>
|
|
</ul>
|
|
|
|
Alternatively, you can use the <tt>XMPPTCPConnection(ConnectionConfiguration)</tt> constructor to
|
|
specify advanced connection settings. Some of these settings include:
|
|
|
|
<ul>
|
|
<li>Manually specify the server address and port of the server rather than using a DNS SRV
|
|
lookup.</li>
|
|
<li>Enable connection compression.</li>
|
|
<li>Customize security settings, such as flagging the connection to require TLS encryption
|
|
in order to connect.</li>
|
|
<li>Specify a custom connection resource name such as "Work" or "Home". Every connection
|
|
by a user to a server must have a unique resource name. For the user "jsmith@example.com", the
|
|
full address with resource might be "jsmith@example.com/Smack". With unique resource names, a user
|
|
can be logged into the server from multiple locations at once, or using multiple devices. The
|
|
presence priority value used with each resource will determine which particular connection
|
|
receives messages to the bare address ("jsmith@example.com" in our example).</li>
|
|
</ul>

Connect and Disconnect
|
|
</p>
|
|
|
|
<div class="code">
|
|
<pre>
|
|
<font color="gray"><i>// Create the configuration for this new connection</i></font>
|
|
ConnectionConfiguration config = new ConnectionConfiguration(<font color="green">"jabber.org"</font>, 5222);
|
|
config.setCompressionEnabled(true);
|
|
|
|
AbstractXMPPConnection connection = new XMPPTCPConnection(config);
|
|
<font color="gray"><i>// Connect to the server</i></font>
|
|
connection.connect();
|
|
<font color="gray"><i>// Log into the server</i></font>
|
|
connection.login(<font color="green">"username"</font>, <font color="green">"password"</font>, <font color="green">"SomeResource"</font>);
|
|
....
|
|
<font color="gray"><i>// Disconnect from the server</i></font>
|
|
connection.disconnect();
|
|
</pre></div>
|
|
|
|
<p>
|
|
By default Smack will try to reconnect the connection in case it was abruptly disconnected. Use
|
|
<i>ConnectionConfiguration#setReconnectionAllowed(boolean) to turn on/off this feature. The reconnection
|
|
manager will try to immediately reconnect to the server and increase the delay between attempts as
|
|
successive reconnections keep failing.</i>
|
|
<br>
|
|
In case you want to force a reconnection while the reconnetion manager is waiting for the next
|
|
reconnection, you can just use <i>AbstractXMPPConnection#connect()</i> and a new attempt will be made.
|
|
If the manual attempt also failed then the reconnection manager will still continue the
|
|
reconnection job.
