Establishing a Connection

The <tt>XMPPConnection</tt> class is used to create a connection to an

<p>Note that maximum security will be used when connecting to the server by default (and when possible),
including use of TLS encryption. The ConnectionConfiguration class provides advanced control
over the connection created, such as the ability to disable or require encryption.</p>
<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.

</div>
<p>
Sending messages back and forth is at the core of instant messaging. Two classes
aid in sending and receiving messages:
<ul>
<li> <tt>org.jivesoftware.smack.Chat</tt> -- used to send messages between two people.
<li> <tt>org.jivesoftware.smack.GroupChat</tt> -- used to join a chat room to send messages between many people.
</ul>
Both the Chat and GroupChat classes use the <tt>org.jivesoftware.smack.packet.Message</tt> packet
class to send messages. In certain circumstances, you may wish to bypass the higher-level
Chat and GroupChat classes to send and listen for messages directly.
Sending messages back and forth is at the core of instant messaging. Although individual messages
can be sent and received as packets, it's generally easier to treat the string of messages
as a chat using the <tt>org.jivesoftware.smack.Chat</tt> class.

The Chat object allows you to easily listen for replies from the other chat participant.
The following code snippet is a parrot-bot -- it echoes back everything the other user types.<p>
You'll also notice in the example above that we specified a MessageListener when creating a chat.
The listener is notified any time a new message arrives from the other user in the chat.
The following code snippet uses the listener as a parrot-bot -- it echoes back everything the other user types.<p>
<div class="code"><pre>
<font color="gray"><i>// Assume we've created an XMPPConnection name "connection".</i></font>
Chat newChat = connection.createChat(<font color="green">"jsmith@jivesoftware.com"</font>);

<font color="gray"><i>// Send back the same text the other user sent us.</i></font>
newChat.sendMessage(message.getBody());
chat.sendMessage(message.getBody());
}
</pre></div><p>
The code above uses the <tt>Chat.nextMessage()</tt> method to get the next message, which
will wait indefinitely until another message comes in. There are other methods to wait
a specific amount of time for a new message, or you can add a listener that will be notified
every time a new message arrives.
<p class="subheader">
GroupChat
</p>
A group chat connects to a chat room on a server and allows you to send and receive messages
from a group of people. Before you can send or receive messages, you must join the room using
a nickname. The following code snippet connects to a chat room and sends a
message.<p>
<div class="code"><pre>
<font color="gray"><i>// Assume we've created an XMPPConnection name "connection".</i></font>
GroupChat newGroupChat = connection.createGroupChat(<font color="green">"test@jivesoftware.com"</font>);
<font color="gray"><i>// Join the group chat using the nickname "jsmith".</i></font>
newGroupChat.join(<font color="green">"jsmith"</font>);
<font color="gray"><i>// Send a message to all the other people in the chat room.</i></font>
newGroupChat.sendMessage(<font color="green">"Howdy!"</font>);
</pre></div><p>
In general, sending and receiving messages in a group chat works very similarly to
the <tt>Chat</tt> class. Method are also provided to get the list of the other
users in the room.<p>
