This Chat example creates an ActiveMQ broker using the configuration
|
||||
information found in the <code>web.xml</code> file. There isn't much there.
|
||||
Just a name-value parameter named <code>org.apache.activemq.brokerURL</code>
|
||||
is assigned a value of <code>vm://localhost?broker.persistent=false</code>.
|
||||
This is enough however to lazy-initialize the broker when it is needed.
|
||||
</p>
|
||||
<p>
|
||||
The client leverages a javascript library <code>amq.js</code> to perform all
|
||||
of the JMS-related client side code. This involves establishing a
|
||||
communication pipeline to the JMS server. This pipeline uses a long-poll
|
||||
connection to the server. All JMS communication will be received down this
|
||||
pipe, and when the JMS server has no traffic to send, this pipeline will
|
||||
patiently wait until there is new traffic or until it times out. If a
|
||||
timeout does occur, the connection will reconnect to the server for another
|
||||
round. (Of course you will want/need to use a server that supports
|
||||
continuations in order for this to scale beyond a few hundred clients.)
|
||||
</p>
|
||||
<p>
|
||||
The <code>chat.js</code> file contains the script to respond to the UI
|
||||
interactions. It also talks to the <code>amq.js</code> file to send messages
|
||||
and provides a message handler that will respond to incoming JMS messages.
|
||||
</p>
|
||||
<p>
|
||||
There is no server-side state in this application. The client sets up a JMS
|
||||
Topic on the server and attaches itself as a listener to this topic. From
|
||||
that point, all messages that are sent to the topic are received by each
|
||||
listener. Even the list of members in the chat room are the result of
|
||||
clients replying to a ping request.
|
||||
</p>
|
||||
<p>
|
||||
Please note that <code>amq.js</code> has been refactored to allow AJAX calls
|
||||
to be made using any javascript library. Example adapter classes for <a href="http://jquery.com/">jQuery</a>
|
||||
and <a href="http://www.prototypejs.org/">Prototype</a> have been provided.
