<h1>JMS Instantiate Connection Factory Example</h1>
|
|
|
|
<pre>To run the example, simply type <b>mvn verify</b> from this directory, <br>or <b>mvn -PnoServer verify</b> if you want to start and create the server manually.</pre>
|
|
|
|
<p>Usually, JMS Objects such as ConnectionFactories, Queue and Topic instances are looked up from JNDI
|
|
before being used by the client code. This objects are called "administered objects" in JMS specification
|
|
terminology.</p>
|
|
<p>However, in some cases a JNDI server may not be available or desired. To come to the rescue ActiveMQ
|
|
also supports the direct instantiation of these administered objects on the client side.</p>
|
|
<p>This allows the full set of JMS functionality to be available without requiring a JNDI server!</p>
|
|
<p>This example is very simple and based on the simple Queue example, however in this example we
|
|
instantiate the JMS Queue and ConnectionFactory objects directly.</p>
|
|
<p>A wide variety of methods are available for instantiating ConnectionFactory objects. In this example
|
|
we use a simple method which just takes the server connection details so it knows where to make the
|
|
connection to.</p>
|
|
<p>Other methods are available so all the connection factory parameters can be specified
|
|
including specifying UDP discovery so the client does not need hard-wired knowledge of where the servers
|
|
are that it wishes to connect to, or for specifying live-backup pairs of servers for failover.</p>
|
|
<p>For more information on instantiating ConnectionFactories directly please consult the user manual and
|
|
javadoc.</p>
