<p>This will setup the JNDI for the ConectionFactory and Topic to work within Tomcat.</p>

<p>Here is some example code that will publish a test message to the MY.TEST.FOO Topic:</p>
<div class="code panel pdl" style="border-width: 1px;"><div class="codeContent panelContent pdl">
<script class="brush: java; gutter: false; theme: Default" type="syntaxhighlighter"><![CDATA[
try {
    InitialContext initCtx = new InitialContext();
    Context envContext = (Context) initCtx.lookup(&quot;java:comp/env&quot;);
    ConnectionFactory connectionFactory = (ConnectionFactory) envContext.lookup(&quot;jms/ConnectionFactory&quot;);
    Connection connection = connectionFactory.createConnection();
    Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
    MessageProducer producer = session.createProducer((Destination) envContext.lookup(&quot;jms/topic/MyTopic&quot;));

    Message testMessage = session.createMessage();
    testMessage.setStringProperty(&quot;testKey&quot;, &quot;testValue&quot;);
    producer.send(testMessage);
} catch (NamingException e) {
    // TODO handle exception
