<div class="wiki-content maincontent"><p>Create the file &lt;webapp-root&gt;/META-INF/context.xml.  Here is an example:</p>
<div class="code panel pdl" style="border-width: 1px;"><div class="codeContent panelContent pdl">
<pre class="brush: java; gutter: false; theme: Default" style="font-size:12px;">
&lt;Context antiJARLocking="true"&gt;
    &lt;Resource
        name="jms/ConnectionFactory"
        auth="Container"
        type="org.apache.activemq.ActiveMQConnectionFactory"
        description="JMS Connection Factory"
        factory="org.apache.activemq.jndi.JNDIReferenceFactory"
        brokerURL="tcp://localhost:61616"
        brokerName="LocalActiveMQBroker"

<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">
<pre class="brush: java; gutter: false; theme: Default" style="font-size:12px;">
try {
    InitialContext initCtx = new InitialContext();
    Context envContext = (Context) initCtx.lookup("java:comp/env");
    ConnectionFactory connectionFactory = (ConnectionFactory) envContext.lookup("jms/ConnectionFactory");
    Connection connection = connectionFactory.createConnection();
    Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
    MessageProducer producer = session.createProducer((Destination) envContext.lookup("jms/topic/MyTopic"));

    Message testMessage = session.createMessage();
    testMessage.setStringProperty("testKey", "testValue");
    producer.send(testMessage);
} catch (NamingException e) {
    // TODO handle exception
} catch (JMSException e) {
    // TODO handle exception
}
</pre>
