Integrating ActiveMQ 5.1 with Tomcat 6

Step 1: Add resource entry to CATALINA_HOME/conf/server.xml under GlobalNamingResources..

    <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" 
useEmbeddedBroker="false" 
    /> 
    <Resource 
name="jms/Data" 
auth="Container" 
type="org.apache.activemq.command.ActiveMQTopic" 
description="Data Topic" 
factory="org.apache.activemq.jndi.JNDIReferenceFactory" 
physicalName="queue.data"
    />

Step 2: Add resource link entry to CATALINA_HOME/conf/context.xml (For God knows What reason, An entry the context.xml in META-INF of my webapp did not work)

<ResourceLink global="jms/ConnectionFactory" name="jms/ConnectionFactory" type="javax.jms.ConnectionFactory"/> 
<ResourceLink global="jms/Data" name="jms/Data" type="javax.jms.Topic"/>

Step 3: Add resource ref entry in web.xml

    <resource-ref> 
        <res-ref-name>jms/ConnectionFactory</res-ref-name> 
        <res-type>javax.jms.ConnectionFactory</res-type> 
        <res-auth>Container</res-auth> 
        <res-sharing-scope>Shareable</res-sharing-scope> 
    </resource-ref> 
    <resource-ref> 
        <res-ref-name>jms/Data</res-ref-name> 
        <res-type>javax.jms.Topic</res-type> 
        <res-auth>Container</res-auth> 
        <res-sharing-scope>Shareable</res-sharing-scope> 
    </resource-ref> 

Step 4: Put the following jars in CATALINA_HOME/lib from ActiveMQ_HOME/lib
activemq-core-5.1.0.jar
commons-logging-1.1.jar
geronimo-j2ee-management_1.0_spec-1.0.jar
geronimo-jms_1.1_spec-1.1.1.jar
geronimo-jta_1.0.1B_spec-1.0.1.jar

Step 5: Start the server, you should be able to use JNDI to connect to ActiveMQ.

Step 6: When you use IntialContext in your code, first get the context of "java:comp/env".

    Context initCtx = new InitialContext(); 
    jndiContext = (Context) initCtx.lookup("java:comp/env"); 
    Then you can use: 
    connectionFactory = (ConnectionFactory)jndiContext.lookup("jms/ConnectionFactory"); 
    destination = (Destination)jndiContext.lookup("jms/Data"); 

Then, carry on with normal JMS flow.
