Hi, I have a problem getting ActiveMQ to work with Tomcat6 correctly.
I have created a minimal web app with a Spring MDP that works great if
I use Eclipse with WTP. Clean tomcat6, clean eclipse. New web project.
However, if I export the app as a war and deploy to an external (also
CLEAN) Tomcat I get this error:
Caused by: javax.naming.NamingException: Cannot create resource
instance
at
org.apache.naming.factory.ResourceEnvFactory.getObjectInstance(ResourceEnvFactory.java:114)
...
I can't seem to figure out why it should differ with WTP contra
standalone tomcat. Anyone that can help me out here? (I have a zip file
if anyone is interested)
I have tried to place my resources in various places: server.xml, in
the context tag in server.xml, in a context.xml in root/meta-inf but
with the same result.
I have also tried to access the resource in a plain servlet without
Spring with the same result. Here are my configuration below:
I have this in my context.xml:
<Resource name="jms/test/cfTEST001" 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/test/TEST001FirstQueue" auth="Container"
type="org.apache.activemq.command.ActiveMQQueue"
description="Receiving messages on this queue"
factory="org.apache.activemq.jndi.JNDIReferenceFactory"
physicalName="Q1" />
and then in my web.xml:
<resource-env-ref>
<resource-env-ref-name>
jms/test/cfTEST001
</resource-env-ref-name>
<resource-env-ref-type>
javax.jms.QueueConnectionFactory
</resource-env-ref-type>
</resource-env-ref>
<resource-env-ref>
<resource-env-ref-name>
jms/test/TEST001FirstQueue
</resource-env-ref-name>
<resource-env-ref-type>javax.jms.Queue</resource-env-ref-type>
</resource-env-ref>
and to try things out I created a servlet with this code:
InitialContext initCtx = new InitialContext();
Context envContext = (Context) initCtx.lookup("java:comp/env");
ConnectionFactory connectionFactory = (ConnectionFactory)
envContext.lookup("jms/test/cfTEST001");
Connection connection = connectionFactory.createConnection();
Session session = connection.createSession(false,
Session.AUTO_ACKNOWLEDGE);
MessageProducer producer = session.createProducer((Destination)
envContext.lookup("jms/test/TEST001FirstQueue"));
TextMessage testMessage = session.createTextMessage();
testMessage.setText("My Message);
producer.send(testMessage);
This works just fine running in Eclipse/WTP but not in plain Tomcat.
Anyone here that can tell me why?
