Hi folks,

i am writing a simple jboss / ear application to get myself used to dealing with Jboss and EJB.

I googled a lot, but i couldn't find an answer to the problem i have right now:

My project has the common EAR-layout:

- common
- ejb
- webapp
- build.xml

Now my EJB-layer uses one ActiveMQ jar file.

Now i don't know where to put this jar within my EAR-file?

First - in lack of better knowledge and for testing purposes - i put the jar-file just in the root of my EAR-file.

This is simply ignored by Jboss:

java.lang.NoClassDefFoundError: org/apache/activemq/ActiveMQConnectionFactory

But this class is deinitely in the ActiveMQ-jar which resides on the root-level of my EAR:

jar tf activemq-core-5.0-SNAPSHOT.jar | grep -i ActiveMQConnectionFactory
  | org/apache/activemq/ActiveMQConnectionFactory$1.class
  | org/apache/activemq/ActiveMQConnectionFactory.class
  | org/apache/activemq/spring/ActiveMQConnectionFactory.class

So, finally my question......:-)

Where to put application- AND layer-specific jar-files within an EAR?

More specific:

Where to put the ActiveMQ jar-file within my EAR and how do i get Jboss to put it in the classpath?
