Subject Re: ActiveMQ and EJB3 - tested with JBoss

Thanks Daniel!

I think my problem is the missing @ResourceAdapter annotation. But, do you
know in which jar I can find the org.jboss.annotation.ejb.ResourceAdapter
annotation? I work on JBoss 4.2.2GA and i can't find the package
"org.jboss.annotation" anywhere ... :-( Must I install a additionaly JBoss
package? Or where else can I find the annotation?

Many thanks,
Steffen
