java.lang.NoClassDefFoundError: org/jboss/aspects/asynch/Asy

[rossiutilia]

Hi,
I have JBoss 4.01.3 with EJB 3.0 and
I execute the instruction from a java class:
myBean = (MyClass) context.lookup(MyClass.class.getName());

from a thread that is not the main thread of the application, but is a Thread which I create, it gives me this error:

java.lang.NoClassDefFoundError: org/jboss/aspects/asynch/AsynchProvider

Where can I find this class?

Thank you
Alessandro.

I had the same problem in 4.0.4RC1. I downloaded the Jboss-AOP 1.3.5 kit and added the lib-50/jboss-aspect-jkd50-client.jar to my classpath and it fixed the problem.

Shouldn't this jar be in the jbossall-client.jar?
