Subject Re: How to access ejb in Gbean??? then IllegalArgumentException: interface org.apache.openejb.client.EJBObjectProxy is not visible from class loader was throw
Date Sun, 27 Nov 2011 06:17:34 GMT
Suppose that you are trying to access remote ejb reference from OpenEJB
container, not from the java:comp directory, as GBean is not managed bean,
IIRC.
Since the stacktrace shows that OpenEJB related classes could not be loaded
from the context classloader, have you tried to add the openejb plugin
dependency in your deployment plan ?
