I have a similar problem:

I just moved my application from JBoss 4.0.1SP1 to 4.0.3 and am seeing this error. Did not see this on 4.0.1SP ??!! Any clue why? or what needs to be done to make the application work on 4.0.3 ??

I get this error:

11:41:33,559 ERROR [LogInterceptor] EJBException in method: public abstract com.aqm.interfaces.UserLocal com.aqm.interfaces.UserLocalHome.findByUserNa
me(java.lang.String,java.lang.String) throws javax.ejb.FinderException:

Great article and good explanation. But I am still not sure what I need to do to make my application work the way it was in 4.0.1SP1. Do I have to dismantle the JARS and WARS to separate common classes? I hope not as this would be impractical if the JARS are for 3rd party components.

I have deployed a very easy EJB app and had the same error.
SOLUTION: remove yourEJBname.jar from WAR archive.

Hi, I am new to this community. I am facing problem when migrating my EJB's from JBoss4.2 to Jboss6.0. The EJB jars working fine in Jboss 4.2 but when same build is deployed on Jboss 6.0 Exception is coming. I have searched on the Internet communities and forums but didn't find solution for this.

Please help me as this is hampering my schedule here.

EJB jars deployed successfully on the server but error comes when I try to access my application.

Please find the error stacktrace below:

I also seem to be going round in circles with this error.  I have an ear built which includes one war file, and the war file includes an ejb client jar.

If I deploy locally to Jboss Version:5.1.0.GA it works without any problem, however if I deploy to EAP 5.1.2 the exception (as below) is thrown.

EJBException:; nested exception is:

          javax.ejb.EJBException: Invalid invocation, check your deployment packaging, method=public abstract com.nnn.ejb.RequestEjbRemote com.nnn.ejb.RequestEjbHome.create() throws java.rmi.RemoteException,javax.ejb.CreateException

Any examples much appreciated.
