Case

On generating Locals and Remotes of EJBs (let’s say JonathanBean) to be deployed on JOnAS, the GenIC raises:
[java]GenIC.fatalError : GenIC fatal error: Cannot read the Deployment Descriptors from /foo/goo/jonathan-server.jar: Method foo of interface lalou.jonathan.JonathanLocal should NOT throw RemoteException[/java]

Within the EJB2, the method foo is declared to be Local and to throw RemoteException

Quickfix

The error is explicit.

A Local EJB cannot throw RemoteException.
Especially, the considered method can be declared with the right XDocLet tag, ie:

[java]* @ejb.interface-method view-type="remote"[/java]

but can with neither:
[java]* @ejb.interface-method view-type="both"[/java]

nor:
[java]* @ejb.interface-method view-type="local"[/java]

As a quickfix, I suggest to surround with a try/catch block a throw a RuntimeException if needed.

Case

Trying to deploy an EAR on JOnAS, I got the following error:
[java]Problems when invoking main method from GenIC: java.lang.RuntimeException: error in fastrmic (null)[/java]

More detail:

[java]JOnASEJBService.__checkGenIC : Cannot apply GenIC on the file ‘C:\jonathan\jonathan_2012.05.11-13.47.29.ear\jonathan-server.jar’ with the args ‘[-classpath, C:\jonathan\jonathan_2012.05.11-13.47.29.ear\jonathan-server.jar, -protocols, jrmp, -invokecmd]’.

Quickfix

Edit $JONAS_BASE/conf/jonas.properties.
The properties jonas.services and jonas.service.ejb2.auto-genic must be consistent.

Especially, if GenIC is enabled (jonas.service.ejb2.auto-genic true), then check ejb2 is among the services pointed at by jonas.services, eg:
jonas.services jtm,db,security,resource,ejb2,web,ear.
