Hi,
I think that the following error:
> Cannot read the deployment descriptors 'test2.jar':
> org.objectweb.jonas.deployment.api.DeploymentDescException:
> META-INF/ejb-jar.xml resource not found
>
is due to the fact that test2.jar is not in the directory where
you have launched the EJBServer
You must give as "-a" parameter of JOnASAdmin an absolute path to the
test2.jar
or a relative path to the directory where you have run EJBServer.
Unfortunately in this case, ejb-jar.xml will be found but
you may have problem if registry has been launched without
the visibility of test2.jar
I am afraid you will have this sort of exception:
java.lang.ClassNotFoundException: xxx.yyy.JOnASZZHome_Stub]
I am not sure that you can bypass this problem by using
-Djava.rmi.server.codebase when you start EJBServer.
So I think that if you want to deploy new beans without
restarting the server you must de-jar the ejb-jar file
in order to install the classes in a place viewed via
the CLASSPATH of the registry and EJBServer,
and deploy the bean in the running server via
JonasAdmin -a xxx.xml
This may be considered as a bug in JOnAS or a restriction.
As you know JOnAS is in open source and all contributions
are welcome! and we'll be very happy if someone in the
jonas-users community want to resolve this problem....
Best regards,
