Calling an EJB from another ear

Hi,
Here is my problem.

I have an application "A" which is deployed on a remote server. This
application have an EJB in it (ejbA).

In need to implement an EJB (ejbB) on another application B, on another server,
and these EJBB need to call the EJBA contains in A.

For that i use this code :

Properties properties = new Properties();
properties.put("java.naming.factory.initial","org.ow2.carol.jndi.spi.MultiOrbInitialContextFactory");
properties.put("java.naming.provider.url", "rmi://myremoteserverA");
properties.put("java.naming.factory.url.pkgs", "org.objectweb.jonas.naming");
Context jndiContext = new InitialContext(properties);
Object manager	= 
jndiContext.lookup("myapplicationABean_myApplicationABeanRemote@Remote");
home = (myApplicationABeanRemote) 
javax.rmi.PortableRemoteObject.narrow(manager, myApplicationABeanRemote.class);


I've made an ear containing my ejbB.jar and in the ejbB.jar's MANIFEST.MF i've
put the ejbA.jar

When i try to access my EJBB i have this error :

2011-04-26 17:40:31,961 : LogUtils.log : Application has thrown exception,

And the weird part, is, when I put the ejbA.jar in the jonas directory lib/ext,
the application works.

But I don't want to put it in lib/ext, so what can I do ?
