I have an app, deployed as an EAR. It worked fine on 3.0.6. On 3.0.7, however, it seems I can only instantiate ejbs from jsp-pages (via a taglib) just after jboss restart. If I deploy a new version of the ear, the ejb's will not be instantiated due to a class cast exception, until I restart jboss again. Using the same ejb from a normal java-client works just fine all the time, as far as I can see.

I'm running jboss/jetty version. The ejb's in question are session facades in front of cmp 2.0 ejbs. I get a class cast exeption, and my code looks like this:

public SesCMS getSesCmsBean() throws EJBUtilsException {
System.err.println("EJBUtils.getSesCmsBean");
try { return ((SesCMSHome)PortableRemoteObject.narrow(getInitialContext().lookup("SesCMS"),
SesCMSHome.class)).create() ;
} catch (Exception e) {
e.printStackTrace();
throw new EJBUtilsException("Couldn't get SesCmsBean due to: " + e.getMessage());
}
}

The actual error is:
