Strange [verifier] EJB spec violation problem

[willievu]

org.jboss.ejb.EJBDeployer sometimes failed to deploy my ear. I said sometimes because the ear works the first when server configuration directory is constructed from scratch. If I stop and restart jboss, org.jboss.ejb.EJBDeployer may complain that one of the ejb impls in the ear does not match the signatures of the remote interface.

I double checked the signatures are identical even to the order sequence of exceptions.

Here is the exception:

14:18:34,170 INFO [EARDeployer] Init J2EE application: file:/E:/java/jboss-3.2.3/time/time-rs-test-app/time-r

Any idea why JBoss keeps saying remote interface and impl class are out of synch?

Thanks.

As it turns out, CanceledOperationException is loaded twice in 2 different classloaders. So, exceptions in methods are always considered different.

CanceledOperationException was loaded through scheduler-service.xml and the normal jar deployment.

Resolution - force CanceledOperationException loaded once and only once by putting the jar that contains CanceledOperationException into <jboss server config dir>/lib.

How was the CanceledOperationException being loaded twice? Are you using class loader scoping in the deployment?
