Currently we were successful in deploying our ear in WebSphere Single Server Edition 4.0, but now we upgraded to AE and tried to deploy the same ear to WebSphere Advanced edition 4.01 we receive errors. I tried to verify the ear in the application assembly tool and I receive errors for example not public and does not meet EJB 1.1 Specifications. Why would my ear work in Single Server Edition and not in the Websphere Advanced Edition 4.01? Thanks in advance
