Am new to EJB 3.0 I have written some sample beans in EJB 2.1, when I deploy 2.1 session bean I normally packed with Jboss.xml file but for ejb 3.0 without that deployment descriptor (Jboss.xml) sessionbean running ... how is that possible ? can ejb 3.0 session bean be deployed in any app server EBA, Oracle without vender specific dd?
The the dd(application.xml) is not required for the int the ejb 3.0, the application server take a look on your module and decide how to deploy it.
At least this is the theory but in the practice, well, you may need it. I occur this problem with jboss 4.XX in an ear which contains two modules and the modules refer each other.
