What is the simplest way to convert EJB 2.0 (WebLogic 8.1) project to EJB 3.0 (OAS or WebLogic etc)?
I found just this article "Converting an EJB 2.0 Entity Bean to EJB 3.0", which could automate this process, but forced to do too much manual manipulations.
IMO, you can't really convert an EJB 2.1 project to an EJB 3.x project. You can however migrate and this is a project by itself. Some more resources:
