How to migrate the .ejb files from weblogic to JBoss EAP 6?

Issue

• There is a weblogic project that uses .ejb files with ejbgen to generate the ejbs. Is there a way to port them JBoss?
• Should the ejbs be re-written in J2EE manner or is there a way to reuse those .ejb files?
• What is the right way to migrate .ejb files?
• We are trying to migrate our application from WebLogic 10.3 to Jboss EAP 6.2 and running into an issue with EJB configuration. I am not sure if we have to do some additional configuration for EJB in JBoss6.2. Any help is greatly appreciated.
