I assume your question is related on how to generate a Connect EJB rule ( Records > Integration-Connectors > Connect EJB) for a EJB 3.0 Session Bean.

Pure EJB 3.0 beans are not supported, as for backward compatibility, Pega generates a EJB 2.x client. As such Component Interfaces (Remote or Local Home) are still required.

This shouldn't be a blocker as EJB 3.0 is backward compatible with EJB 2.x clients and local and remote home interfaces as well as initialization methods (e.g. ejbCreate()) are supported by using annotations and/or deployment descriptors.

Please refer to the following documents for details on how to implement backward compatible EJB 3.0 Beans

https://docs.oracle.com/javaee/6/api/index.html?javax/ejb/RemoteHome.html
https://docs.oracle.com/cd/E16439_01/doc.1013/e13981/ses30imp003.htm

Thanks a lot Domenico. This will help us. 

We are yet to implement this, we want to pre-learn if there were any challenges and Pega enablement towards EJB 3.0.

 

We'd prefer it if you saw us at our best.
