I don't think you can add a method other than finders, creaters to the
EJB home. The reason is that EJB home is an interface that has no
implementation. The calls are delegated and implemented by the
container. This is 100% controlled by the vendor, the application
developer has absolutely no control over it. A vendor can not possibly
forsee what method you are going to need, let alone implementing it.
To solve your problem, I would recommend using a stateless session bean
to return the type you need.
