[SOLVED] JAX-RS on EJB 3.1 Session Bean which only has Remote Interface

JAX-RS on EJB 3.1 Session Bean which only has Remote Interface

Can I use JAX-RS annotations like @Path on an EJB 3.1 session bean which only has a remote interface?

This works:

@Path("/service")
@Stateless
public class ServiceOne {
    @POST
    @Path("/foo")
    public Response foo() {
        return Response.ok().build();
    }
}

However, if I add a remote interface...

@Remote
public interface ServiceOneRemote {
    Response foo();
}

@Path("/service")
@Stateless
public class ServiceOne implements ServiceOneRemote {
    @POST
    @Path("/foo")
    public Response foo() {
        return Response.ok().build();
    }
}

... I get a NotSerializableException

From articles like Implementing RESTful views of an EJB with local interfaces I get the impression that JAX-RS only works with session beans that have a local interface. But I could not find any resource that explicitly states that it is not possible.

Am I doing something wrong? Or is this just not possible?

Btw: I am running a JBoss EAP 6.4 application server.

Solution

It is not possible. In JSR-339 (The JavaTM API for RESTful Web Services) specification this is stated as follows:

JAX-RS annotations can be applied to methods in an EJB’s local interface or directly to methods in a no-interface EJB.
