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.
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.
