Can Jboss auto-generate remote interfaces?
Hi, I'm reading the article at the following path:
http://www.javaworld.com/javaworld/jw-08-2004/jw-0809-ejb-p2.html
which says that the following signature for a slsb:
@Stateless
@Remote
public class HelloWorldBean {
public String sayHello() {
return "Hello World!!!";
}
}
should be enough to have the EJB container to auto-generate a remote interface for us.
I tried and got the following problems at deployment time:
java.lang.RuntimeException: Use of empty @Remote on bean class and there are no valid business interfaces

...etc
The question is: is it possible to have remote interface auto-generated for us? If so, which object could be access from outside the container in order to interact with our session bean? I know it sounds a bit out of the spec, since no client should interact directly with an EJB, but if somehow we could get back a remote object which could be cast to our session bean type, exposing only public methods...then life would be much easier, since I wouldn't have to write an interface for each sb I create.
