Hello there,
I've a problem getting Interceptors to work in our EJB3-Application.
I looked over the samples given in the EJB3Trail as well as in the tutorials
available at jboss.com and implemented it accordingly, BUT it does not work,
although the examples do work. I investigated this a little further and found
that Interceptors only seem to work in certain context.
I have a class A which is derived from an abstract class B. A implements an
interface C which defines the business-methods for A. This interface is derived
from interface D which defines business-methods implemented by B.
| public abstract class B{
| private static Logger logger = Logger.getLogger(B.class);
| @AroundInvoke
| public testAroundInvoke(InvocationContext ctx) throws Exception{
| logger.info("B.testAroundInvoke");
| return ctx.proceed();
| }
| }
|
| @Local public interface D{
| }
|
| @Local public interface C extends D{
| }
|
| @Stateless
| @Interceptor(TestInterceptor.class)
| public class A extends B implements C{
| ...
| }
|
This way all business-methods of B, as defined by D, are intercepted by both,
the external Interceptor and the internal of class B. Business-methods of A are
not intercepted.
If I remove the AroundInvoke method in B no interceptors at all are called
anymore. Why is that? Am I doing something wrong or is this a bug?
How do I get JBoss to intercept business-methods of A?
Please help.
