I have a stateless bean injected by container. When called, this bean throws a checked exception (Failure). But the exception that caller catches is runtime exception (IllegalStateException).
Here is a short example:
class Failure extends Exception {
...
}
@Local
public interface OutputQueueHandler {
public void handle(...) throws Failure;
}
@Stateless
public class OutputQueueHandlerBean implements OutputQueueHandler {
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
public void handle(...) throws Failure {
try {
...
persistError('ACK'); // 1.A
throw new Failure(); // 1.B
...
}
catch (RuntimeException e) {
throw new Failure(e);
}
}
}
@MessageDriven(...)
@Depends(...)
public class OutputQueueMDB implements MessageListener {
@EJB
OutputQueueHandler outputQueueHandler;
public void onMessage(javax.jms.Message message) {
...
try {
outputQueueHandler.handle(...); // 2
}
catch (RuntimeException e) {
persistError('HANDLE'); // 3
}
...
}
}
I have read somewhere that it is OK to throw checked exceptions. All I can find now is
http://www.devx.com/Java/Article/30496/1763/page/3 (search for text "Exception Handling")
Is it because the bean method is annotated with TransactionAttributeType.REQUIRES_NEW?
How can I get my original exception?
My environment is JBoss 4.2.1 GA with EJB 3.0
Thanks,
Tvrtko
