Question

I have a JBOSS ESB that uses a standard out of the box EJBProcessor action. How do I get hold of an exception, if the exception be thrown in the method call that was run in the EJB?

Any advice would be helpful.

Answer 1

You can subclass EJBProcessor and override the process method like this:

@Override
public Message process(Message pMessage) {
  try {
    pMessage = super.process(pMessage);
  } catch (Throwable wEx) {
    handleProcessError(pMessage, wEx);
  }
  return pMessage;
}

You will more than likely catch an instance of ActionProcessingException, and you can look at the cause to see the exception in your EJB.

Your action configuration in your jboss-esb.xml will remain exactly the same, except you will substitute the name of your subclass for org.jboss.soa.esb.actions.EJBProcessor.
