jBPM and Exception problem

drapierwim May 28, 2006 12:41 PM

I have a SFSB method that is a part of my jBPM pageflow, when the UnValidBookingExeption is thrown i get an error, what is wrong here?

public void addBooking() {
 if(transaction == null)
 createTransaction();
 try {
 transaction.add(booking);
 bookings = transaction.getBookings();
 } catch (UnValidBookingException e) {
 facesMessages.add(FacesMessage.SEVERITY_WARN,"#{messages['missing.account']}");
 } catch (ImmutableTransactionException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 }

The error

1. Re: jBPM and Exception problem

Looks like jBPM is being naughty and swallowing the underlying exception. Bad jBPM!

What version of jBPM is this?

But a breakpoint in addBooking() and find the real exception.

seems that this is a problem copied from el: the root cause is a special member instead of using the exception cause.

public class ELException
 extends Exception
{
 private static final long serialVersionUID = 1L;

 //-------------------------------------
 // Member variables
 //-------------------------------------

 private Throwable mRootCause;

 //-------------------------------------
 /**
 * Creates an ELException with no detail message.
 **/
 public ELException ()
 {
 super ();
 }

 //-------------------------------------
 /**
 * Creates an ELException with the provided detail message.
 *
 * @param pMessage the detail message
 **/
 public ELException (String pMessage)
 {
 super (pMessage);
 }

 //-------------------------------------
 /**
 * Creates an ELException with the given root cause.
 *
 * @param pRootCause the originating cause of this exception
 **/
 public ELException (Throwable pRootCause)
 {
 super( pRootCause.getLocalizedMessage() );
 mRootCause = pRootCause;
 }

 //-------------------------------------
 /**
 * Creates an ELException with the given detail message and root cause.
 *
 * @param pMessage the detail message
 * @param pRootCause the originating cause of this exception
 **/
 public ELException (String pMessage,
 Throwable pRootCause)
 {
 super (pMessage);
 mRootCause = pRootCause;
 }

 //-------------------------------------
 /**

 *
 * @return the root cause of this exception

 public Throwable getRootCause ()
 {
 return mRootCause;
 }
}

Ok something wierd happend here, i've restarted my AS marked my method with a breakpoint and started debugging... result everything worked well.

The only thing I've done was making the transaction(entity) class a non seam component again, don't know if that was the problem. I will surely test this again later on, Thanks
