How to get root cause of BpmException

Question

Hi all

In the exception handling of new ivy (6.0) we have a new term that is BpmError, i'm catching it but now i want to know what is the rootcause of that exception, so how can i get it from BpmError. Here is the stacktrace of exception: alt text

The read box is the root cause actually that i want to get it out.

Is there any way?

Thanks

The method error.getTechnicalCause() returns the origin thrown exception in the Process Engine. To get the 'root' exception call the method Throwable.getCause() as many times as necessary...

public class BpmErrorUtils {
    public static Throwable getRootCause(BpmError bpmError) {
        Throwable origin = bpmError.getTechnicalCause();
        Throwable parent = origin.getCause();
        while (parent != null) {
            origin = parent;
            parent = origin.getCause();
        }
        return origin;
    }
}

yes, i came up with the similar solution:

   public class CauseFinder {
            private Predicate<Throwable> predicate;

        public CauseFinder(Predicate<Throwable> predicate) {

                       this.predicate = predicate;

          }
         public Throwable findCause(Throwable throwable) {

               Throwable cause = throwable.getCause();

               return cause == null || (cause != null && cause.equals(throwable)) ? null

            : predicate.test(cause) ? cause : findCause(cause);
         }
   }

Continues...

 public class ConcurrencyErrorThrowablePredicate implements Predicate<Throwable> {   
     @Override
  public boolean test(Throwable exception) {

    return exception instanceof ConcurrencyModificationPersistenceException;
       }
}

//When using it Throwable ex = new CauseFinder(new ConcurrencyErrorThrowablePredicate()).findCause(error.getCause());
