[jboss-user] [JBoss jBPM] - Exception when invoking a WebService within an ActionHandler

[mavrides]

Hi all,

I have searched everywhere to find an answer to this question.

I try to invoke a very simple webservice from within an ActionHandler but I get an exception.

Code:

  | public void execute(ExecutionContext context) throws Exception {
  | 		try {
  | 	           String endPoint = 
  | 	               "http://localhost:8080/axis/CruiseServiceImpl.jws";	       
  | 	           // Set up the remote method call
  | 	           Service  service = new Service();}
  | 	           call.setTargetEndpointAddress( new java.net.URL(endPoint));
  | 	           call.setOperationName( new QName("CruiseServiceImpl", "cruiseDestinations") );
  | 	           // Perform the remote call
  | 	           String[] ret = (String[])call.invoke(new Object[0]);
  | 	           System.out.println("Destinations:");
  | 	           for (int i = 0; i < ret.length; i++) {
  | 	               String s = ret;
  | 	               System.out.println(s);
  | 	           }            
  | 	        } catch (Exception e) {
  | 	           e.printStackTrace();
  | 	        }
  | 	        context.getContextInstance().setVariable("message", message);
  | 			
  | 	}
  | 

And here is the exception:

  | description The server encountered an internal error () that prevented it from fulfilling this request.

  | 
  | note The full stack trace of the root cause is available in the Apache Tomcat/5.5 logs.
  | 

Please note:
1) Everything runs great when I test this with JUnit. The exception occurs when I try to run the process from within jbpm, after pressing "Save and Close Task".
2) I have no idea where to find the tomcat logs since it is embedded within jbpm 3.1.2 in my case, that is why I haven't looked at them.

Any help as in why this happens or where to find the logs would be greatly appreciated.

Thank you!
