[jbpm-users] [JBoss jBPM] - Consuming webservice in jBPM JPDL (Eclipse)
Hi guys
Starting to get better at this stuff - i have a really annoying problem with consuming
webservices in jBPM though.
Until now i have been making processes calling internal stuff, and using a lot of
examples.
My first step into the real world is consuming a webservice.
I made the webservice myself, its a simple java webservice adding two numbers together. I
have tested it by implementing a client in NetBeans IDE 6.1, and it works like a charm. I
have copied the code to jBPM and made a simple process executing it.
To make things even more simple i have put the webservices code in the same package as the
client itself, i was unsure whether it actually deployed the files...
Here it is:
package com.sample.action;
|
| import org.apache.commons.logging.Log;
| import org.apache.commons.logging.LogFactory;
| import org.jbpm.graph.def.ActionHandler;
| import org.jbpm.graph.exe.ExecutionContext;
|
| public class isbncheck implements ActionHandler {
|
| private static final long serialVersionUID = 1L;
|
| public void execute(ExecutionContext executionContext) throws Exception
| {
| String msg;
| try
| {
| log.info("##############################");
| log.info("Debug:1");
| CalculatorWSService service = new CalculatorWSService();
| log.info("Debug:2");
| CalculatorWS port = service.getCalculatorWSPort(); //TODO: Error - wtf?
| log.info("Debug:3");
| int i = 3;
| int j = 400000;
| int result = port.add(i, j);
| msg = "Result = "+result;
| }
| catch (Exception ex)
| {
| msg = "Error: " + ex.getMessage();
| }
| log.info(msg);
| log.info("##############################");
| executionContext.leaveNode();
| }
|
| private static final Log log = LogFactory.getLog(isbncheck.class);
| }
When running this, my webserver (tomcat 6) sends the following output.
anonymous wrote : 09:42:45,912 INFO [isbncheck] ##############################
| 09:42:45,912 INFO [isbncheck] Debug:1
| 09:42:45,943 INFO [isbncheck] Debug:2
| 09:42:45,975 INFO [isbncheck] Error: Cannot load service endpoint interface:
com.sample.action.CalculatorWS
| 09:42:45,975 INFO [isbncheck] ##############################
As you might have guessed by the name of the class i have tried with another webservice
with the same error (an ISBN check webservice). In both cases i can create the service,
but when calling the service.get*Whatever*Port() i get the error. I've been googling
like a mad-man but nobody seems to have this problem, so what am i doing wrong?
Btw. i'm sure it's a simple question, but how do i do the
"printstacktrace" to the webserver console so i can see the full error?
Thanks in advance.
