[jboss-user] [JBoss jBPM] - Token.signal() for bpel process definitions

[b_]

Hi all, 

I am trying to do something similar to the HelloWorld example (that ships with jbpm-jpdl), but through a bpel process definition.

This is the code for the jpdl helloWorld example:


  | 
  | ProcessDefinition processDefinition = ProcessDefinition.parseXmlString(
  |     "<process-definition>" +
  |     "  <start-state>" +
  |        ................
  |        ................
  |     "</process-definition>"
  |   );
  |   
  |   ProcessInstance processInstance = 
  |       new ProcessInstance(processDefinition);
  | 
  |   Token token = processInstance.getRootToken();
  | 
  |   token.signal();
  | 
  | ...
  | ...
  | 

This code works fine ... however when i try to do the same thing using a bpel process definition using the following code:


  | 			
  | 
  | 		ZipInputStream zis = zis = new ZipInputStream(new   
  | BufferedInputStream(Thread.currentThread().getContextClassLoader().getResourceAsStream("helloWorldBpel.zip");));
  | 		
  | 		ProcessArchive processArchive = null ;
  | 		
  | 	
  | 		try {
  | 			processArchive = new ProcessArchive(zis);
  | 		} catch (IOException e) {
  | 			.....
  | 		}
  | 		ProcessDefinition processDefinition =  processArchive.parseProcessDefinition();
  | 		
  | 		  ProcessInstance processInstance = 
  | 		      new ProcessInstance(processDefinition);
  | 
  | 		  Token token = processInstance.getRootToken();
  | 		  
  | 		  token.signal();
  | 
  | 

i get the following exception:

  | Is this possible to do with a  bpel process definition? (there is infact a package org.jbpm.bpel.graph.exe which i guess contains execution related artifacts for bpel graph definitions). Am i missing something?
