[jboss-user] [JBoss jBPM] - Re: JBPM BPEL 1.1.1 Getting variables of processInstance

[dhanushgopinath]

I dont think there is any converter as of now.

Here is how I did it

  | 		JbpmContext jbpmContext = GetJbpmConfiguration().createJbpmContext();
  | 		ProcessInstance processInstance = GetJbpmGraphSession(jbpmContext)
  | 				.getProcessInstance(Long.parseLong(strProcessInstanceId));
  | 		
  | 		// Get the context instance
  | 		ContextInstance processContextInstance = processInstance
  | 				.getContextInstance();
  | 		// get the all token variables map
  | 		Map allTokenVariablsMap = processContextInstance.getTokenVariableMaps();
  | 		// get the correct token for the variable
  | 		Token tokenForVariable =  GET THE CORRECT TOKEN HERE FROM THE MAP
  | 		// get the variable from the context instance
  | 		Object variable = processContextInstance.getVariable(strVariableName,
  | 				tokenForVariable);
  | 	
  | 		// Variable will be an instance of MessageValue
  | 		if (variable instanceof MessageValue) {
  | 			MessageValue messageElement = (MessageValue) variable;
  | 			Map partElems = messageElement.getParts();
  | 		
  | 			// Get the first Element
  | 			String partName = (String) partElems.keySet().iterator().next();
  | 			Element partElement = (Element) partElems.values().iterator()
  | 					.next();

The partElement is an XML Element . You can recurse through this and get the values using a DOM Parser.
