[jboss-user] [JBoss jBPM] - why am i getting a null ProcessDefinition from graphSession.

[james1969]

I'm very new at jBPM.  I'm trying to get a DecisionHandler working in a new workflow I've defined:

  | <?xml version="1.0" encoding="UTF-8"?>
  | 
  | <process-definition
  |         xmlns="urn:jbpm.org:jpdl-3.1"
  |         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  |         xsi:schemaLocation="urn:jbpm.org:jpdl-3.1 http://jbpm.org/jpdl-3.1.xsd"
  |         name="jpgWorkflow">
  | 
  |     <start-state>
  |         <transition to="check gif"/>
  |     </start-state>
  | 
  |     <decision name="check gif">
  |         <handler class="com.amg.condenet.mediaflow.task.GifTypeDecisionHandler">
  |             <targetBean>sizeGifImageAction</targetBean>
  |             <factoryKey>jbpmConfiguration</factoryKey>
  |         </handler>
  |         <transition name="gif identified as anmiated" to="keyframe" />
  |         <transition name="gif identified as image" to="size gif" />
  |     </decision>
  | 
  |     <node name="size gif">
  |         <transition name="image sized" to="crop gif" />
  |     </node>
  | 
  |     <node name="crop gif">
  |         <transition name="image cropped" to="end" />
  |     </node>
  | 
  |     <node name="keyframe">
  |         <transition name="keyframe extracted" to="gif2swf conversion" />
  |     </node>
  | 
  |     <node name="gif2swf conversion">
  |         <transition name="gif2swf converted" to="end" />
  |     </node>
  | 
  |     <end-state name="end"/>
  | 
  | </process-definition>

This workflow gets deployed with no errors, but when I go to execute it, graphSession.findLatestProcessDefinition("gifWorkflow") returns null?  Is there a problem with the workflow definition?  My DecisionHandler looks like this:

public class GifTypeDecisionHandler implements DecisionHandler {
  |     
  | 
  |     private static Log log = LogFactory.getLog(GifTypeDecisionHandler.class);
  | 
  |     public String decide(ExecutionContext executionContext) throws Exception {
  |         log.info("********************************");
  |         log.info("*    GifTypeDecisionHandler    *");
  |         log.info("********************************");
  | 
  |         return "size gif";
  |     }
  | }
  | 

Right now, it's stubbed out, I simply trying to see if I'm defining a DecisionHandler properly for a 'decision' node.
