Hi,

I had the same problem today and I haven't found a way to resolve it.
I think that the only way to get it is getting and parsing the XML process file but I'm not sure.
I can't get task definition using the API.

thanks dognose!

If someone need the code to get the taskDefinitions from the process definition, the snippet below works fine:
(the only one difference from dognose code, is using PvmActivity instead of ActivityImpl)


 ReadOnlyProcessDefinition processDefinition = 
   ((RepositoryServiceImpl)repositoryService)
   .getDeployedProcessDefinition( procDef );

 if (processDefinition != null) {
       for (PvmActivity activity : processDefinition.getActivities()) {
         String type = (String) activity.getProperty("type");
         System.out.println( type + ":  " + activity.getProperty("name"));
         // …
       }

type could be userTask, exclusiveGateway, endEvent and so on… and name will be the name of the element in the bpm diagram..
