You can get the ReadOnlyProcessDefinition from RepositoryService (Cast to repositoryServiceImpl and call public ReadOnlyProcessDefinition getDeployedProcessDefinition(String processDefinitionId) {). Some fiddling around in the engine internals, but this is the only way to achieve this.

Then, based on the task-definition key (id in the XML), you can call something like this:


UserTaskActivityBehavior theTaskBehaviour = ((ActivityImpl)readOnlyProcesDefinition.findActivity("task1")).getActivityBehavior();
TaskFormHandler taskFormHandler = theTaskBehaviour.getTaskDefinition().getTaskFormHandler();
      if (taskFormHandler == null) {
        throw new ActivitiException("No taskFormHandler specified for task '" + taskId +"'");
      }
      
      return taskFormHandler.createTaskForm(task);

Another way is going through the RepositoryService and retrieve the BpmnModel. That gives you a pojo representation of your process.
