I have a main process which contains a sub process like following images.

the sub-process image is like following:

the "Get mode Price "task will bing to customized WorkItemHandler.

the WorkItemHandler codes roughly like

public class PriceModelHandler implements WorkItemHandler {
  @Override
          public void abortWorkItem(WorkItem arg0, WorkItemManager arg1) {
                    // TODO Auto-generated method stub  
          }
          @Override
          public void executeWorkItem(WorkItem w, WorkItemManager m) {
                    String modelNumber = (String)w.getParameter("modelNumber");   

   //????
*    kcontext.setVariable("price",123);*

    //???? get an object like kcontext in order to call setVariable("variable",valeu);

                    m.completeWorkItem(w.getId(), null);
          }
}

my question is how to get an object like kcontext in executeWorkItem method in order to call setVariable to save the variable value for later use by 
other tasks following.
