16  * When WebWorkPortlet doService() include the JSP resource, then
17  * WebWorkJSPServlet was invoked.
18  * <p/>
19  * Now we can use WebWorkJSPServlet to render the result JSP with the stackValue
20  * stored in ActionContext after WebWork Action was executed.
21  * <p/>
22  * Because PortletRequestDispatcher include() method in WebWorkPortlet
23  * doService() can not filtered by ServletFilter, we must add the SiteMesh
24  * function here if want SiteMesh decoration support.
