Simpletagsupport GET request, session

When developing JSP system, we often use tag to write Java logic code, generally inherit two classes, one is Simpletagsupport, the other is TagSupport, because TagSupport writing configuration is more complex (I personally caishuxueqian personally think),

The general adoption of inheritance Simpletagsupport when more.

There are pagecontext attributes in TagSupport to get Session,request objects, but only jspcontext in Simpletagsupport we convert the Jspcontext object to a PageContext object, and then you can invoke the Session,request object, such as:

HttpSession session= ((PageContext) This.getjspcontext ()). GetSession ();

HttpServletRequest request= (HttpServletRequest) ((PageContext) This.getjspcontext ()). Getrequest ();

If there are insufficient above please advise.
