[OT] RE: how to get servletContext from httpsession ? (servlet ap i 2.2)

You can use HttpServlet.getServletContext()

... or if you are in a jsp/tag, PageContext.getServletContext()

Subject: how to get servletContext from httpsession ? (servlet api 2.2)


Hi,
 My webapp use HttpSession.getServletContext() method
and works fine on tomcat 4.x. but not in websphere
4.x.
I just figure out HttpSession.getServletContext()
method is only avilable on servlet api 2.3.
 So in api 2.2, how can I do similar things? What I
need is in valueBound(HttpSessionBindingEvent se)
method to get an attribute from the application scope.
 With api 2.3, this seems so easy, but api 2.2 confuse
me. 
 
 Thanks.
David

Re: [OT] RE: how to get servletContext from httpsession ? (servlet ap i 2.2)

Posted by david chan <da...@yahoo.com>.
My problem is I have a class implements
HttpSessionBindingListener, then in method valueBound
and valueUnBound(HttpSessionBindingEvent se), I need
to access servletContext, but can't found a way to get
there.
I know from Action class/JSP/Servlet, I can get
servletContext.

What I trying to do is everytime a session expired or
invalidated, I need to do a clearup of this session
related data in a Hashtable stored in application
scope.

I already implemented in servlet api 2.3, but just
found out can't deploy to websphere 4.x because it
only supports api 2.2.

Thanks.
David
