Subject RE: servlet.getServletContext().getAttribute("userList") is throwing NullPointerException in my sessionDestroyed() method
Date Mon, 11 Jun 2007 09:02:45 GMT
I'm with Guru on this one (theres a surprise for you).

I'd hate to see this list turn into a non-struts Webapp tutorial, can
someone point this guy at a good webapp tutorial and then just keep pointing
him at it until he reads it.

Guys,
	I think we are wasting our time here ... this thread has nothing to
do with struts in the first case ..... why are we trying to teach him when
he is not ok to get a good book and get his basics right .. 


I think he needs to read the spec first ... 
I think he lacks the basic understanding of how java works ( servlet in
particular ) works ..... 

You need to read the servlet specifications.. there is no way you can get 

Regards
Guru

The listener class is extending Action as well as implementing
HttpSessionListener interface.

Cant I have servlet in my sessionDestroy() method?

(Hashtable) servlet.getServletContext().getAttribute("userList");

As suggested by others the last time you asked this question, first try 
to determine whether it's the the servlet, servletContext or HashTable 
that's null.
HINT: Where did you get 'servlet' from in the sessionDestroyed() method?
