Re: session.invalidate() throws exception.

2003-12-11 Thread Antony Paul 
Did you tried the code given in previous post. Here two samples are given.
You try it.
This throws nullpointer exception
%@ taglib uri=/WEB-INF/struts-html.tld prefix=html%
%session.invalidate();%
html:form action=/LoginAction
/html:form

But this one wont throw any exceptions.
%@ taglib uri=/WEB-INF/struts-html.tld prefix=html%
%session.invalidate();%

I am working on porting a project to Struts. This error happened when I
copied contents of the old index.jsp to new Struts index.jsp. The error is
due to html tag.

 so you call invalidate()
 Causes this representation of the session to be invalidated and removed
from
 its context.
 then you call get on the invalidated session..
 Reminds me of the construction worker who said no matter how many times I
 cut this it's still too short..
 Think about it..

RE: session.invalidate() throws exception.

2003-12-10 Thread Milind Kulkarni 
It seems that your session is getting killed when you navigate to another
site and subsequently when you try to invalidate the session it is giving an
error since session is already killed. May be you should check for the
existence of session and then if the session exists then only try to
invalidate the session.

How to change this behavior. Better if possible to do some house
 keeping
before invalidating session like if a valid session and data is
 present
  in
  
session then go to a certain page.

RE: session.invalidate() throws exception.

2003-12-10 Thread Trieu, Danny 
Usually, it is a bad idea to do these thing inside a JSP(or View).  Front
Controller is where you want to do all these tuff.  Sure, you can query the
session object before you invalidate its or just try/catch
IlligalStateException and ignore it.

Re: session.invalidate() throws exception.

2003-12-10 Thread Martin Gainty 
so you call invalidate()
Causes this representation of the session to be invalidated and removed from
its context.
then you call get on the invalidated session..
Reminds me of the construction worker who said no matter how many times I
cut this it's still too short..
Think about it..

   Then index.jsp is to be mapped to an action in web.xml. My situation
is
  user
   goes to another site then returns to home page of our application.

Hello Antony
   
Here is a sample of code, hopes this solves your problem...
   
public ActionForward execute(ActionMapping mapping,
 ActionForm form,
 HttpServletRequest request,
 HttpServletResponse response)
throws
Exception {
   
// Extract attributes and/or parameters we will need
Locale locale = getLocale(request);
MessageResources messages = getResources(request);
HttpSession session = request.getSession();
   
// Get already logged user info from session scope // 
We
  have
   a
Customer Bean in session
Customer customer =
(Customer)session.getAttribute(USER_KEY);
   
// If customer has not logged in, return control to User
Login
   view
with
// that reason.
if (customer == null) {
return new ActionForward(/Login.do?reason= +
LOGIN_REASON_NOT_LOGGED_IN, true);
}
}
