HttpSession data to be cleared reg.

[gan chan]

We are using WebSphere App server & VAJava. We are accessing several content files(XML)and storing in the session data which is a HttpSession object. We would like to clear the session data. So as to retrieve new content changes.
Shutting Down WebSphere App. Server is a solution. But any alternative using a servlet or so. Please suggest us.

why would you need to do that? it clears when the session is over or maybe you can over-write it i do not know.

I wish there was a button on my monitor to turn up the intellegince.
Theres a button called 'brightness' but it doesn't work

Ganesh,
If you want to clear the whole session just use

      userSessionRef = HttpSession.getSession(false);
      userSessionRef.invalidate();
      userSessionRef = HttpSession.getSession(true);
    If you wany to clear just one value in HttpSession , then
    
      userSessionRef = HttpSession(false);
      userSessionRef.putValue("name",null);
                 OR
      userSessionRef.putValue("name",newValue);

Hi ganesh,
A little addition to what maha anna said.
Be sure to check for the null of userSessionRef variable before you call the invalidate() method. Because if the session does not already exist it would be null and a call to invalidate() method might throw up a null pointer exception.
my 2 cents worth
