the xsp session stuff

[Jon Brisbin <br...@ipa.net>]

I'm having trouble using the XSP session objects.  It appears that there is
no checking to handle the first use of a session, when none exists yet.  If
I try to access anything with the session object, I get a
NullPointerException.  Where do I need to edit my code to have it do a
getSession(true) so it will create a session to use??

Thanks!

hi,

<xsp:page

    ...
    create-session="true"

if memory serves me, I'm sure someone will correct me if this isn't correct.

You could do the following:

HttpSession mySession = request.getSession(false);


This will get you the Session-Object if a valid session is there somewhere 
around :-)
Else "mySession" is null.

So if you try to access the session-object you shoul check if it is null or 
nor:

if(mySession!=null){
         // Do something
}else{
         // Do something
}
