Hi
You are simply trying to set a null value in a session, which is
forbidden.something like session.setAttribute(HelloWorld, null);
I'm not sure this behaviour is specified in JSP specs though
it's more because a Hashtable is used as the Map to store key=value session
attributes within
or there is a bug in
Tomcat3.3.

The Servlet 2.2 spec states that neither the name or
object may be null. This is the spec that Tomcat 3.3 is the
reference implementation for.
The Servlet 2.3 spec allows the object
is actually null.
Hope this helps.
Cheers,
Larry

In Jdk 1.3.1, line 380 is where java.util.Hashtable.put()
throws an NPE after testing the value for null. In
ServerSession.setAttribute(), other than logging, there
is only attributes.put(name, value);.
At this point, I think it is more likely
Have a look at
com.fub.its.servlet.SecuredServlet Line 162
That's where the NullPointer comes from.
