I am using Tomcat 4.1.29

I have a bodytag called Page

In the constructor of this Tag I do this:

   HttpSession session = null;
   
   try
   {
     session = pageContext.getSession();
   }
   catch(Exception ex)
   {
     ex.printStackTrace();
   }

When I use this tag on a JSP page and try to access this jsp page, I
get the following:

If I comment this line: // HttpSession session =
pageContext.getSession(); in the Page tag constructor everything works
fine.

How do I get the session in the tags constructor? why am i getting the
exception? Any Ideas?

Regards
