Superclass for JSPs?

["Felix A. Milovanov" <fe...@terasystems.com>]

  Hello all,

  i just started using Java for server-side WEB development ( I've 4 years of
this development in C and Perl ). When I read about JSPs, I found than JSP is
compiled into servlet on a first call and than runs like a servlet. 

  The question is : is it possible to have a superclass for my JSPs? I need to
make some activity before each JSP is called. I made a superclass for my 
servlets, so I cat write my servlets inherited from baseServlet and do not worry
about pre-request activity. But how can I do it for JSP???

  Sincerely,

									Felix.

I honestly don't know if it's possible to subclass
your JSP pages, but I may have a hack workaround. 
First, know that you can declare a 'jspinit()' method
that is just like the 'init()' method in your servlet.
 Search the following doc for details:

http://developer.java.sun.com/developer/onlineTraining/JSPIntro/contents.html

Also, you might use the 'include' directive to include
a jsp file in all of your other jsp pages.  For
instance, you may write a 'init_and_utils.jsp' file
and use the jsp include directive to attach it to each
of your other jsp's.

<jsp:include page="init_and_utils.jsp"/>
