How to exit from JSP page

[Deepak C S]

 Hi,

       Can anybody tell "how to exit from a JSP page? 

     I want to check for a condition at beginning of a JSP page and based on
result I want to skip processing rest of the JSP page....without using
big<If-else block>

   I mean I need a Perl  equivalent of "exit;" command in JSP.

thanx in advance,
Deeps
