Subject: servlets work but JSPs not!





hi,
I am a quite new user of Tomcat. I did set it up, but there seems to be a
simple problem. When I run the server and open the entrance page on the
browser(localhost:8080), i can view the servlet examples, that are given by
tomcat but the JSP Examples do not execute, server errors occur, and are
printed like:
----------------------------------------------------------------------------

how can I overcome this problem?
my SDK is version:1.4.0-rc
and JDK :1.1.8 (actually couldn't find the 1.2 one on sun`s webpage! can
this be causing the problem??)

waiting for your help,
thank you...
