error on running jsp

[Hari <ha...@hotmail.com>]

Hello,
I am getting the following error on opening a jsp page in tomcat.
I have installed Apache/1.3.12 in win NT. It was working fine when i was
working with jdk1.2.2. I have installed jdk1.3 now and it is not working.  I
have changed the classpath variables to point it to jdk1.3
could you please let me know where the problem is.
Thank you.
