Thanks for your quick reply.
but i am surprised the same code is working on another server.
Actually i am moving the web server from another server where it is working
just fine.the only difference between this two configuration is on new
server i have tomcat 4.1.36 and jdk 1.6 and on running server tomcat 4.0 and
jdk 1.4.
I have copied all wwwroot files from running server to new server.
so i guess to doubt on test.jsp is not appropriate.
do you have any other clue for this.
Thanks for your interest in solving my problem.
Thanks,
Bharat
