Tomcat Configuration

Hi,
I am deploying a JSP but failed.
Http error 404 etc.
Tomcat does works.

So I suspect it is the environment variables setting up problem and I re-install tomcat pre-configuration version 6.0.10.

I tried to double click catalina.bat and setclasspath.bat in
%CATALINA_HOME%\bin.
However just see a window pop up then disappears quickly.the environment variables are unchanged at all.

OS: WIN XP HOME.
Jdk 1.6.0_04
J2EE 1.4
Can you please point it out what is wrong?

Thank you very much.

The correct one to start Tomcat is startup.bat. But don't double-click it; open a Concole window, change to the Tomcat directory, and then type "bin\startup.bat". That way you will see if there are any error messages.

I appreciate your reply but you may misunderstood my question.
bin/startup.bat is ok.
My question is I want to reset the environment variables by double
click bin\catalina.bat and bin\setclasspath.bat.
But they are not working.
I just saw a window jumps out then closes quickly. The environment variables are not set automatially.

Thanks
