unable to compile class for jsp

[moo moo farm gal]

Hi all,
I just installed Tomcat 4.1.27 and JDK 1.4 on a WIN2K server. But it doesn't work and kept on telling me it can't compile jsp files. I checked the environment variables and path , and they're pointing to the correct directory, so i'm kinda puzzled why it can't compile

The error starts here...any help appreciated.

Are you able to see the normal Tomcat startup screen? How about the JSP examples?
IMPORTANT NOTE: Tomcat pays no attention to the Environment classpath.

what are the environment variables, what is their exact case, and what do they point to ?
