Why is this happening?

Hi there,
I have recently migrated to Tomcat 4.1.24. My application which used to work before is now not working. It gives the following error:
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: -1 in the jsp file: null

As you can see, my JSP page imports a Servlet. Does anybody know what's wrong. What is the 'fork' thing anyway?
Really appreciate any help.

Looks to me that the class dbpool is not the classpath.The JSP compiler is not able to find it.

I think Tomcat 4 changed the way classes are looked up and loaded. If your previous Tomcat was version 3, that may be the problem. As I recall the Tomcat 4 online documentation goes into this.

Thanks for the help guys. I think you are right William in your advice. I'm saying this because the app works fine in Tomcat 3.XXX. I'm off to read the Tomcat 4 manual now.

The 'fork thing' is an ant message. Look into the documentation on the ant javac task for information.
hth,
