URGENT.. org.apache.jasper.JasperException: Unable to compile class for JSP

[runu rathi <ru...@yahoo.com>]

Hi,
 I am having trouble running a simple application
which uses JSP and Beans.
 The error shown is
"org.apache.jasper.JasperException: Unable to compile
class for JSP". 
 The same application runs perfectly at another place
with exactly the same version of Tomcat..
Please see below for the exact error messages
obtained.
 I'll appreciate your help
Thankx
Runu

You probably have different Java VMs on each machine. AFAIK Java 1.4 no longer 
supports import of classes in the "root" package.
