Hi,
It was great to recieve such a promt reply.
Thanks a lot.
But the problem remains unsolved.
I have added commons-logging.jar file to the System classpath through the enviorenment variables. (Working on Windows 2000 professional)

Still it does not help.
Its really bad to have no results after trying all possibilities.
The exact error is :

java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory at

It would be of great if you could help.
Thanks,
Sayali.
