Hi I tried to implement the repository selectors.But still problems occurs.
Please find my repository selector below.
However i am not using Servlets to initialize the log4j.
So Even to implement repository selector i am not using servlets.
Our customers requested us to not use servlets.Since we made everything
using Java and jsps.

Can you please tell me whats wrong with the code.Is there any other way to
handle this?.
Thanks & Regards,

somewhat familiar with what they do.
