[prash patil]

Hello Ranchers,
I am getting one Exception while accessing JSF page.

The scenario is
When I click on one link it passes some parameters in request..
On that click my jsf page get invoked. But I have added on CustomFacesServlet.java which gets invoked for
any jsf page request.

For some liks it gives following exception.

 javax.servlet.ServletException: org/apache/commons/collections/map/ReferenceMap

One thing which came in my mind is that id may be due to jars ... but not very sure.. :-(
Any suggesstion will be very helpful.
