Hi,
when i am trying to run a servlet program ,it is showing the following error:

java.lang.ClassCastException: org.apache.catalina.connector.RequestFacade cannot be cast to javax.servlet.sip.SipServletRequest
javax.servlet.sip.SipServlet.service(SipServlet.java:99)

please help me to solve this problem.

Thanks

Without seeing the code that causes the error?

They both extend javax.servlet.ServletRequest, but that's about all you get.
