Hello,

I am deploying the war file in weblogic server and I am getting this error.


<Jan 27, 2003 11:59:17 AM IST> <Error> <HTTP> <[WebAppServletContext(6931479,Lis
tOfCustomer,/ListOfCustomer)] Servlet failed with Exception

The error indicates that it is throwing null pointer excepton in my servlet class because it is not able to create .jasper file . JRLoader is not able to load the file. Please let me know what would be the error. Is it in the xml file or anything else.

Thanx
Murli
