any suggestion working without removing code of xml file ?

thanks in advance guys.

one reason problem problems in web.xml file...

i got problem, resolved it.

step resolve problem:

1- check every servlet class name correct(fully qualified class name )

2- checking correct class name go on class name press ctrl , move pointer on class name if class name giving hyperlink class name correct otherwise have change appropriate class name.

3- check jar added in project correct , working

4- after changes refresh project , run it..

it works....
