DFS custom WSDL configuration

Hi Experts,

We have recently customised ObjectService class and created new WSDL through Eclipse and defined in the web.xml of DFS.But, while trying to call that WSDL file URL we are facing "404 Not Found: Invalid Request" error .

Can anyone guide us whether there is any additional configuration to be done apart from web.xml.

Also, we created jar for the newly created class file and deployed in lib.
