ServletNotFoundException

Hi,

I'am on NW04s EP 7.0 SP14.I'am facing a problem in UWL.

When i click in attachments in UWL i'am getting this error

"404 Not Found

The request cannot be processed.

Details: com.sap.engine.services.servlets_jsp.server.exceptions.ServletNotFoundException: Requested resource [/irj/servlet] not found.

Exception id: [00144FFB4116006A0000001B0000155000046C5B0CC1978A]"

I suppose some jar files or some ear files are missing but i'am unable to get hold of exact point.

Anybody please guide me with a solution.

With Regards,

Pradeep.B
