This exception comes when the Response Object has already been inititiated in your JSP.
while using the Include Action directive, response object should be first sent to this Included "ErrorDetails.do" page. You must be modified the response object before calling this "ErrorDetails.do" page.
& hence the error is that Response is already committed....
