Processes the action providing default error handling. Implementation should override this method to provide
their own error handling if the default is not to be used.

@param     mapping  The ActionMapping used to select this instance
@param     form     The optional ActionForm bean for this request (if any)
@param     request  The HTTP request.
@param     response The HTTP response.

@return    A struts forward to tell struts where to go after this action.

@exception IOException      If an input/output error occurs.
@exception ServletException If a servlet exception occurs.
