                                  javax.servlet.http.HttpServletResponse response,
                                  org.apache.struts.action.ActionForm form,
                                  org.apache.struts.action.ActionMapping mapping)

                                  org.apache.struts.action.InvalidCancelException

If this request was not cancelled, and the request's ActionMapping has not disabled validation, call the validate method of the specified ActionForm, and forward to the input path if there were any errors.

Throws:

java.io.IOException - if an input/output error occurs
