validate method...
Hi Alan,
Here are the basics:
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception {
ActionErrors errors;
ActionError error;
//create the errors
errors = new ActionErrors();
... do your validation, and if error
//create the error
error = new ActionError(error.resource.key);
//add it to the errors (global or form field name based) this
uses global
errors.add(ActionErrors.GLOBAL_ERROR, error);
...perform rest of method
if (errors.isEmpty() == false) {
//save the error
saveErrors(request, errors);
//go back to same page
return mapping.getInputForward();
}
// Forward control to the specified success URI
return (mapping.findForward(success));
}
Hope this helps.
Chuck

Subject: setting an ActionErrors object for a form outside a validate
method...
My Action class does some processing that involves going to the
database. This work could throw a SQLException and I want that to
generate an error message for the user. However I don't want to do this
work in the validate method, only to have to do it again in the execute
method (besides SQLExceptions can be non-determinate so this wouldn't
solve the problem anyway).
So, my question is how can I add an ActionErrors object to my form from
within the execute method so I can send the user back to their
requesting page with an intelligent and well formatted message?
Thanks,
alan
