Hello,
Can someone tell me, in case a null value, how I can use ActionErrors to
return an error to a jsp page and show a pop up to a user describing the error?
To send the error from your action:
public String execute(
HttpServletRequest request,
HttpServletResponse response) {
...
ActionErrors errors = new ActionErrors();
errors.add(new ActionMessage("key");
saveErrors(request, errors);
...
}
In your JSP, you'd render it using the <html:errors> or (preferred)
<html:messages> tags. Use one of those to inject the error message into
your popup Javascript or HTML markup.
