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.
