Here I am explaining how to use dyna action and how to do date validation in struts.
DynaDateAction
package com.DynaAction.DateValidation;
import org.apache.struts.action.*;
import org.apache.struts.validator.DynaValidatorForm;
import javax.servlet.http.*;
import java.util.*;
public class DynaDateAction extends Action{
public ActionForward execute(ActionMapping map,ActionForm form,HttpServletRequest req,HttpServletResponse res)throws Exception
{
DynaValidatorForm login=(DynaValidatorForm)form;
String na=(String)login.get("name");
String da= (String) login.get("date");
req.setAttribute("n1",na);
req.setAttribute("p1",da);
return map.findForward("success");
}
}
ApplicationResources.properties
errors.ioException=I/O exception rendering error messages: {0}
error.database.missing=<li>User database is missing, cannot validate logon credentials</li>
errors.required={0} is required.
errors.minlength={0} can not be less than {1} characters.
errors.maxlength={0} can not be greater than {1} characters.
errors.invalid={0} is invalid.
errors.byte={0} must be an byte.
errors.short={0} must be an short.
errors.integer={0} must be an integer.
