You can do one more things.the validation you can do in action itself. I am attaching some code here. just change your action mapping some what it would work
import javax.servlet.http.*;
import org.apache.struts.action.*;
public class ExampleAction extends org.apache.struts.action.Action {
/* forward name="success" path="" */
private static final
String SUCCESS = "success";
/* failure name="failure" path="" */
private static final String FAILURE = "failure";
@Override
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
//Add error into incoming HTTP request
ActionMessages errors = new ActionMessages();
// By making instance of DynaActionForm class,
DynaActionForm actionForm = (DynaActionForm) form;
//Value store into DynaForm is call here:
String first = (String) actionForm.get("first");
String last = (String) actionForm.get("last");
int age = (Integer) actionForm.get("age");
int number = (Integer) actionForm.get("number");
//Check the valiadation condition into incomming HTTP request form DynaForm
if (first == null || first.length() < 1) {
errors.add("first", new ActionMessage("error.first.required"));
}
if (last == null || last.length() < 1) {
errors.add("last", new ActionMessage("error.last.required"));
}
if (age == 0) {
errors.add("age", new ActionMessage("error.age.required"));
}
if (number < 1) {
errors.add("number", new ActionMessage("error.number.required"));
}
//Save Error/request and dispaly it anywhere within this application
saveErrors(request, errors);
if (errors.isEmpty()) {
return mapping.findForward(SUCCESS);
} else {
return mapping.findForward(FAILURE);
}
}
}
