    BindingResult result,HttpSession session,HttpServletRequest request) {
    if (result.hasErrors()) {
        System.out.println(result.toString());

I think the problem is in your controller function signature. You are validating on other object and your model attribute is another object. That is not the correct way to validate the object and show the errors on the form.

Your method signature should be as following.

public String findRide(@Valid @ModelAttribute("postAd") PostAdRR user,ModelMap model, BindingResult result,HttpSession session,HttpServletRequest request)

That is now you will bind the same object to the view which is you are validating.

Hope that helps you.

Cheers.

You can try annotating @NotNull along with @NotEmpty. Also is it possible to try @Valid in your controller before your model attribute. These are just guesses since you told the other page is working.

I am a bit wondering why the names in your excample does not match.

On one hand it is: contactName in <form:errors path="contactName" cssClass="Err"/> on the other it is: title

May this is the cause.

If this does not work try <form:errors path="*" cssClass="Err"/> (within the from) to show all error messages. The result of that test hopefully helps you to decide if the problem is in thw view or in the controll.er
