validation in spring

[Ashimashi Kabashi]

how does one show a validation error messages in spring one uses a jstl/core taglib
for example

    
   <spring:bind path="name">
     <input type="text" name="${status.expression}" value="${status.value}"/>
      <span class="error"><c :-o	 ut value="${status.errorMessage}" /></span>
    </spring:bind>

now the problem is that my app server throws an exception

    
According to TLD or attribute directive in tag file, attribute value does not accept any expressions

so I take that you cant do this <c ut value="${status.errorMessage}" />?

Why do you even need the core out tag? Just use ${status.errorMessage} without it.

its not working ... the form in not being submitted meaning the validation has executed but the error message does not show up.
this is my jsp

    
  <spring:bind path="name">
    <input type="text" name="${status.expression}" value="${status.value}"/>
      ${status.errorMessage}
  </spring:bind>

This is my validation code

    
public class LoginValidator implements Validator {
 
    public void validate(Object obj, Errors errors) {
        Login login = (Login) obj;
        if(login.getName() == null || login.getName().length() == 0)
            errors.rejectValue("name", "required", "");
    }
 
    public boolean supports(Class arg0) {
        return arg0.isAssignableFrom(Login.class);
    }
}
