Is the validate method being called?? Check if your action implements Validateable interface (the struts configuration is not of much use as we don't know the name of your action class)...

no validate method is not called
Action class:

public class LoginAction extends ActionSupport implements SessionAware

	/**

	private static final long serialVersionUID = 1L;
	
	private UserService userService;
	private List<User> userList;

private Map<String, Object> session;
	private User user= new User();

public List<User> getUserList() {
		return userList;

		return session;
	}

		this.session = session;
	}

		return userService;
	}

			return "success";
		}
		else
		{

hi rajiv..
Define result type 'input' in your struts.xml.

I think that will help..
Struts is redirecting your control to result type 'input'

please mention it inyour struts.xml

Thanks n Regards
Raza

Good luck!!
