I have a simple User model whose fields are annotated with play validation annotations and morphia annotations like below.

import play.data.validation.*;
import play.modules.morphia.Model;
import com.google.code.morphia.annotations.*;

@Entity
public class User extends Model{

    @Id
    @Indexed(name="USERID", unique=true)
    public ObjectId userId;

    @Required public String userName;


    @Email
    @Indexed(name="USEREMAIL", unique=true) 
    @Required public String userEmail;  
}

Now I have a service which has a CreateNewUser method responsible for persisting the data. I have used Morphia plugin for the dao support. But the problem is that User Document gets persisted in mongo-db even if userName or userEmail is NULL. Also @Email validation does not happen

// Below code is in app/controllers/Application.java
User a = new User();
a.userName = "user1";
// calling bean to create user, userService is in app/service/UserService
userService.createNewUser(a);

It does not work even after adding @valid and validation.hasErrors() check.Below code is in app/service/UserService

public void createNewUser(@Valid User user) {
        if (Validation.hasErrors()) {
              System.out.println("has errors");
            }   else {
            // TODO Auto-generated method stub
              userDao.save(user);
        }
}
