and i am Writing a test class to test the service layer;

package com.dineshonjava.tester;

import java.util.ArrayList;

import java.util.Iterator;
import java.util.List;

import org.hibernate.SessionFactory;

import com.dineshonjava.model.Hobby;
import com.dineshonjava.model.Interest;
import com.dineshonjava.model.Profile;
import com.dineshonjava.model.User;
import com.dineshonjava.service.UserService;



public class ServiceTest {  

    private static SessionFactory sessionFactory;

    public static void main(String[] args) {        
        ClassPathXmlApplicationContext appContext = new ClassPathXmlApplicationContext(
                new String[] {"config/sdnext-servlet.xml"});        
        UserService userservice=(UserService)appContext.getBean("UserServiceImpl"); 

        List<Hobby> lsthobby=new ArrayList<Hobby>();
        List<Interest> lstinterest=new ArrayList<Interest>();   



        Profile p=new Profile();
        p.setAddress("fdsf");
        p.setiZip(11121);


        Hobby h1=new Hobby();
        h1.setsHobbyName("hobby1");
        h1.setsHobbyName("hobby2");

        Hobby h2=new Hobby();
        h2.setsHobbyName("hobby3");
        h2.setsHobbyName("hobby4");

        Interest int1=new Interest();
        int1.setsInterestName("interest1");
        int1.setsInterestName("interest2");

        lsthobby.add(h1);
        lsthobby.add(h2);
        lstinterest.add(int1);




        p.getLstHobby().add(h2);
        p.getLstHobby().add(h1);
        p.getLstInterest().add(int1);

        p.getLstHobby().add(h1);
        p.getLstHobby().add(h2);


        User user2=new User();
        user2.setsName("Prabhat2");
        user2.setsPass("prabhat4");
        user2.setoSingleProfile(p);


        Boolean ck=userservice.addUser(user2);

}
}

it is persisting the data in User and Profile but not in Hobby and Interest.

Please Help.

Thanks in advance.........

For *ToMany operations by default no cascade operations are executed. So if you want to persist or update the entries of the collections, you have to specify the cascade attribute of the annotation:

@OneToMany(cascade = CascadeType.ALL)

CascadeType.ALL will execute all operations on the collection (persist, update, delete etc.), but you can choose other CascadeTypes according to your requirements.
