Hello Guys

I'm using Gilead to persist my entities in my GWT project, im using hibernate annotations aswell. my problem is on my onetomany association.this is my User class that holds a reference to a list of FileLocations

@Entity
@Table(name = "yf_user_table")
public class YFUser implements Serializable {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "user_id",nullable = false)
private int userId;
@Column(name = "username")
private String username;
@Column(name = "password")
private String password;
@Column(name = "email")
private String email;

@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY) @JoinColumn(name="USER_ID") private List fileLocations = new ArrayList();

This is my file location class

@Entity
@Table(name = "fileLocationTable")
public class FileLocation implements Serializable {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "locationId", updatable = false, nullable = false)
private int ieId;
@Column (name = "location")
private String location;

@ManyToOne(fetch=FetchType.LAZY) @JoinColumn(name="USER_ID", nullable=false) private YFUser uploadedUser;

When i persist this data in a normal desktop application, it works fine , creates the tables and i can add and store data to it. but when i try to persist the data in my gwt application i get errors i will show them lower. this is my ServiceImpl class that extends PersistentRemoteService.

public class TestServiceImpl extends PersistentRemoteService implements TestService {

public static final String SESSION_USER = "UserWithinSession";

public TestServiceImpl(){

    HibernateUtil util = new HibernateUtil();
        util.setSessionFactory(com.example.server.HibernateUtil
                .getSessionFactory());

    PersistentBeanManager pbm = new PersistentBeanManager();
    pbm.setPersistenceUtil(util);
    pbm.setProxyStore(new StatelessProxyStore());

    setBeanManager(pbm);
}

    @Override
public String registerUser(String username, String password, String email) {
    Session session = com.example.server.HibernateUtil.getSessionFactory().getCurrentSession();
    session.beginTransaction();

    YFUser newUser = new YFUser();
    newUser.setUsername(username);newUser.setPassword(password);newUser.setEmail(email);

    session.save(newUser);
    session.getTransaction().commit();

    return "Thank you For registering "+ username;

}

this is the error that im am getting. the error goes away when i remove my onetoManyRelationship and builds my session factory when i put it in , it on the line of buildsessionfactory in hibernate Util that it throws this exception. my hibernate util class is ok also. this is the error java.lang.NoSuchMethodError: javax.persistence.OneToMany.orphanRemoval()Z
