      @Entity

      public class UserSite implements java.io.Serializable {

      private Users users;
      //...
      @ManyToOne(cascade = {}, fetch = FetchType.LAZY)
      @JoinColumn(name = "userId", unique = false, nullable = false, insertable = true, updatable = true)
      public Users getUsers() {
      return this.users;
      }

      public void setUsers(Users users) {
      this.users = users;
      }
      }

      any advise?
