    org.hibernate.exception.DataException: could not initialize

    Ernest Molik Newbie

      My problem.
      I have two class Client and Book with relations OneToMany set on cascade "REMOVE".
      Now I must change scope "SESSION" on "CONVERSATION".
      Now (after the change) when i execute delete method on Client i have error. When scope is set on SESSION everything is ok but when is set on CONVERSATION then I have error. Why? PLEASE HELP!
      How it looks:

      Client CLASS

      package pl.test.client;
      
      import java.io.Serializable;
      import java.util.HashSet;
      import java.util.Set;

      import javax.persistence.Table;
      
      import org.jboss.seam.annotations.Name;
      
      @Entity
      @Name("client")
      @Table(name="clients")
      public class Client implements Serializable {
      
       /**
       *
       */
       private static final long serialVersionUID = -3074021688217036261L;
      
       private int id;
       private String name;
       private Set<Investment> books = new HashSet<Investment>();
      
       @Id @GeneratedValue
       public int getId() {
       return id;
       }
       public void setId(int id) {
       this.id = id;
       }
       @OneToMany(cascade=CascadeType.REMOVE, mappedBy="client")
       public Set<Investment> getBooks() {
       return books;
       }
       public void setBooks(Set<Investment> books) {
       this.books = books;
       }
       public String getName() {
       return name;
       }
       public void setName(String name) {
       this.name = name;
       }
      }
      


      Book CLASS

      @Entity
      @Name("book")
      @Table(name="books")
      public class Book implements Serializable{
      
       /**
       *

       private static final long serialVersionUID = 1624659788044987338L;
      
       private int id;
       private String bookname;
       private Client client;
      
       @JoinColumn(name="books")
       public String getBookname() {
       return bookname;
       }
       public void setBookname(String bookname) {
       this.bookname = bookname;
       }
       public Client getClient() {
       return client;
       }
       public void setClient(Client client) {
       this.client = client;
       }
       @Id
       @GeneratedValue
       public int getId() {
       return id;
       }
       public void setId(int id) {
       this.id = id;
       }
      }

                When I add "@Column(name = "client _id")" in Client class over

                public int getId() {return id;
                 }
                


                and in class Book "@ManyToOne, @JoinColumn(name = "grupaProd_id")" over

                public Client getClient() {
                 return client;
                 }
                


                problem disappear. Anyway thanks.

                  Mistake not "@JoinColumn(name = "grupaProd_id")" but "@JoinColumn(name = "client _id")".
