Problem with mapping strategy

Tomasz Mazan Wed, 02 Jan 2008 13:31:43 -0800

Hello

I use openjpa 1.0.0 with Geronimo 2.0.2 and got strange exception forapplication.


There's 3 classes

1) Customer

@Entity @Table(name = "customer")
public class Customer implements Serializable {
..

@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER,mappedBy="customer")private Set<BillingAccount> billingAccounts = newHashSet<BillingAccount>();

..
}


2) BillingAccount

@Entity @Table(name = "billing_account")
public class BillingAccount implements Serializable {
..

@ManyToOne(cascade = {CascadeType.MERGE, CascadeType.REFRESH}, fetch= FetchType.EAGER)

   @JoinColumn(name = "customer_id", nullable = false)
   private Customer customer;

   @Column(name = "status", nullable = false) @Basic
   private BillingAccountStatus status; //enumeration

@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER,mappedBy = "billingAccount")

   private Set<Product> products = new HashSet<Product>();
..
}

3) Product

@Entity @Table(name = "pstn_account", uniqueConstraints =[EMAIL PROTECTED](columnNames = {"device_identifier", "line"})})

public class Product implements Serializable {
..

@ManyToOne(cascade = {CascadeType.MERGE, CascadeType.REFRESH}, fetch= FetchType.EAGER)@JoinColumn(name = "billacc_id", nullable = false)private BillingAccount billingAccount;


   @Column(name = "status", nullable = false) @Basic @XmlElement
   private ProductStatus status;

@OneToOne(cascade = CascadeType.ALL, fetch = FetchType.EAGER,mappedBy = "product")

   private VoiceMail voiceMail;

//START OF SPECIAL BLOCK

private void changeStatus(ProductStatus newStatus) throwsEntityAttributeException {


       switch (newStatus) {
           case NEW:
               throw new EntityAttributeException("Message 1");

           case DELETED:
               throw new EntityAttributeException("Another message");

           case ACTIVE:
               //START OF STRANGE BLOCK

if(!this.billingAccount.getStatus().equals(BillingAccountStatus.ACTIVE)) {throw new EntityAttributeException("Invalid Accountstatus");

               }
               //END OF STRANGE BLOCK
...
           case default:
               throw new EntityAttributeException("Unexpected change");
//END OF SPECIAL BLOCK
..
}

-------------------------------------------------------

My DAO layer (basen on session bean) uses EntityManager to find_Customer_ object. Code of changeStatus is not explicitly ivoked in my code.

When I try to find customer using any criteria I get two kinds of exception.

1st for code with commented STRANGE BLOCK in Product class:
