Thanks Peter for your reply. I agree there is a potential problem there by the relationship between stock and Produit is a One to One, so there are no collections there, but I have fixed the code . I am still getting the same exception with and if I set the fetch type to EAGER I get the following : | java.lang.reflect.UndeclaredThrowableException | at $Proxy0.selectAll(Unknown Source) | at com.elina.commercialis.client.delegate.stock.produit.ProduitDelegate.findAllProduits(ProduitDelegate.java:36) | at com.elina.commercialis.client.gui.model.stock.produit.ProduitTreeModel.initModel(ProduitTreeModel.java:38) | at com.elina.commercialis.client.gui.model.stock.produit.ProduitTreeModel.(ProduitTreeModel.java:29) | at com.elina.commercialis.client.gui.screens.stock.produit.ListProduitPane.initGui(ListProduitPane.java:39) | at com.elina.commercialis.client.gui.screens.stock.produit.ListProduitPane.(ListProduitPane.java:31) | at com.elina.commercialis.client.gui.screens.stock.produit.ProduitTab.initGui(ProduitTab.java:63) | at com.elina.commercialis.client.gui.screens.stock.produit.ProduitTab.(ProduitTab.java:51) | at com.elina.commercialis.client.gui.screens.stock.produit.MajProduit.(MajProduit.java:23) | at com.elina.commercialis.client.actions.stock.ProduitAction.showAdminFrane(ProduitAction.java:75) | at com.elina.commercialis.client.actions.stock.ProduitAction.access$0(ProduitAction.java:69) | at com.elina.commercialis.client.actions.stock.ProduitAction$1.run(ProduitAction.java:64) | at java.awt.event.InvocationEvent.dispatch(Unknown Source) | at java.awt.EventQueue.dispatchEvent(Unknown Source) | at java.awt.EventDispatchThread.pumpOneEventForHierarchy(Unknown Source) | at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) | at java.awt.EventDispatchThread.pumpEvents(Unknown Source) | at java.awt.EventDispatchThread.pumpEvents(Unknown Source) | at java.awt.EventDispatchThread.run(Unknown Source) | Caused by: java.rmi.MarshalException: Failed to communicate.

[JBoss-user] [EJB 3.0] - ManyToMany biderectional
Hi,
I am experiencing the now famous ManyToMany hiberante entity manager bug. I
have read the many post on the forum and tried the alternative : using Set
instead of collections, using Lazy Fetch type but none of that works for me.
The problem is as follow :
A product belongs to many Classes of Products
A Product belongs to many Famillies of Products
So, when creating a product, the product famillies and Classes can be selected.

Just a quick one ! How do I get localized error messages from JBoss ? For instance a deployement in a french speaking country would be more usefull with errors in french !

[JBoss-user] [Persistence & CMP/JBoss] - Re: MySQL 4/JBoss 3.2.3 and CMP 2.0
Hi,
Here is my primary key class :
public class ProductPK implements java.io.Serializable {
/*
* Note that the primary key fields must be a
* subset of the the container-managed Bean fields.
* The fields we are marking as container-managed in
* our Bean are productID, name, desc, and basePrice.
* Therefore our PK fields need to be from that set.
*/
public String productID;
public ProductPK(String productID) {
this.productID = productID;
}
public ProductPK() {
}
public String toString() {
return productID.toString();
}
public int hashCode()
{
return productID.hashCode();
}
public boolean equals(Object prod)
{
return ((ProductPK)prod).productID.equals(productID);
}
}
As you can see , it is a valid compound PK class.
For the querry, the only querry I could think of that would match the one in the
exception is the following from the ejb-jar.xml file :
findAllProducts
SELECT OBJECT (a) FROM ProductBean AS a WHERE a.productId IS NOT
NULL
The select clause does select Object (a)

Well, I don't have the exact exception at hand to post it , but basically the exception is about a SQL Exception ( check the my SQL manual etc..) that is thrown when the create method is called on the bean !
