Hi, I've got a bunch of CMPs (running on JBoss 3.2.5) representing an order
with orderLine. Here are the links:
Order -1----*-> OrderLine -1----1-> Item
|
V
Customer
My problem comes when I want to create an order. With existing Customer and
Items, I want to create (in one go) an Order with its OrderLines. When I do
that I've got the following exception
15:53:01,187 ERROR [LogInterceptor] TransactionRolledbackException in method:

I've localised the problem but I can't solve it or explain it. It's in the
postCreate of the OrderLine CMP when it calls the setOrder method. If I take it
our, the exception doesn't occur but in the database I've got a foreign key set
to null, normal.
public String ejbCreate(int quantity, double unitCost, OrderLocal order,
ItemLocal item) throws CreateException, CheckException {
|
| setId(getUniqueId(COUNTER_NAME));
| setUnitCost(unitCost);
| setQuantity(quantity);
| return null;
| }
|
| public void ejbPostCreate(int quantity, double unitCost, OrderLocal
order, ItemLocal item) throws CreateException, CheckException {
|
| setOrder(order);
| setItem(item);
| }
The method setOrder IS a CMR Method and it's declared abstract like all the
other getters and setters
public abstract int getQuantity();
| public abstract void setQuantity(final int quantity);
|
| public abstract double getUnitCost();
| public abstract void setUnitCost(final double unitCost);
|
| public abstract OrderLocal getOrder();
| public abstract void setOrder(final OrderLocal order);
|
| public abstract ItemLocal getItem();
| public abstract void setItem(final ItemLocal item);
And here are bits of the ejb-jar.xml
<entity>
| <display-name>OrderEB</display-name>
| <ejb-name>OrderBean</ejb-name>
|
<local-home>com.yaps.petstore.server.domain.order.OrderLocalHome</local-home>
| <local>com.yaps.petstore.server.domain.order.OrderLocal</local>
|

| </cmp-field>
| <cmp-field>
| <field-name>unitCost</field-name>
| </cmp-field>
| <primkey-field>id</primkey-field>
| </entity>
And the relationship part
<ejb-relation>
| <ejb-relation-name>OrderBean - OrderLineBean</ejb-relation-name>
| <ejb-relationship-role>
|
<ejb-relationship-role-name>order-has-orderLines</ejb-relationship-role-name>
| <multiplicity>One</multiplicity>
| <relationship-role-source>
| <ejb-name>OrderBean</ejb-name>
| </relationship-role-source>
| <cmr-field>
| <cmr-field-name>orderLines</cmr-field-name>
| <cmr-field-type>java.util.Collection</cmr-field-type>
| </cmr-field>
| </ejb-relationship-role>
|
| <ejb-relationship-role>
|
<ejb-relationship-role-name>orderLine-belongs_to-order</ejb-relationship-role-name>
| <multiplicity>Many</multiplicity>
| <relationship-role-source>
| <ejb-name>OrderLineBean</ejb-name>
| </relationship-role-source>
| </ejb-relationship-role>
| </ejb-relation>
Does anybody have an idea, I've been looking everywhere and can't find any
solution.
Thanks in advance
Antonio
