Summary: CMR 1:n foreign key
Initial Comment:
Running on Win2K, JBoss-3.0.0beta2 CVSTag=HEAD
In a CMR 1:n (Order-LineItem from the docu), jboss
spits out an
org.jboss.deployment.DeploymentException: Role:
lineitem-belongsto-order with multiplicity many using
foreign-key mapping is not allowed to have key-
fields
With the following slice of jbosscmp-jdbc.xml:
<ejb-relation-name>Order-LineItem</ejb-relation-
name>
<foreign-key-mapping/>
<ejb-relationship-role>
<ejb-relationship-role-name>order-has-
lineitems</ejb-relationship-role-name>
</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>lineitem-
belongsto-order</ejb-relationship-role-name>
<key-fields>
<key-field>
<field-name>ordernumber</field-
name>
<column-name>ORDER_NUMBER</column-
name>
</key-field>
</key-fields>
</ejb-relationship-role>
</ejb-relation>
If I leave the <key-fields>-section, it tells me:
org.jboss.deployment.DeploymentException: At least one
role of a foreign-key mapped relationship must have
key fields: ejb-relation-name=Order-LineItem
