brokenweblogic-cmp-rdbms-jar.xml

I've been trying to describe a 1:n relationship from a customer to the
customer's addresses with the following tags:
* @ejb:interface-method view-type="local"
* @ejb:relation
* name="addresses"
* role-name="one-customer-has-many-addresses"
* target-ejb="AddressBean"
* target-role-name="one-address-belongs-to-one-customer"
*
* @weblogic:relation
* target-foreign-key-column="customer_id"
* key-column="id"
*
In XDoclet 1.1.1 this generates the following code
in weblogic-cmp-rdbms-jar.xml:
<weblogic-rdbms-relation>
<relation-name>addresses</relation-name>
<weblogic-relationship-role>
<relationship-role-name>one-customer-has-many-addresses</relationship-role-name>
<column-map>
<foreign-key-column>customer_id</foreign-key-column>
<key-column>id</key-column>
</column-map>
</weblogic-relationship-role>
</weblogic-rdbms-relation>
That is wrong because all relationships must have two
<weblogic-relationship-role>:s. The correct xml would be:
<aslak>
No, it's not wrong. Check the DTD (it's bundled with xdoclet). Only m:n relationships
are supposed to have two <weblogic-relationship-role>:s.
It looks as though you're trying to define a unidirectional 1:n relationship. If
you're trying to define a bidirectional relationship, you should not specify the
target-xxx parameters, but define the relationship in each of the two methods in the
relation. -If you're trying to define a unidirectional one everything looks ok.
Please see the docs for @ejb:relation and @weblogic:relation for further info.
</aslak>
<weblogic-rdbms-relation>
<relation-name>addresses</relation-name>
<weblogic-relationship-role>
<relationship-role-name>one-address-belongs-to-one-customer</relationship-role-name>
</weblogic-relationship-role>
<weblogic-relationship-role>
<relationship-role-name>one-customer-has-many-addresses</relationship-role-name>
<column-map>
<foreign-key-column>customer_id</foreign-key-column>
<key-column>id</key-column>
</column-map>
</weblogic-relationship-role>
</weblogic-rdbms-relation>
Am I doing something wrong or is this a bug?
<aslak>
At first glance it looks ok to me. Do you get an ejbc error? If you do, please post
the error message.
