XDoclet shortcoming?
Hello and merry christmas to everybody.
I'm using JBossIDE 2.0.0beta2.
The problem I am facing is with relations and the unknown-pk feature. I have two CMP EJBs:
package de.chitec.physio.server.ejb;
import java.rmi.RemoteException;
import java.util.Date;
import javax.ejb.EJBException;
import javax.ejb.EntityBean;
import javax.ejb.EntityContext;
import javax.ejb.RemoveException;
import org.apache.log4j.Logger;

* jndi-name="ejb/CMPPerson"
* type="CMP"
* cmp-version="2.x"
* view-type="local"
* reentrant = "false"
* local-jndi-name = "ejb/CMPPerson"
*
* @ejb.persistence
* table-name = "person"
*
* @ejb.pk
* class="java.lang.Object"
*
* @ejb.finder

* query="SELECT Object(o) FROM CMPPerson o WHERE o.lastName LIKE ?1"

As you can see both CMPs use automagically generated PKs. Now for the problem:
Both of the contained beans work well if not linked via a relation. As soon as the relation comes in we got a problem. I know how it is supposed to be done (using jbosscmp-jdbc.xml). The relation code should be:
<ejb-relation> <foreign-key-mapping/> <ejb-relation-name>Patient-To-Person</ejb-relation-name> <ejb-relationship-role> <ejb-relationship-role-name> Patient-To-Person-Role </ejb-relationship-role-name> <key-fields /> </ejb-relationship-role> <ejb-relationship-role> <ejb-relationship-role-name> Patient-Is-Person </ejb-relationship-role-name> </ejb-relationship-role> </ejb-relation>
The problem is: I simply don't know how to generate the
<foreign-key-mapping/>tag via xdoclet.
Please, please, please - help.... :-)
