I want to create an m:n relationship between a User and Appointment.
XDoclet in User looks like this:
/** @ejb.bean name="User"
* description="An user with a container generated pk"
* display-name="User"
* jndi-name="ejb/User"
* local-jndi-name = "ejb/UserLocalHome"
* type="CMP"
* transaction-type="Container"
* cmp-version="2.x"
* view-type="local"
* @jboss.unknown-pk
* class="java.lang.Integer"
* column-name="pk"
* field-name="id"
* sql-type="INTEGER"
* jdbc-type="INTEGER"
* auto-increment="true"
* @jboss.entity-command
* name="hsqldb-fetch-key"
*
class="org.jboss.ejb.plugins.cmp.jdbc.keygen.JDBCHsqldbCreateCommand"
* @ejb.pk
* class="java.lang.Integer"
* generate="false"
and the get-ter for the field:
/**
* @return Collection of appointments.
* @ejb.interface-method view-type="local"
* @ejb.relation
* name="UserAppointment"
* role-name = "user-has-appointments"
* target-ejb = "Appointment"
* target-role-name = "appointment-has-users"
* target-multiple = "yes"
* @jboss.relation
* related-pk-field = "id"
* fk-column = "fk"
*/
public abstract java.util.Collection getAppointments();
XDoclet in Apointment looks like this (basically the same as in User):
/** @ejb.bean name="Appointment"
* description="An appointment with a container generated pk"
* display-name="Appointment"
* jndi-name="ejb/Appointment"
* type="CMP"
* transaction-type="Container"
* cmp-version="2.x"
* view-type="local"
* @jboss.unknown-pk
* class="java.lang.Integer"
* column-name="pk"
* field-name="id"
* sql-type="INTEGER"
* jdbc-type="INTEGER"
* auto-increment="true"
* @jboss.entity-command
* name="hsqldb-fetch-key"
*
class="org.jboss.ejb.plugins.cmp.jdbc.keygen.JDBCHsqldbCreateCommand"
* @ejb.pk
* class="java.lang.Integer"
* generate="false"
and the get-ter for the field (also basically the same as in User):
/**
* @return Collection of users.
* @ejb.interface-method view-type="local"
* @ejb.relation
* name = "UserAppointment"
* role-name = "appointment-has-users"
* target-ejb = "User"
* target-role-name = "user-has-appointments"
* target-multiple = "yes"
* @jboss.relation
* related-pk-field = "id"
* fk-column = "fk"
*/
public abstract java.util.Collection getUsers();
The relationship in the created jbosscmp-jdbc.xml looks ok to me:
<ejb-relation>
<ejb-relation-name>UserAppointment</ejb-relation-name>
<relation-table-mapping>
</relation-table-mapping>
<ejb-relationship-role>
<ejb-relationship-role-name>user-has-appointments</ejb-relationship-role-name>
<key-fields>
<key-field>
<field-name>id</field-name>
<column-name>pk</column-name>
</key-field>
</key-fields>
</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>appointment-has-users</ejb-relationship-role-name>
<key-fields>
<key-field>
<field-name>id</field-name>
<column-name>pk</column-name>
</key-field>
</key-fields>
</ejb-relationship-role>
</ejb-relation>
But still when I try to deplay with JBoss 4.0.4 I get following error:
org.jboss.deployment.DeploymentException: Both roles of a relation-table mapped
relationship must have key fields: ejb-relation-name=UserAppointment
Has anyone a hint?
Cheers, Jons.
