I believe you should be using relation rather than target-relation.
target-relation is for uni-directional relationships where you
need to specify both sides of the relationship on one getter method.
Everything else looks ok to me. I am using m-n relationships with
JBoss 3.0.2 and xdoclet 1.1.2 and it is working ok. Here are
my xdoclet tags for an m-n relationship...
/**
*
* @ejb:relation
* name="Job-TechObject"
* role-name="TechObject-has-many-Jobs"
*
* @jboss:relation
* related-pk-field="id"
* fk-column="JobId"
*
* @jboss:relation-table
* table-name="Job_TechObject"
*
* @ejb:interface-method
*/
public abstract Collection getJobs();
/**
* Retrieve the Collection of TechObjects that the Job involves.
* For example, TechObjects to be inspected.
*
* @return Returns a Collection of TechObjectLocal (local interfaces
* to TechObjects) that this Job involves.
*
* @ejb:relation
* name="Job-TechObject"
* role-name="Job-involves-many-TechObjects"
*
* @ejb:interface-method
*
* @jboss:relation
* related-pk-field="id"
* fk-column="TechObjectId"
*
* @jboss:relation-table
* table-name="Job_TechObject"
*
**/
public abstract Collection getTechObjects();
Have a look at the xdcolet generated ejb-jar.xml and jbosscmp-jdbc.xml files
and make sure that xdoclet is generating what you expect.

Subject: [JBoss-user] M-N relationship error -xdoclet
Hello!
I am having problems while creating a M-N relationship using xdoclet. I am
using jboss3.0.0 with bundled Tomcat 4.0.3. I am also using xdoclet 1.1.2.
Do i need to get the latest xdcolet from CVS?
I am getting the following exception for both roles:
org.jboss.deployment.DeploymentException: Both roles of a relation-table
mapped relationship must have key fields: ejb-relation-name=User-Role
My xdoclet tags are:
UserBean:
#####
@ejb:relation name="User-Role"
role-name="User-Has-Many-Roles"
@jboss:relation-table table-name="xpto"
@jboss:target-relation related-pk-field="id"
fk-column="roleid"
#####
where "id" is the name of the primary key on the Role bean and "roleid" is
the name of the column in the relation table (xpto).
RoleBean:
#####
@ejb:relation name="User-Role"
role-name="Role-Has-Many-Users"
@jboss:relation-table table-name="xpto"
create-table="true"
remove-table="true"
@jboss:target-relation related-pk-field="id"
fk-column="userid"
#####
where "id" is the name of the primary key on the User bean and "userid" is
the name of the column in the relation table (xpto).
I have tried with "jboss:relation" instead of "jboss:target-relation" but
with the same results.
Can any one help me, please?
Thank you in advance,
Victor Batista
