CMP 2.0 EJB relationship problem

[amarpatel]

The relationship between the User entity and UserType etity is as follows:
1 User can only have 1 UserType, but 1 UserType can belong to many Users. Furthermore, User maintains a reference to UserType, but UserType does not have a reference to User. So in ejb-jar.xml, we have defined the one-to-many unidirectional relationship between the UserEJB and the UserTypeEJB is as follows:


<ejb-relation>
<ejb-relation-name>User-UserType</ejb-relation-name>
<ejb-relationship-role>
One
<relationship-role-source>
<ejb-name>UserTypeEJB</ejb-name>
</relationship-role-source>
</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>User-has-a-UserType</ejb-relationship-role-name>
Many
<relationship-role-source>
<ejb-name>UserEJB</ejb-name>
</relationship-role-source>
<cmr-field>
<cmr-field-name>userTypeLocal</cmr-field-name>
</cmr-field>
</ejb-relationship-role>
<ejb-relationship-role-name>UserType-has-many-Users</ejb-relationship-role-name>
</ejb-relation>



I have also added the following to jbosscmp-jdbc.xml:


<ejb-relation>
<ejb-relation-name>User-UserType</ejb-relation-name>
<foreign-key-mapping/>
<ejb-relationship-role>
<ejb-relationship-role-name>UserType-has-many-Users</ejb-relationship-role-name>
</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>User-has-a-UserType</ejb-relationship-role-name>
<fk-constraint>true</fk-constraint>
<key-fields>
<key-field>
<field-name>userTypeLocal</field-name>
<column-name>user_type_id</column-name>
</key-field>
</key-fields>
</ejb-relationship-role>
</ejb-relation>



However, when the inserting the above xml fragment into jbosscmp-jdbc.xml, I get an error saying that there is no ejb-relationship-tag-name element. I do not know the reason for this, as I have followed the dtd for jbosscmp-jdbc.xml, and confirmed that the ejb-relationship-role-name tags match in both jbosscmp-jdbc.xml and ejb-jar.xml.

Another modification I have tried is removing the relationships tag altogether from jbosscmp-jdbc.xml. This allowed me to deploy my beans. I also added the following cmp-field to the 'user' entity in jbosscmp-jdbc.xml:
<cmp-field>
<field-name>userTypeLocal</field-name>
<column-name>UTL</column-name>

<property-name>type</property-name>
<column-name>user_type</column-name>
<jdbc-type>VARCHAR</jdbc-type>
<sql-type>VARCHAR(20)</sql-type>

</cmp-field>
This xml fragment is in jbosscmp.xml. The result of this is that there is a field called utl in the user_types table in the database. But the value being inserted into this field is not the foreign key integer id of the user_types table, but a serialized version of the UserTypeEJB.

Please advise on the following issues described above:
1. no ejb-relationship-role-name defined error.
2. serialized UserType being stored in RDBMS table users, instead of foreign key integer.

Thank you.
