I am configuring jbosscmp-jdbc.xml to support for unknown-pk and I am having difficulties with it. I have two ejbs which are related through CMR. One of them has a known PK while the other has unknown-pk. After doing some research on the web, I have come up with the following snippet in the jbosscmp-jdbc.xml:

<unknown-pk>
<unknown-pk-class>java.lang.Integer</unknown-pk-class>
<field-name>id</field-name>
<column-name>id</column-name>
<jdbc-type>INTEGER</jdbc-type>
<sql-type>INTEGER</sql-type>
<auto-increment/>
</unknown-pk>
<entity-command name="get-generated-keys"
class="org.jboss.ejb.plugins.cmp.jdbc.keygen.JDBC30GeneratedKeysCreateCommand"/>

This is within the tag.

When one of the EJBs goes to create the other EJB I get the following exception:

2003-10-06 11:56:26,447 ERROR [org.jboss.ejb.plugins.cmp.jdbc.JDBCCreateEntityCommand.AddressBean] Could not create entity

I am currently using firebird driver pointing to an interbase database.

Could somebody help me out?
