JBoss and MySql auto increment deployment errors

[vidaest]

Hi, I have the following jbosscmp-jdbc.xml (created by jbuilder):

<jbosscmp-jdbc>
 <defaults>
 <datasource>java:/Projekt</datasource>
 <datasource-mapping>mySQL</datasource-mapping>
 <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>int(11)</sql-type>
 <auto-increment />
 </unknown-pk>
 <entity-command name="mysql-get-generated-keys" />
 </defaults>
 <enterprise-beans>
 <entity>
 <ejb-name>Person</ejb-name>
 ......
</jbosscmp-jdbc>

MySql is set up to auto increment id field in the table. But when I try to deploy the package, JBoss comes out with the following errors:

11:30:49,493 INFO [EntityContainer] Started jboss.j2ee:jndiName=Person,service=EJB

I wonder if anyone had similar problems. I would understand errors when creating/finding entities, but the null ptr exception comes out at deployment!

When I remove the unknown key/auto increment alltogether it works fine.

I don't know how/what JBuilder does its magic, I use Xdoclet.... Here's what Xdoclet generates for me for a CMP bean with 'auto-increment' for a primary key.

In jbosscmp-jdbc.xml (for bean BaseType with primary key baseTypeKey):

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

Hope that helps....
