Problem with finder emthod in EJB20

[ge_ha]

I have the following fider definition in the ejb-jar.xml File:


<ejb-name>EtmnUserRoleTab</ejb-name>
<local-home>etmn.db.EtmnUserRoleTabLocalHome</local-home>
etmn.db.EtmnUserRoleTabLocal
etmn.db.EtmnUserRoleTabHome
etmn.db.EtmnUserRoleTab
<ejb-class>etmn.db.EtmnUserRoleTabBean</ejb-class>
<persistence-type>Container</persistence-type>
<prim-key-class>java.lang.String</prim-key-class>
False
<abstract-schema-name>EtmnUserRoleTab</abstract-schema-name>
<cmp-version>2.x</cmp-version>
<cmp-field>
<field-name>userId</field-name>
</cmp-field>
<cmp-field>
<field-name>roleName</field-name>
</cmp-field>
<resource-ref>
<res-ref-name>OracleDS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>


<query-method>
<method-name>findAllRolesForUser</method-name>
<method-params>
<method-param>java.lang.String</method-param>
</method-params>
</query-method>
<ejb-ql>select object(p) from EtmnUserRoleTab p where p.userId = ?1</ejb-ql>



During deploying I get the following error from jboss 3.0 alpha:

You are missing the <primkey-field> tag which goes after the last <cmp-field> tag.

I have made a mistake in the ejb-jar.xml, because the prim-key-class is a class. here teh right code snipped.
But deployment does not work!


<ejb-name>EtmnUserRoleTab</ejb-name>
<local-home>etmn.db.EtmnUserRoleTabLocalHome</local-home>
etmn.db.EtmnUserRoleTabLocal
etmn.db.EtmnUserRoleTabHome
etmn.db.EtmnUserRoleTab
<ejb-class>etmn.db.EtmnUserRoleTabBean</ejb-class>
<persistence-type>Container</persistence-type>
<prim-key-class>etmn.db.EtmnUserRoleTabPK</prim-key-class>
False
<abstract-schema-name>EtmnUserRoleTab</abstract-schema-name>
<cmp-version>2.x</cmp-version>
<cmp-field>
<field-name>userId</field-name>
</cmp-field>
<cmp-field>
<field-name>roleName</field-name>
</cmp-field>
<resource-ref>
<res-ref-name>OracleDS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>


<query-method>
<method-name>findAllRolesForUser</method-name>
<method-params>
<method-param>java.lang.String</method-param>
</method-params>
</query-method>
<ejb-ql>select object(p) from EtmnUserRoleTab p where p.userId = ?1</ejb-ql>
