With JBoss 3.0.4 and

My (ejb-jar, not everything, let me know if it is not enough):

<prim-key-class>java.lang.String</prim-key-class>
False
<cmp-version>2.x</cmp-version>
<abstract-schema-name>customer</abstract-schema-name>
<cmp-field>
<field-name>name</field-name>
</cmp-field>
<cmp-field>
<field-name>fullname</field-name>
</cmp-field>
<cmp-field>
<field-name>idno</field-name>
</cmp-field>
<primkey-field>name</primkey-field>

<query-method>
<method-name>findByIdno</method-name>
<method-params>
<method-param>java.lang.String</method-param>
</method-params>
</query-method>
<ejb-ql><![CDATA[SELECT OBJECT(o) FROM customer AS o WHERE o.idno = ?1]]></ejb-ql>



My (CustomerLocalHome extends EJBLocalHome):

public CustomerLocal findByIdno(String idno) throws FinderException;

My code:

CustomerLocal customer = customerHome.findByIdno(idno);

I get this error:
