The definition of my query in ejb-jar.xml is follows:



Find Products by Name

<query-method>
<method-name>findByName</method-name>
<method-params>java.lang.String</method-params>
</query-method>
<result-type-mapping>Remote</result-type-mapping>
<ejb-ql>
SELECT OBJECT(p)
FROM MyProduct p
WHERE p.name = ?1
</ejb-ql>


The definition of the query in my home interface is as follows:

public Collection findByName(String name) throws FinderException, RemoteException;

I am using JBoss 3.0 and my bean is CMP. Any help would be appreciated.

I see two possible problems ...
1st, you are missing a tag in the descriptor
&lt;method-param&gt;

Should look like

&lt;method-params&gt; &lt;method-param&gt;java.lang.String&lt;/method-param&gt;
&lt;/method-params&gt;

Second if you are ussing Xdoclet (you really should!), class
names must be fully quialified names
like
java.lang.String
instead of
String
