finder method

I am using Orion2.0 App server.I used CMP entitybeans.I have written one finder method
My code is like this
1) in TestUserHome home interface of entity beans
public Collection findByFirstName(String firstName)throws FinderException , RemoteException;
2) in ejb-jar.xml
<!------ And more other -->
SELECT OBJECT(u) FROM TestUser AS u WHERE u.firstName=?1

3) I am calling the finder method from session bean as
///////Other required stuff here
Collection testUsers =testUserHome.findByFirstName(name);
////////other stuff

And when i execute the application then it gets all the records regardless of the finding by the passed name
But when i do entry in server specific orion-ejb-jar.xml as

<entity-deployment name="TestUser" location="TestUser" wrapper="TestUserHome_EntityHomeWrapper2"
table="TestUser" data-source="jdbc/MyDS" isolation="uncommitted" max-tx-retries="2">
<finder-method query="$firstName = $1">

but both cases i get one warning when i start my server as
WARNING: Unused <query> tag found in <entity> 'TestUser', method name 'findByFirstName(java.lang.String)'

Hi there

I never worked with orion, so I just have to guess: Is there some kind of 'orion-cmp-rdbms-jar.xml' that maps the cmp-fields to real database fields? In WebLogic I have such thing and there I also have to register my finder methods. Have a look in your docu for 'cmp-rdbms', hope this helps.

There is no any config file such like 'orion-cmp-rdbms-jar.xml'
And already i have mapped all the cmp fields in deployment descriptor.
THE APPLICATION IS WORKING FINE but i am getting the warning at server startup.
I agree. Here's the link:
