Hi Paul I am a newbie in EJB...so don't know if this will really helps.. I guess u implement the finder methods in the bean class? and also modify the Home interface file to add that method in.

RE: EJB finder methods.
For Container Managed Persistence beans, you just add the method to the Home
interface:
public Collection findByField1 ( String field1 ) throws FinderException ,
RemoteException ;
The container will automatically write the finder method for you.
For Bean Managed Persistence beans, you put the same method in the Home
interface,
but you must write your own finder method in the EJB class:
public Collection ejbFindByField1( String field1 ) {
... SQL statements to find Collection
return Collection.
}

RE: EJB finder methods.
First of all implement the Entity Bean with Container Managed Persistence. In that case you'll need to have finder method declared in Home interface and implemented in Primary Key class. YOU WILL NOT HAVE finder METHOD IN EJB CLASS for CMP. It will be written by the container at the deployment time!

RE: EJB finder methods.
In a finder method, how do you automatically have a custom SQL statement...For instance: CREATE TABLE names ( nameID int, fname char(20), lname char(20), city char(40)) Collection findByCity(String sCity); I would like to set an ORDER BY lname in my finder method...I know it can be done in the application deployment, but what about if I ship my EJB to other companies, do I have to have them edit all the application deployment .xml files to add custom finders?

RE: EJB finder methods.
Yes, Unfortunately at the moment there is no way to port finders in orion-ejb-jar.xml from server to server. You can include this file in the .jar though and Orion will deploy it with your finders intact. (Other servers will just ignore it as far as I know) Mike -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Jeremy Cowgar Sent: Tuesday, 29 August 2000 11:56 To: Orion-Interest Subject: RE: EJB finder methods.
