If you have an jar file with the required classes (local/remote and home interface of your beans), you can put it in the WEB-INF/lib/ directory of your .war file.
Otherwise you can put the classes in the WEB-INF/lib/classes directory.

Hope this helps.

you will need to make your ejb class files visible to your web side.
To do this you should have a MANIFEST.MF in your war file with something like

Manifest-Version: 1.0
Class-Path: ./lib/my-ejb-client.jar


(Make sure to put a few blank enter lines after the class path line too)
