Subject Re: Question about a sample Application

#1. The example asks you to create a DB named InventoryDB and then run
some sql commands to create tables.

#2. Your web.xml has a resource ref to jdbc/InventoryDS. This is a
part of the jndi name of the datasource (not database).

#3. The geronimo-web.xml links your jdbc/InventoryDS with the
datasource's name called InventoryPool.

#4. Then the InventoryPool.xml which is the alt-DD for the RA links
the InventoryPool datasource with the InventoryDB you created in #1.

This is the usage link for the InventoryPool under "Database Pools"
navigational link. If you have deployed the Inventory app, you will
see this link too.

Hope this helps
