I made that change, but still get the error.  I did notice that I'm getting
warnings as well.  From one of them I saw that that the 'user' paramenter in
server.xml needed to be 'username'.  I fixed that and am now down to the
original error and warnings as seen below.  (I saw in a posted message from
last year that you indicated that with those kind of warnings there was a
database connection problem.)  What I was wondering, since I have looked at
the source for TorqueInstance.java, is whether the torque.database.default
property is used by getConnection when you are using JNDI pooling.  I ask
because the test database name is 'inventory_test', but the production
database name (my default in torque.properties) is 'inventory'.  Is that
going to be a problem?

WARN  org.apache.torque.oid.IDBroker - IDBroker is being used with db

use transactions to limit the possibility of duplicate key generation. 
Without transactions, duplicate key generation is possible if multiple JVMs
are used or other means are used to write to the database.
