Torque Tutorial Problem

[Tim Clotworthy <tc...@bka-inc.com>]

Hello,
I am having a little problem getting the torque tutorial to run. I am
running the tutorial using Oracle 9i for the database on my laptop. When
trying to run the application, I get the following error:

C:\java\jakarta\torque-3.0>java com.kazmier.Bookstore
java.lang.NullPointerException: Connection object was null. This could
be due to a misconfiguration
of the DataSourceFactory. Check the logs and Torque.properties to better
determine the cause.

org.apache.torque.util.Transaction.safeRollback(Transaction.java:221)
        at com.kazmier.om.BasePublisher.save(BasePublisher.java:426)
        at com.kazmier.om.BasePublisher.save(BasePublisher.java:401)
        at com.kazmier.Bookstore.main(Bookstore.java:26)
C:\java\jakarta\torque-3.0>lsnrctl startup

And the torque log specifies the following corresponding information:

WARN - IDBroker is being used with db 'bookstore', which does not
support transactions. IDBroker attempts to 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.

I am assuming that there is something wrong with my configuration that
might be causing this, but I'm not sure what to look for. Can anyone
give me any pointers?


Thanks in advance.

Please disregard this, as I figured out the problem was due to the fact
that I was using an existing Oracle database instance that was not named
"bookstore", and had not completely changed all the parameters
appropriately.
