OJB-0.9.9 + MySQL ODMG Startup Problem
Greetings,
I'm trying to do my first OJB project, and I'm not getting very far. I
was able to get tutorial1 to work, and I was able to use the Persistence
Broker functionality in my own test app just fine by basically copying
tutorial1 code into a test app and modifying it a bit. So PB API works
good.
Now I'm trying to use the tutorial2, ODMG API, and I get the same error
trying to run the tutorial2 program as I do when I copy its code into my
test application. I have heard no changes need to be made to the
repository.xml files to switch API's, correct me if I'm wrong.
As I said, the PB API works fine for me, but using the same xml files
and when I try to db.open(databaseName, Database.OPEN_READ_WRITE) I get
the following stack trace:
===============================

<connection-pool
maxActive="10"
whenExhaustedAction="1"
validationQuery="SELECT COUNT(*) FROM user"
/>
</jdbc-connection-descriptor>
===================================================================
I haven't changed any of the other configs.
Any help at ALL would be very much appreciated.
