Hi Bob,
I'm not using Torque with Struts (using Turbine) but I have seen the
following before:
> WARN - IDBroker is being used with db 'biztracker', 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

What solved it for me was that I put the Torque.jar file in the
webapplication's lib directory, ie
$TOMCAT_HOME/webapps/<appname>/WEB-INF/lib/Torque.jar
When I did this, the above warning disappeared.
In addition I also noticed the following problem when using Tomcat
v4.1.12 (please keep in mind I'm using Turbine and postgresql, so this
might not apply to you):

-----------------------------------------------------
When I "downgraded" back to Tomcat v4.0.6, the above problem
disappeared. I don't have time to debug the Torque JAR or commons-dbcp
JAR file to figure out the problem, but will follow this up when I have
a bit more time.
Hope this helps.
cheers,
