[rules-users] Drools Persistence Problem

I'm using Tomcat 5.5.27 -- I followed the guide you posted, so everything
described step by step is how I set up my Tomcat instance.
The only difference was, when I used the JNDI config they have in
resources.properties, and added the <Resource> tag in context.xml, I get an
error that says:
Caused by: javax.naming.NameNotFoundException: Name jdbc is not bound in
this Context
However, when I remove the <Resource> from the context.xml and remove
everything from resource.properties, and put back the code I posted
originally (the snippet where I created a new PoolingDataSource and
registered it via InitialContext), I get the error I posted about the file
locking.
I hope that provides some ideas. Is there something that maybe I described
wrong in persistence.xml -- should I try using comp/env/jdbc/testDS1 instead
of jdbc/testDS1 ?
Thanks.
