I'm having a lot of trouble getting the default Drools persistence stuff working as it's documented in the Drools Flow manual. Below I've included the stack trace, my dependencies (only those related to drools persistence), my code snipped (which gets compiled into a jar and used by a war) and the persistence.xml file (which is also compiled into the jar under META-INF/persistence.xml). Any help would be appreciated. *Note: I tried posting this yesterday, but it doesnt seem to have made it to the mailing list, so sorry for a double post if it did * Stack trace: 2010-01-07

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 ?
