Re: [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 ?
