My advice would be to: 1. Check out JBoss Cache from SVN and get it to build. 2. Take a look at TxInterceptor.java line 1243 or so. Try to get it to work. 3. You can configure the unit test suite to use your TX manager, see if you can't get it to work with Atomikos. 4. Unfortunately I don't see a way to configure the TxInterceptor. Create a JIRA issue and explain you want to configure this behavior. Actually, it seems like you can mark a method as @Inject and JBoss Cache will inject a configuration object. Not sure if there's any XML that pertains to the TX interceptor. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4129314#...
