The documentation for AS5 has been revamped :) Its available at http://www.jboss.org/ejb3/docs/ | | The specific chapter for EJB3 entity caching is here http://www.jboss.org/file-access/default/members/jbossejb3/freezone/docs/... | | P.S: I haven't heard about ejb3-entity-cache-service.xml in earlier versions too. Okay, I have gotten around to deploying my application using the documentation above, but I get the following exception: Caused by: java.lang.IllegalArgumentException: unknown config mvcc-entity It appears to not see the configuration in server/all/deploy/cluster/jboss-cache-manager.sar/META-INF/jboss-cache-manager-jboss-beans.xml. Is there another step in the configuration to make this work? Do I have to put something in the file jboss-cache-configs.xml? Thanks.
