Just an update on what I am doing regarding JBCACHE-840. The best approach seems to be to create UnitTestCacheFactory with following signatures: Cache createCache(Configuration c); Configuration createConfiguration(int type); //type=sync|async Cache createCache(int type); //type=sync|async UnitTestCacheFactory will have inner parser class that that is a subclass of XmlConfigurationParser. This subclass will read cache configuration file which will have all supported jgroups stacks. Something similar to mux stacks. When invoking create methods of UnitTestCacheFactory jvm parameter will be consulted to decide whether to crate udp, tcp, tcp-nio stack and so on. If you have some suggestions shoot back. _______________________________________________ jbosscache-dev mailing list jbosscache-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/jbosscache-dev
