[infinispan-dev] How to add programmatic config to an exisitng xml configured cache

Hi, I have some infinispan configurations available in "config.xml". After loading this configuration, I want to append some more configurations programmatically, using Configuration Builder. I am doing something like this : Configuration template = null; ConfigurationBuilder builder = new ConfigurationBuilder(); DefaultCacheManager manager = new DefaultCacheManager( "config.xml"); template = manager.getCacheConfiguration("evictionCache"); builder.read(template); builder.loaders().passivation(false).shared(false).preload(true) .addFileCacheStore().fetchPersistentState(true) .purgerThreads(3).purgeSynchronously(true) .ignoreModifications(false).purgeOnStartup(false) .location("tmp").async() .enabled(true).flushLockTimeout(15000).threadPoolSize(5) .singletonStore().enabled(true).pushStateWhenCoordinator(true) .pushStateTimeout(20000); manager.defineConfiguration("abcd", builder.build()); The problem with this code is, it's overwriting the evictionCache configuration. Can somebody help me to fix this issue? Thanks, Faseela
