As a proof of concept, I try to build an infinispan cluster with an existing application which starts an embedded cache and one or more standalone infinispan servers.
The reasosing behind this is, that I want to show, that there is a way of zero-configuration automatic creation of a cluster by simply starting freshly downloaded infinispan standalone servers. So my application runs an embedded cache which will be automatically "joined" by new nodes.
I'm using the very default configuration for infinispan and jgroups (see below).
The effect is, that two or more of my applications with embedded cache "see each other" and two or more standalone infinispan servers see each other. But none of my nodes "see" the standalone nodes and they don't see my nodes.
I use infinispan 6.0.2.
The standalone server is this: http://downloads.jboss.org/infinispan/6.0.2.Final/infinispan-server-6.0.2.Final-bin.zip
Please give hints on what to check or links to ressources I could study to make this work.
This is the code, that starts the embedded cache:
DefaultCacheManager manager = new DefaultCacheManager(
GlobalConfigurationBuilder.defaultClusteredBuilder().transport()
.nodeName( node ).addProperty( "configurationFile", "jgroups.xml" )
.build(), new ConfigurationBuilder().clustering()
.cacheMode( CacheMode.DIST_SYNC ).build() );
Cache<String, String> cache = manager.getCache( "default" );
This is the jgroups-config I'm using:
