Look at chapter 6.3 of the JGroups manual at http://www.jgroups.org/javagroupsnew/docs/manual/html/user-advanced.html#.... You'll need to create 2 MuxChannels, 1 per service that wants to share the channel. Also, there are unit tests in the JGroups src distro that show you how to use the Multiplexer, or take a look at ChannelMultiplexer.java for a demo. You could also look into the JBoss source code (JBoss 5, CVS head): ClusterPartition.java: protected void createService() throws Exception { log.debug("Creating Multiplexer Channel for partition " + getPartitionName() + " using stack " + getMultiplexerStack()); channel = (JChannel) getMultiplexer().createMultiplexerChannel(getMultiplexerStack(), getPartitionName()); if(use_debugger && debugger == null) { debugger=new Debugger(channel); debugger.start(); } channel.setOpt(Channel.AUTO_RECONNECT, new Boolean(true)); channel.setOpt(Channel.AUTO_GETSTATE, new Boolean(true)); log.debug("Creating HAPartition"); partition = createPartition(); // JBAS-2769 Init partition in create log.debug("Initializing ClusterPartition: " + partition); partition.init(); log.debug("ClusterPartition initialized"); } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3985796#...
