[jboss-jira] [JBoss JIRA] Commented: (JBMESSAGING-1247) Remove requirement for JMX to use JGroups

Remove requirement for JMX to use JGroups ----------------------------------------- Key: JBMESSAGING-1247 URL: http://jira.jboss.com/jira/browse/JBMESSAGING-1247 Project: JBoss Messaging Issue Type: Task Affects Versions: 1.4.1.beta1 Reporter: Brian Stansberry Assigned To: Jeff Mesnil Fix For: 1.4.1.beta2 The current JGroups integration uses JMX to get ahold of a Channel: public Channel createControlChannel() throws Exception { return (Channel) server.invoke(this.channelFactory, MUX_OPERATION, new Object[]{controlStack, uniqueID + "-CTRL", Boolean.TRUE, uniqueID}, MUX_SIGNATURE); } The channelFactory member is an ObjectName injected into MessagingPostOfficeService. Better is to expose a property of type org.jgroups.ChannelFactory and inject an instance of that. That's the POJI interface for an object that provides JGroups channels. Background: JGroups intends to remove the legacy org.jgroups.jmx.JChannelFactoryMBean interface that is being invoked in the above code. That code is reflection based, so as long as a service that exposes the MUX_OPERATION signature is registered in JMX, the call will still work. AS 5 will ensure that such a service is registered, without using the org.jgroups.jmx.JChannelFactoryMBean itself. So, the above JMX-based code will work, and this isn't an urgent issue. But, this usage does tie JBM clustering to JMX, rather than allowing simple MC integration or even manual instantiation.
