[jboss-jira] [JBoss JIRA] Commented: (JBCACHE-1392) Use the correct MBeanServer if multiple MBeanServers are present.

Use the correct MBeanServer if multiple MBeanServers are present. ----------------------------------------------------------------- Key: JBCACHE-1392 URL: https://jira.jboss.org/jira/browse/JBCACHE-1392 Project: JBoss Cache Issue Type: Bug Security Level: Public(Everyone can see) Components: JMX Reporter: Robert Buck Assignee: Manik Surtani The prior bug did not fix the issue of running the cache under jboss when the following options are present: set JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote The code is presently as follows (which is incorrect, by the way): {code} 157 List servers=MBeanServerFactory.findMBeanServer(null); 158 if(servers == null || servers.size() == 0) 159 throw new Exception("TreeCacheView.init(): no MBeanServers found"); {code} TreeCacheView fails to deploy because it is using the wrong MBeanServer. Rather than doing the above, you should either do something like: {code} import org.jboss.mx.util.MBeanServerLocator; ... // find the local MBeanServer MBeanServer server = MBeanServerLocator.locateJBoss(); {code} , or you should do something like this: {code} public static MBeanServer getDefaultMBeanServer() { return findMBeanServer("jboss"); } private static MBeanServer findMBeanServer(String agentId) { List servers = MBeanServerFactory.findMBeanServer(null); if (servers != null && servers.size() > 0) { for (Object object : servers) { MBeanServer server = (MBeanServer) object; if (server.getDefaultDomain().equals(agentId)) { return server; } } } return null; } {code} The reason is because with Java 5, when the "-Dcom.sun.management.jmxremote" switch is turned on, the default platform MBeanServer is the zeroth instance rather than "jboss". See: http://fisheye.jboss.com/browse/JBossCache/core/support-branches/1.4.1.SP... To test, deploy the tree cache view, and start JBoss with the JAVA_OPTS mentioned above.
