When launching a Java application with these options: -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=0 -Dcom.sun.management.jmxremote.local.only=false Java uses an ephemeral port, which is very useful to avoid collisions. Is it possible to get the actual port (or connection URL) programmatically from within the application ? String url = sun.management.ConnectorAddressLink.importRemoteFrom(0) .get("sun.management.JMXConnectorServer.0.remoteAddress"); System.out.println(url); This will

I am running a client/server application using JBoss. How can I connect to the server JVM's MBeanServer? I want to use the MemoryMX MBean to track the memory consumption. I can connect to the JBoss MBeanServer using JNDI lookup but the java.lang.MemoryMX MBean is not registered with the JBoss MBeanServer. EDIT: The requirement is for programmatic access to the memory usage from the client. Unlike the JBoss server's MBeanServer, the JVM's MBean server doesn't allow remote monitoring by default. You need to set various system properties to allow that: http://java.sun.com/javase/6/docs/technotes

I spent some time checking out JBoss AS7 today. I am impressed with what I have seen so far but I noticed that good ol' JMX-Console no longer exist. Does anyone know why it was left out? I understand that I can connect through JConsole, MC4J etc. but is there an alternative that would provide web based access to the deployed MBeans? According to this thread (see below), there will be no such thing. Server management will be achieved in another way - via JBoss native interfaces. There will be, however, a compatibility layer exposing JBoss services through JMX. http://community.jboss.org/thread
