First of all... configurationManager.load(myURI); //starts the configuration gbean, but not the gbeans in the configuration configurationManager.loadGBeans(myURI); //loads but does not start the gbeans in the configuration will load the configuration whose ID is myURI, and then load but not start the gbeans in the configuration, so you won't get any port conflicts. Starting the configuration (configurationManager.start(myURI) will load and start the gbeans in the configuration: you don't want to do this. Second, does jmx remoting use the jndi naming port? I keep getting confused about which port jmx remoting connects to. thanks david jencks

I thought so... but now I'm 100% sure myself. :) In the wiki it does deployer:geronimo:jmx:rmi:///jndi/rmi://localhost:1099/JMXConnector (which by the way the path is incorrect) but in my eclipse tooling code... the uri I have is deployer:geronimo:jmx:rmi://localhost/jndi/rmi:/JMXConnector So I'm wondering now myself how its connecting to the correct port, or if not specified it just happens to be defaulting to 1099.

loading gbeans
Is there a way to load a loaded configuration's gbeans' without starting the configuration? I'm basically wanting query a gbean's persistent attribute value on a loaded but not started configuration. Looking through the code the configuration's gbeans are loaded only after its containing configuration is started kernel.startGBean(configName); kernel.invoke(configName, loadGBeans, new Object[] {attributeStore}, new String[] {ManageableAttributeStore.class.getName()}); This makes sense, but I'm wondering if there is an alternate way to get the gbeans attribute values on an already deployed and serialized configuration. ???
