org.apache.geronimo.kernel.config.ConfigurationManager
Encapsulates logic for dealing with configurations. Configurations have a lifecycle with three states: installed, loaded, and running. Installed means that the configuration is present in the server's repository. Loaded means that the Configuration GBean (including the configuration's ClassLoader) is running. Running means that all the GBeans in the Configuration are running. From a user perspective, there's not much difference between installed and loaded if the configuration has not been started (it still shows up as not running). However, certain operations will cause a configuration to be loaded but not started. For example, if ModuleA depends on ModuleB, then when ModuleA is distributed ModuleB will normally be loaded (to fire up the ClassLoader and validate ModuleA). But ModuleB will not be started at that point. It can be started manually or it will be started automatically when ModuleA is started. When a Configuration is not loaded, only its ConfigurationData is available for inspection. It's normally not possible to inspect the GBeans in the configuration because there's no ClassLoader that could be used to load the classes needed by the GBeanDatas in the configuration. Once the configuration has been loaded, it's ClassLoader is available so the GBeanDatas can be loaded and inspected. But the GBean instances are not instantiated and started until the configuration is started. @version $Rev: 601152 $ $Date: 2007-12-04 18:49:03 -0500 (Tue, 04 Dec 2007) $
