It may be installed as is, or used as a starting point for building a MBean which includes JE support. <p> JE management is divided between the JEApplicationMBean class and JEMBeanHelper class. JEApplicationMBean contains an instance of JEMBeanHelper, which knows about JE attributes, operations and notifications. JEApplicationMBean itself has the responsibility of configuring, opening and closing the JE environment along with any other resources used by the application, and maintains a com.sleepycat.je.Environment handle. <p> The approach taken for accessing the environment is an application specific choice. Some of the salient considerations are: <ul> <li>Applications may open one or many Environment objects per process against a given environment.</li> <li>All Environment handles reference the same underlying JE environment implementation object.</li> <li> The first Environment object instantiated in the process does the real work of configuring and opening the environment. Follow-on instantiations of Environment merely increment a reference count. Likewise, Environment.close() only does real work when it's called by the last Environment object in the process. </li> </ul> <p> Another MBean approach for environment access can be seen in com.sleepycat.je.jmx.JEMonitor. That MBean does not take responsibility for opening and closing environments, and can only operate against already-open environments. <p>This bean was copied from bdb je 2.0 source and modified so could pass in and monitor an environment created externally. Also added toString versions of the locks and stats calls since the objects don't seem to make it over the RMI divide (Not serializable.
