2.5.5.2 File System Analogy

The CascadingServiceMBean provided in the Java DMK 5.1 makes it possible to mount MBeans from a source MBean server under a target domain path in a target MBean server, in a similar way to a File System mount operation.

Although our API also allows you to implement different cascading schemes, we recommend that applications only implement those schemes that can be compared to a regular File System mount, as follows.

• When calling the CascadingServiceMBean.mount operation, always use a non null targetPath. The target path can be assimilated to a target mount point in the File System analogy.

• Never use a targetPath under which MBeans are already registered in the target MBean server. Using such a target path could cause a naming conflict when mounting the source MBeans to the target MBean server.

• Never give the same targetPath to two different mount operations. Like in the file system analogy, you should not attempt to mount two sources to the same target path.

Our implementation does not enforce those rules, but applications which are concerned with naming consistency and coherency should make sure to respect them. See the package description in the API documentation for the com.sun.jdmk.remote.cascading package for details.
