<DD>Gets the names of MBeans controlled by the MBean server. This
 method enables any of the following to be obtained: The names
 of all MBeans, the names of a set of MBeans specified by
 pattern matching on the <CODE>ObjectName</CODE> and/or a Query
 expression, a specific MBean name (equivalent to testing
 whether an MBean is registered). When the object name is null
 or no domain and key properties are specified, all objects are
 selected (and filtered if a query is specified). It returns the
 set of ObjectNames for the MBeans selected.
<P>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>name</CODE> - The object name pattern identifying the MBean names
 to be retrieved. If null oror no domain and key properties are
 specified, the name of all registered MBeans will be retrieved.<DD><CODE>query</CODE> - The query expression to be applied for selecting
 MBeans. If null no query expression will be applied for
 selecting MBeans.
<DT><B>Returns:</B><DD>A set containing the ObjectNames for the MBeans
 selected.  If no MBean satisfies the query, an empty list is
 returned.
<DT><B>Throws:</B>
