27     Represents a manageable J2EE servlet. Servlet will expose some manageable
28     attributes defined by its descriptor and they will be made available.
29     For every Servlet that is loaded by a running Server Instance, there will
30     be a correponding MBean registered in the MBeanServer. Note that the life
31     cycle of Servlet is not manageable by this interface, because it is
32     not exposed by its descriptor.
33     <p>
34     The Servlet can be running as a part of deployed application or an
35     independently deployed module. In case the servlet is loaded from an
36     independently deployed module, the application name (in the ObjectName)
37     is treated as default application name or null.
38     <p>
39     Object Name of this MBean is:
40         ias:type=J2EEServlet, AppName=<appName>, ModuleName=<modName>,
41         ServletName=<servletName>
