/**
* A server program that can set up an arbitrary CORBA servant.
* The program takes the name of the servant class to use from
* the command line. It then creates an instance of this class,
* using its no-arg constructor (which must exist). It registers
* the instance with the POA, and prints the resulting IOR to
* standard output. If anything goes wrong, a message starting
* with the string "ERROR" is instead written to standard output.
* <p>
* This program is intended to be used with a
* {@link ClientServerSetup ClientServerSetup}. To read and process
* the <code>TestServer</code>'s output from another program such as
* the above, JacORB's normal diagnostic messages should be completely
* silenced. This must be done using the normal configuration settings,
* e.g. from the command line (see
* {@link ClientServerSetup#setUp ClientServerSetup.setUp()} for an
* example).
