31 /**
32  * A server program that can set up an arbitrary CORBA servant.
33  * The program takes the name of the servant class to use from
34  * the command line. It then creates an instance of this class,
35  * using its no-arg constructor (which must exist). It registers
36  * the instance with the POA, and prints the resulting IOR to
37  * standard output. If anything goes wrong, a message starting
38  * with the string "ERROR" is instead written to standard output.
39  * <p>
40  * This program is intended to be used with a
41  * {@link ClientServerSetup ClientServerSetup}. To read and process
42  * the <code>TestServer</code>'s output from another program such as
43  * the above, JacORB's normal diagnostic messages should be completely
44  * silenced. This must be done using the normal configuration settings,
45  * e.g. from the command line (see
46  * {@link ClientServerSetup#setUp ClientServerSetup.setUp()} for an
47  * example).
