  server.java

  Server for simple client/server CORBA application with file-based IORs.

  To run this example, prepare your environment as follows:

c:\ set ORB=c:\JOB-4.1.0\lib
c:\ set PATH=c:\orbacus\bin
c:\ set CLASSPATH=.;Hallo;%ORB%\OB.jar
c:\ jidl --package Hallo Hallo.idl
c:\ javac Hallo\*.java
c:\ java Hallo.server
