The first assignment is to program a CORBA application. It is described here.
The jar for the Client program can be found here.
To be able to connect to the common Server there is an ior-file here. If the server for some reason must be restarted, you must use the new ior-file that will be put here after each restart. (This will hopefully not be necessary).
The idl file for the assignment can be found here.
