Goal

• In this exercise you’ll get more experienced with distributed programming using CORBA.

Part 2: the Chat Client/Server program

Goal

• Create Servant classes for the chat client/server application provided here.

You are given

• Java files MyChatApp.java, chat.idl and ChatServer.java.

You are required

• To make the chat application work by creating necessary servant classes.
• DO NOT MAKE CHANGES TO THE MyChatApplet.java file. Your code will be tested using the original file.

Instructions

• View the final documentation for the chat client here. Especially look at the documentation of MyChatApp and ChatClientServant.
• View the final documentation for the chat server here. Especially look at the documentation of ChatRegistryServant.
• Compile the IDL interface in the chat.idl file.
• You are required to implement the ChatRegistryServant and ChatClientServant classes as specified in the documentation.

• Compile the server program with the created servant class.
• Compile the client program with the created servant class.
• Start the name service, the server program and some clients to test your code.

Note: You’ll have to put all your java files in directory named ChatApp and also name your IDL module ChatApp as the package for your code.

Submission

• Pack your entire application in a zip file with a readme file containing instructions of how to run the server and client programs.
• Send your zip file and class file to mailto://com3240-grader@ccs.neu.edu with COM3240-EX611 as the subject.
