Compiling and running the Hello World Application

Compiling the Client Application

1. Compile HelloClient.java:

   
   javac HelloClient.java HelloApp\*.java 
   

2. Correct any errors in your file and recompile if necessary.
3. You should see HelloClient.class in the project directory.

Compiling the Server

1. Compile HelloServer.java:

    
   
   javac HelloServer.java HelloApp\*.java
   

2. Correct any errors in your file and recompile if necessary.
3. You should see HelloServer.class and HelloServant.class .

Running the Client-Server Application

1. From an MS-DOS system prompt (Windows) or command shell (UNIX), start the Java IDL name server:

   tnameserv -ORBInitialPort nameserverport 
   

2. From a second prompt or shell, start the Hello server:

   
   
   java HelloServer -ORBInitialHost nameserverhost
        -ORBInitialPort nameserverport
   

3. From a third prompt or shell, run the Hello application client:

    
   
   java HelloClient -ORBInitialHost nameserverhost 
        -ORBInitialPort nameserverport
   

4. The client prints the string from the server to the command line:

   Hello world!!

Remember to stop both the tnameserv and the HelloServer processes after the client application returns successfully.
