First, compile the server program with a JDK 1.1.x compiler, e.g.:

setenv CLASSPATH /users/dcl0bjc/public_html/Java
javac CountServer.java

This javac command will compile CountIF.java, CountServant.java and CountServer.java to produce the files CountIF.class, CountServant.class and CountServer.class.

At a Unix/MS-DOS prompt, run RMI's rmic command on the file CountServant.class:

rmic RMI.Count.CountServant

This command will create the files: CountServant_Stub.class and CountServant_Skel.class. These files contain the bytecodes of the stub and skeleton.

Now compile the client program:

javac CountClient.java

Before running the server, we need to start the RMI-Registry. We can do this using RMI's rmiregistry command. On Unix, type:

rmiregistry &

whereas on Windows 95/NT, type:

start rmiregistry

The server can then be started using a command like:

java -Djava.rmi.server.codebase=http://hercules.dur.ac.uk/~dcl0bjc/Java/ \
   RMI.Count.CountServer &

This should output:

CountServant: constructor called

Finally, run the client program:

setenv CLASSPATH /users/dcl0bjc/public_html/Java
java RMI.Count.CountClient hercules.dur.ac.uk

The client program continually reads in lines from the keyboard. If the line contains the string quit, the client program is terminated; if it contains show, the client program displays the current value of the remote object; otherwise, the client program expects the line to contain an integral value and it instructs the server to set the remote object to this value.
