Question

I’ve been trying to execute the commands to run the RMI Hello world example but I Failed!

My execution steps are taken from here: http://docs.oracle.com/javase/1.5.0/docs/guide/rmi/hello/hello-world.html

The commands are:

• javac: works fine and I get the class files
• rmiregistry &: I get something like [1] 17122
• java -Djava.rmi.server.codebase=file:/users/ha/RMI/ example.hello.Server:

Gives me an error message

Exception in thread “main” java.lang.NoClassDefFoundError:
example/hello/Server Caused by: java.lang.ClassNotFoundException:

Answer 1

I did solve this problem by running each command on a new terminal window.
First I started with javac for the .java files, then run the command rmiregistry &.

Second I opened a new terminal window and run the command java for the Server class.

Third I opened a new terminal window and run the command java for the Client class.

and it works with me!
