I have a client/server program that attempts to send and receive an object.

There are three packages: server, client and shared shared contains only the Message class

I put Message.java from shared package into the same folder as calcclient package source files and calcserver package source files.

I compile using the line: javac -classpath .; Message.java They can compile. Then I change directory up one level and ran with: java -classpath .; .Main

When I use Netbeans to run, the entire program works as per normal. But not if I run from command line. If its executed through command line, the program will work until it needs to use the Message object. Then it will show a NoClassDefFoundError

Am I putting the right files at the right places? How do I get the program to find shared package through command line?
