Cant get socket example to work

[harmmeijer]

I am new to java so this might be a simple mistake I am making but I cannot seem to make an example work.

http://java.sun.com/docs/books/tutorial/networking/sockets/clientServer.html

compiled the KnockKnockProtocol.java
put the KnockKnockProtocol.class in the classpath.
tried to compile the KnockKnockServer.java but get an error:

C:\j2sdk1.4.0_03\bin>javac code\KnockKnockServer.java
code\KnockKnockServer.java:28: cannot resolve symbol
symbol : class KnockKnockProtocol
location: class KnockKnockServer
KnockKnockProtocol kkp = new KnockKnockProtocol();
^
code\KnockKnockServer.java:28: cannot resolve symbol

KnockKnockProtocol kkp = new KnockKnockProtocol();

2 errors

The example does tell you how to run the program but there is nothing to run because the code won't compile.
