That it compiles shows that RCXPort.class is there,
it should be in c:\lejos\lib\pcrcxcomm.jar (you can check with
jar tvf c:\lejos\lib\pcrcxcomm.jar
).
So apparently the java command doesn't get the proper classpath
You can try giving it explicitly on the command line:
java -classpath ...
Hope this helps
