javah Help - "No classes were specified on the command line"

I'm running Ubuntu Linux with Eclipse installed, and I'm trying to work with JNI to do so I need to use javah, but it doesn't seem to be working I have just recently installed Ubuntu and am unfamiliar with Linux/bash shells

for my eclipse project called myJNI, I have class DoJNI containing the native method.

in Terminal:

javah -classpath .;\home\thomas\Documents\LinuxProgramming\EclipseWorkspace\myJNI\bin\org\me\jni DoJNI

errors I get are: No classes were specified on the command line

Use forward slashes instead of backslashes, and a colon instead of a semi-colon:

javah -classpath .:/home/thomas/Documents/LinuxProgramming/EclipseWorkspace/myJNI/bin/org/me/jni DoJNI

Also, I suspect that you don't really want org/me/jni on the classpath, but just the bin directory, using the classname org.me.jni.DoJNI:

javah -classpath .:/home/thomas/Documents/LinuxProgramming/EclipseWorkspace/myJNI/bin org.me.jni.DoJNI
