but when i run the program i get the following
error...
/****************************************************************************/
[EMAIL PROTECTED] lib]$ javac HelloJNIWorld.java
[EMAIL PROTECTED] lib]$ java HelloJNIWorld
Exception in thread "main"

public native void displayHelloWorld();
static {
System.loadLibrary("libHelloIMP");
}
public static void main(String[] args) {
new HelloJNIWorld().displayHelloWorld();
}
