The com.ice.jni.registry package implements a Java native interface to the Windows Registry API. This package allows you to access, modify, and export registry resources. The package includes all source code required to build the native interface, as well as the DLL required to implement the native code.
Please read the license before tomorrow.
The Registry class provides a main() class method that provides a simple test program to test the native interface. It is what I used to test the code. When you run the test program, you can type the command "help", which will print the commands that you can use.
