Object-Oriented JNI for .NET (low-level) - Object-Oriented JNI for .NET (low-level), Library for .NET Framework v.1.1. Supports Standard JNI interface (SUN/IBM/MS JDK1.1.x-1.6.x) for developing and running code in C#, MCpp, VB, J#.

The main features available:

- JNI code can be written only in managed code;

- supported .NET languages: C#, VB, J#, Managed C++;

- implements regular JNI SDK compatible with JDK1.3.x (32 bits) and above;

- supports two ways of Java Native methods implementation: from Java code with System.loadLibrary(...) or System.load(...) and from JNI code with RegisterNatives(...)/UnregisterNatives(...);

- Java native methods are implemented only with .NET managed functions;

- marshaling and unmarshaling of .NET data types are hidden from Developer;

- implemented special mechanism for shellow copy of Java references in JNI code to reduce a number of them in JVM, save JVM Heap and improve JNI code performance.

Comment:

- to implement Java native methods from Java code with System.load() or System.loadLibrary() you should load OOJNI.NET20.DLL first in some place of your Java code. Set path to OOJNI.NET20.DLL and your .NET module like to any C++ JNI library;

- this update includes fast cast operations from/to Java primitive arrays to/from .NET primitive arrays.

The same library for .NET Framework v.2.0 is available at

Gets the 4-byte 32-bit binary volume serial number of a Windows
disk drive assigned when it is formatted to provide and almost unique id.
Dont confuse this with the volser(, the string name,
or the manufacturers disk serial number assigned to a hard drive at the factory.
Uses JNI and C++ native code.
Consists of java and JNI you include in your own code.
You can test with
C:
CD \com.mindprod.volser
java.exe com.mindprod.volser.Volser
and ensuring nativevolser.dll is on the path, e.g. in the
current directory. YOU MUST MANUALLY EXTRACT
NATIVEVOLSER.DLL and put it on the path. See
http://mindprod.com/jgloss/path.html
To use getVolser, you need three pieces of code in your
class:
1. an import,
2. a static init to load the JNI library
3. a call to the getVolser native method
i.e.
import com.mindprod.volser.Volser;
...
static
{
// get DLL loaded from somewhere on java.library path.
System.loadLibrary( "nativevolser" );
// if have troubles change this code to use
// System.load( "E:\\com\\mindprod\\volser\\nativevolser.dll" );
/**
* test harness
*
* @param args not used
*/
public static void main( String[] args )
{
// Needs drive letter with colon and trailing backslash
final int volser = Volser.getVolser( "C:\\" );
System.out.println( "4-byte Volume serial number for drive C: is " + Integer.toHexString( volser ) );
}
}
Volser does nothing much by itself, other than a debugging
test harness to demonstrate getVolser method.

In Java, allows you to find out where the mouse in on the
screen, even when it is not over one of your apps. This has
similar function to MouseInfo.getPointerInfo in Java 1.5+.
This class will work in any version of Java.
It uses JNI and a DLL, so it only works on Windows.
You must install the nativemouse.dll somewhere on the path.
Then your programs can find out the x and y position of the
mouse, [(0,0 is the upper left of the screen] at any time by
calling:
Point p = com.mindprod.mouse.Mouse.getWhereMouseIsOnScreen()
Java and C source included.
You can test the program by typing:
java -cp C:\ com.mindprod.mouse.Mouse
Where C:\ in where you installed the com/mindprod/mouse
directory.
The nativemouse.dll must be on the path, e.g. in the current
directory. With JDK 1.5, the DLL can be in the jar, so long
as it has no package path.
