Volser - Gets the 4-byte 32-bit binary volume serial number in Windows.

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.Don`t confuse this with the volser(, the String name, or the manufacturer`s 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.Volserand ensuring nativevolser.dll is on the path, e.g. in thecurrent directory. YOU MUST MANUALLY Extract NATIVEVOLSER.DLL and put it on the path. See http://mindprod.com/jgloss/path.htmlTo use getVolser, you need three pieces of code in your class:1. an import,2. a Static init to load the JNI library3. a call to the getVolser native methodi.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 debuggingtest harness to demonstrate getVolser method.
