I:\ip\jputre\java\osdi\keyboard\key1\src>java -version
java version "1.2.2"
Classic VM (build JDK-1.2.2-004, native threads, symcjit)

I:\ip\jputre\java\osdi\keyboard\key1\src>

On Windows NT, and win2000, non-standard keys generate a keyevent (keypress,
type, reelase) with a Keycode=0. Our application has ~ 160 keys. The KeyCodes
are seen by Windows, also seen by MS's VM (jview), but the SUN JVM sets the
KeyCode to 0 and there is no way for our app to act on the keys.

The problem is similar to BugId 4290799 (and others) in that the new Windows
start  & applications keys (keycode 91,92,93) generate KeyEvent KeyCode=0. The
new  internet keyboards (pro) with browser keys behave the same way.

I suspect there are many other keyboards (point of sale, etc) that could utilize
additional keycodes, most of which are application-specific & therefor the
KeyCodes are not needed by JVM.

If the jvm does not recognize the keycode, I believe it should leave it as-is,
so an application can then recognize it & act. At a minimum it seems there
should be a properties or mapping or init file that defines the valid keys, but
I haven;t found it.

Sample program below, click in the typing area, press the MS windows or
application key, the keycode is allways 0. other keys work fine. Try with an
internet keyboard if you like, and with MS's jview.

Here's the System.Out info from the keypress:
KeyCode=0 modifiers=0
KeyEvent=java.awt.event.KeyEvent[KEY_PRESSED,keyCode=0,keyChar='?'] on textfield
0

If there's a workaround or something i've missed, i'd appreciate any help.

thanks in advance.

FULL PRODUCT VERSION :
java version "1.4.0_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0_01-b03)
Java HotSpot(TM) Client VM (build 1.4.0_01-b03, mixed mode)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195]
SP 2

A DESCRIPTION OF THE PROBLEM :
When using newer Internet-enabled keyboards such as the
Mircosoft Internet Pro, or Compaq EasyAccess keyboard,
the internet / extended keys such VK_BROWSER_BACK, _FORWARD,
etc through VK_LAUNCH_APP2 (WIndows VKs, not java Keyevent)
all return keyCode 0 for KeyPressed events getKeyCode()

They should return valid keycodes.

Similar to Bug Id 4352104, but not quite the same.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.connect Microsoft Internet keyboard.
2.run KeyEventDemo
http://java.sun.com/docs/books/tutorial/uiswing/events/KeyEv
entDemo.html
3. press any of the internet keys.

EXPECTED VERSUS ACTUAL BEHAVIOR :
expected: valid keyCodes
actual: key code = 0

ERROR MESSAGES/STACK TRACES THAT OCCUR :
KEY PRESSED:
    key character = '?'
    key code = 0 (Unknown keyCode: 0x0)
    modifiers = 0 (no modifiers)

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER WORKAROUND :
Use Microsoft Java.
