Weird keyboard error in Java IDE's


Hi,

When using NetBeans, Jedit or any other IDE written in Java, i'm unable to produce the vertical bar (|) character. This makes java programming a bit difficult of course

My keyboard layout is Danish, wich makes the "bar" an Alt-Gr combo, but other Alt-Gr combos works fine. The problem persists with both blackdown and sun java (1.4.1 and 1.4.2-04), and I've also tried different locale settings without any luck.

What really puzzles me is, that when I'm using a non-danish locale (POSIX), the special danish characters will produce a square in the IDE editor (wich is understandable - i can fix this changing my LANG var to da_DK), but the vertical bar simply produces no response at all!

Perhaps it's worth mentioning that the font used in the editors, displays the vert. bar perfectly in non-java x-applications.

I sure hope some of you guys can help me out here. Thanks.

Best regards,
LTJ

Well, I've done some further research now, and we're apparently dealing with a known problem with java and so called "dead keys". Since I'm no expert on how Linux deals with keyboards/keymaps, I have no idea what to do with this piece of information.

Also I've tried out a little test app from netbeans.org, wich outputs info on key events. The output fom pressing Alt-Gr + Vert. bar is:

Code:
java.awt.event.KeyEvent[KEY_PRESSED,keyCode=65406,keyText=Alt Graph,keyChar=Undefined keyChar,modifiers=Alt Graph,extModifiers=Alt Graph,keyLocation=KEY_LOCATION_STANDARD] <snip>
--------------------------------------------------------------------------------
java.awt.event.KeyEvent[KEY_PRESSED,keyCode=129,keyText=Dead Acute,keyChar=Undefined keyChar,keyLocation=KEY_LOCATION_STANDARD] <snip>
--------------------------------------------------------------------------------
java.awt.event.KeyEvent[KEY_RELEASED,keyCode=129,keyText=Dead Acute,keyChar=Undefined keyChar,keyLocation=KEY_LOCATION_STANDARD] <snip> 
--------------------------------------------------------------------------------
java.awt.event.KeyEvent[KEY_RELEASED,keyCode=65406,keyText=Alt Graph,keyChar=Undefined keyChar,modifiers=Alt Graph,extModifiers=Alt Graph,keyLocation=KEY_LOCATI ON_STANDARD] <snip>
--------------------------------------------------------------------------------
Unfortunately this setup (NetBeans + Sun JDK) works perfectly in Win32.
C'mon, we can't let them win this one!?
