Re: [orca-list] orca, java access bridge and java

[Willie Walker <William Walker Sun COM>]

Hi Michael:

If you have Java CORBA internals, ORBit internals, and potentially 
PyORBit internals knowledge, we could use your expertise in tracking 
down the intermittent failures we are running into.

For the keyboard problem, we still have your bug logged as 
http://bugzilla.gnome.org/show_bug.cgi?id=525650, which also points to
http://bugzilla.gnome.org/show_bug.cgi?id=318615.  I believe the main 
problem is that Java has its own idea of keycodes which differs from the 
keycodes used by the X Windows System.  So, funky keycode translation is 
needed.

The funky keycode translation is currently being done in 
src/orca/scripts/toolkits/J2SE-access-bridge.py:consumesKeyboardEvent. 
It basically takes the keysym of the event and passes it to X asking for 
the keycode.  This is not a very good solution.  I believe the real 
translation should be done in the Java Access Bridge and not in Orca.  I 
did something like this for a Java-based VNC client I wrote several 
years back and need to dig up the code and propose a patch for the 
bridge.  It's basically a huge ugly table.

However, in my mind, the intermittent failure we're getting is far worse 
of a problem and I'm spending my efforts trying to get some traction 
with that problem.
