Thread: Java access bridge with Orca
Java access bridge with Orca
user name
 2006-05-09 11:36:08 
    Hello,

I am having problems running Java jfc/swing applications
under Gnome.
The output Orca is providing consists of randomly looking
characters.
The following software components are used:

Debian testing, Gnome 2.14, orca 2.3, jdk 1.5.0 Java access
bridge for gnome 1.5.0.

The access bridge has been installed as follows:
1. Compiling of sources.
2. make install
the resulting files (gnome-access-bridge.jar, JNav.jar
accessibility.properties) are installed in to the directory
/usr/local/share/jar/. I've created symlinks from the
gnome-access-bridge.jar and JNav.jar  to
$JAVA_HOME/jre/lib/ext and
from accessibility.property to $JAVA_HOME/jre/lib

With symlinks created, JRE seems to be able to load the
access bridge.

Thanks in advance for your suggestions!


Vladyslav

Hello Vladyslav,

I looks like the Java Access Bridge is installed correctly. 
What Java 
applications are you testing with?  Also, what output are
you 
describing?  Is it debug output or output in the Braille
monitor?

Thanks,
Lynn

I've been testing access bridge with the sample
applications
distributed with the Sun JDK package. especially with the
Java
implementation of Notepad found in
$JAVA_HOME/demo/jfc/Notepad.

I am describing the speech synthesizer output. If invoked,
Notepad.jar
starts throwing an exception stack trace. I'm attaching it
at the end
of the message.

The characters I've mentioned are just console output of
java VM
preceding the exceptions stack trace:

I see similar problems trying to run Notepad against the
version of Orca in
CVS HEAD. I've just filed bug #341423 on this. See:

  http
://bugzilla.gnome.org/show_bug.cgi?id=341423

for more details. Thanks for reporting this.
