Using the Java ATK Wrapper with Orca

[Paul Hunt]

Hi list,

I've just started a programming course in Java and we're getting onto
building UI's with swing.

I am using Ubuntu 9.04 (Jaunty) and the latest version of Orca (2.28)
for accessibility.

I know that either the Java access bridge or the Java ATK wrapper is
required for screen reader accessibility so I have installed the ATK
wrapper (as the access bridge is being deprecated).

I installed it from its git repo but when I try to run a simple
demonstration program (one that runs without the ATK wrapper, albeit
inaccessibly) I get the following error output;

Exception in thread "main" java.lang.UnsatisfiedLinkError: no
atk-wrapper in java.library.path
     at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1709)
     at java.lang.Runtime.loadLibrary0(Runtime.java:823)

     at FlowButtons1.<init>(FlowButtons1.java:13)
     at FlowButtons1.main(FlowButtons1.java:48)

Can anyone help?

Thanks.
Paul

Hi Paul,

It seems that Java cannot find the libatk-wrapper.so.
How did you configure Java ATK Wrapper? Was the so file installed into
the path where Java can find?

Regards,

Ke
