Using the Java ATK Wrapper with Orca

[Paul Hunt <huntp ukonline co uk>]

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

Can anyone help?

Thanks.
