Re: [orca-list] question about Orca and something called Processing

[Michael Whapples <mwhapples aim com>]

Having a quick look at processing I notice a few things which may impact 
on accessibility, and may explain what you observe.

Processing is a java application, I guess probably using swing for the 
GUI, so requiring the java access bridge or java atk wrapper (I will 
continue only saying java access bridge but this includes the java atk 
wrapper unless I state specifically otherwise). Now possibly a bit 
annoyingly it seems the linux file you download bundles a JVM with it 
and if the start up script finds its local JVM then that will be used. 
This causes an accessibility issue as the bundled JVM has no java access 
bridge installed in it. Either you could install a java access bridge to 
the local JVM, or from how I read the script delete the java 
subdirectory from processing and it will fall back to using the system 
default JVM.

If you do opt for getting it to fall back to the system JVM then 
remember you will need the java access bridge installed and working for 
orca to speak anything in this application. You may want to check your 
system JVM with other java applications to ensure the java access bridge 
is properly functioning if you have problems.

I hope that helps.
