Tom,
I may be a bit late on this. My advice to you would be to upgrade your JFW
version. You're trying to do something with a version of JFW that is four
years old, now.
I believe that starting with JFW version 4.01, there was support for Adobe
5.05 which has the accessibillity plug-in. The current version of JFW 5.0812
has support for Adobe Acrobat 6.
