SWT is the approved GUI framework for E-on-Java. (AWT is also supported, but there is concern about the correctness of its taming due to its complexity).

SWT on Mac OS X

For proper GUI behavior, it is generally necessary to execute SWT applications on Mac OS X from within a Mac OS X application bundle. There is a utility, macify-swt.e, to do this provided in the scripts directory of the E-on-Java distribution.

Snow Leopard compatibility

OK, it seems that we've found a combination that works:

1. Use the 32 bit version of Java (can be set using the "Java
Preferences" utility).

2. Download the correct version of SWT: "Mac OSX (Mac/Carbon)". If you
are getting lot of "just leaking" messages, you downloaded the wrong
one. We used this version:
