JExpress version 7.8.9 has been
released (11/3/2011). This lets you create Java-based multilingual
installers and auto-updaters. An easy to use Swing interface lets you
design your installers quickly without requiring any programming. It
can also select the exact classes your Java app uses, build your
directory tree, and produce JAR files.
