Calling Java - and back

> Hello world,
>
> It's now possible to call Java from VisualWorks - and to call back!
>
> Here's a screenshot showing a workspace with code which opens a Swing
> window, the Swing window showing the Smalltalk class hierarchy using
> callbacks, and VisualWorks logging the Java VM's debugging output in the
> Transcript. (The Swing example is taken from Chris Uppal's JNIPort
> documentation.)
>
> The latest version of JNIPort for VisualWorks which enables callbacks is
> in the Cincom Public Repository. This may a bit premature because there
> are still exceptions and JVM crashes with certain combinations of
> options (involving lazy ghost classes and the VFPrintfHook), but I
> couldn't resist. :-)
