Note addition of wonka-0.9.4.
Thanks to Johnny Lam for checking the package before I commited it.
This package is made with the 'xsim' AWT device and the OSwald scheduler.
A pthreads (o4p) based scheduler is being worked on.
What is Wonka?
Wonka is ACUNIA's cleanroom Virtual Machine for the JavaTM language. It
is extremely portable and self-contained, and can optionally be used with
its own real-time executive (OSwaldTM) to provide a complete solution for
embedded devices. It is a full implementation of the Java language, not
just a subset. And it's Open Source.
An Embedded VM
We didn't build a Virtual Machine first, and then look for a market; we
had a project, we had some hardware, and the project required that
hardware to run Java. The result is a Java implementation designed from
the start for embedded systems.
A VM for Real-Time
That system has real-time requirements; maybe not Hard Real-Time, but
hard enough for most of us. We don't claim to have made a totally pred-
ictable Java (it may not even be possible), but we have worked hard to
bring Java's inherent unpredictability under control.
A Java2-compatible VM
Some embedded VMs sacrifice full Java compatibility for other aims. Wonka
doesn't. Automatic garbage collection, dynamic class loading, user-
defined class loaders, fine-grained access control, they're all there.
The standard distribution doesn't include JavaBeansTM or Swing, but you
could add them if you wanted to: all the infrastructure needed is present.
Full AWT 1.1.8 Support
Wonka comes with a high-performance lightweight AWT (RudolphTM) suitable
for any memory-mapped or framebuffer display. Or you can plug in your own
implementation, or run with no AWT at all (e.g. in a ``headless'' system).
The choice is yours.
Free and Open Source
The Wonka Public License was conceived with the needs of embedded system
developers in mind. You don't have to make your entire business open-
source in order to use Wonka, nor do we insist you join a ``community
process''. The WPL is based on the well-known BSD license (revised
version), which is accepted by the community as being a genuine Open
Source license and as a free software license, compatible with the GPL.
