This message is to announce the new 1.2.2 release of Jacl and
Tcl Blend. These releases are the result of a joint effort by
Christopher Hylands, Mo DeJong, and Bryan Surles. The goal of
this project is to extend and improve the 1.0 release of Jacl
and Tcl Blend which was originally started by the Sun Tcl team.
The 1.2.2 Developers release of Jacl and Tcl Blend are available for
downloading at the following URL:
http://www.cs.umn.edu/~dejong/tcl/tcljava
The 1.2 release is a developers release and should be considered alpha
quality. Version 1.2.2 includes lots of bug fixes and some new features
that make it even easier to use Tcl and Java together. Jacl users will
be interested in a workaround for a Windows JDK 1.2 bug which stopped
characters from being echoed to the command line until return is pressed.
Both Jacl and Tcl Blend users will be interested in the new ability
to pass Java long objects to java methods. In addition, a new
java::autolock command has been added which can halt garbage
collection during interactive sessions.
What is Jacl?
----------------
Jacl is a 100% Java implementation of Tcl 8.0. This allows Tcl to run
in more environments and also brings the power of scripting to Java
developers. Jacl only implements a subset of the Tcl language (the C
version of Tcl has a lot of features!). However, the core of the
language is implemented and well tested.
What is Tcl Blend?
------------------------
Tcl Blend is a Tcl Extension that allows you to have access to the
Java VM from the Tcl interpreter. The goal here is to allow Tcl
developers to write new Tcl extensions in Java rather then C or C++
for better portability. Currently, Tcl Blend is only known to work
with Solaris and Windows 95/NT. However, it should be easy to port
Tcl Blend to any system that supports dynamic loading and the Java JNI
interface.

Christopher Hylands maintains his own page that lists a plethora of
information. There are links to related Web pages, his own personal
notes about building and using Jacl and Tcl Blend, and in depth
explanations about Tcl and Java integration. This information can be

Scriptics support for Jacl and Tcl Blend:
-------------------------------------------------
It is important to understand that this release is due entirely to the
efforts of Christopher Hylands and Mo DeJong. Scriptics currently has
a minor, facilitating role in Jacl and Tcl Blend and is not officially
supporting these releases.
If you have a problem with Jacl or Tcl Blend or you think you have
a great idea for a feature, you should send an email to the tcljava
mailing list. Please do not send email directly to the authors.
