http://sourceforge.net/projects/tcljava/ is the home for this software. There is an active mailing list at this site for questions and support issues. TclBlend is a Tcl extension which, with appropriate setup and auxilarly tools, allows one to call Java classes from Tcl. Requirements include a recent version of Tcl compiled with threads and a recent version of Java. Note that TclBlend is an extension which requires a number of environment variables to be set. That is why the TclBlend community recommends using a script that comes with the extension which is designed to set all the various variables before invoking tcl. http://softwaredev.earthweb.com/sdopen/sdososj/article/0,,12421_630531,00.html is an article by [CL] on TclBlend and Jacl. ---- See also [Jacl] - [Java and Tcl] - [Tcl and other languages], and [CL]'s personal notes on TclBlend [http://starbase.neosoft.com/~claird/comp.lang.java/tclblend.html].
