When I started this project back in March, I could not get anything to work with JDK
1.1.8, Tcl
8.3, and TclBlend 1.2.5, so I used Tcl 8.2.3. I do not remember now what the symptom
was, just
that it didn't work. (I am using JDK 1.1.8 because of warnings about JDK 1.2 at
http://dev.scriptics.com/software/java/faq.html#Q4.)

Tcl, or TclBlend? I have not compiled Tcl... should I? (I'm using the binary
distribution of Tcl.)
I will see if I can get anywhere with this approach.
