[antlr-interest] Running ANTLRWorks 1.3.1 -- javac error

[Karljurgen Feuerherm]

Hello,
 
I'm new to this product (and to modern products of this type
generally... was a B programmer in the early 80s and trying to get
updated!)
 
I'm on Windows XP, and have run the JAR file to invoke ANTLRWorks.
 
I'm trying out the Expression Evaluator Tutorial. Interpreter works
fine, but invoking the debugger gets me
 
"java.IO.IOException: Cannot run program "javac": CreateProcess
error=2, the system cannot find the file specified"
 
(Oddly, after a while, trying it again got me a different error about
timeout, even though I'd changed nothing [Sure. Famous Last Words,
eh?].)
 
Not sure where to go from here... By all means be pedantic in a
response :)
 
Thanks!
