experience with jack, a yacc-like tool for java

A few days ago I posted to this group asking whether there was a
yacc-like tool that created java code.


Several folks mentioned that I should try 'Jack', at
  http://www.suntest.com/Jack/index.html
while others suggested I try CUP, at
  http://www.cc.gatech.edu/gvu/people/Faculty/hudson/java_cup/home.html


I'm writing this note to let other folks know of the existence of
these programs.


As to my personal experience with them, I have not had the chance to
try CUP yet. I decided to try Jack first, since, coming from Sun
Microsystems, I figured it might be more stable than CUP.
Unfortunately, I couldn't get Jack to work on my machine, on the
examples in the 'examples' directory. For anyone who is interested, I
paste below my signature line a script of what I tried. Maybe my java
is installed wrongly -- this is a bit of a dead issue because our
system managers are too busy to fiddle with it. I wish good luck to
others who try this.
