[tcljava-user] Running JACL on Windows XP from Windows command line.

[Patrick F. <pfi...@oz...>]

I have set up a jacl installation on Windows XP to run from the windows 
command line.  Mysys is not needed at runtime but it's still needed for 
the compile stage(generation of jacl.jar and tcljava.jar).  I just 
converted the jaclsh script from bash to dos.  See below.

I installed following the instructions at this link 
"http://wiki.tcl.tk/9993" but set up my directory structure a little 
differently.

I created "D:\JACL" then copied the Sun 1.3.1 JDK directory into 
"D:\JACL\jdk1.3.1_01".  I set the install directory options to "d:\jacl" 
and the jdk location to "D:\JACL\jdk1.3.1_01" at the mysys make/install 
stage and finally I copied the demo directory from the jacl download 
directory to "D:\JACL\demos".  The final install directory structure 
looks like:

D:\JACL\bin
D:\JACL\demos
D:\JACL\jdk1.3.1_01
D:\JACL\lib

The advantage of this approach is that it packages the 1.3.1 JDK with 
JACL so that it's possible to zip up the directory structure and port 
the installation from machine to machine(Windows) with no need to 
re-compile.  JACLSH.cmd starts the jacl shell.  Just make sure the bat 
file directory locations are correct i.e. "c:" or "d:".
