How to open SWJava on WinXP?

[Mark or Mary Esther Penner]

Question:
I want to use SWJava on my XP.When I click on
SignWriter5.0 or signwriter.jar, as per directions in the
pdf manual, I am asked what program I want to use to open
this file.

What do I answer?
Do all WinXPs come with Java 1.4.1, or is this something I
need to purchase to make SWJava work on my XP?
