Hello Roger,

Yes I see your situation ... when non techies are confronted by
choosing between XYZ technology and one has a cost and another
apparently has no cost ... they classically drift towards the zero
cost solution. I sometimes wonder how much 'impl' detail to give to
people making cost decisions ... e.g. there is always a cost
associated with adopting any software.

I believe what your challenge is to present the true costs of both
approaches; remember to include major risks as well (what if Oracle
wanted to try and kill off Java ???). as the positives (xslt has a
rich history in document manipulation)(extensible markup is not going
away). Software is a bit different then buying some part of a piece of
machinery, it can enable cost optimisations but it can also present
new opportunities which create new revenue generating scenarios ... I
sometimes think the most successful software is when it was brought in
to do a job (does it well), and also enables a range of future
positive scenarios.

While having a 'free' implementation may seem like a 'silver bullet'
solution to your conundrum its not ... you have enough 'free' out
there IMO to tell your non techies the story.

A software license of a few k to a medium sized company represents a
very minor cost (Compared to the humans running/managing the software)
.. .its easy to demonstrate how the license pays for itself, getting
over that first unit of currency is the issue.

gl, Jim Fuller

capability in Java and distribute it for free to the people in the field."

are people with real, operational needs. Particular technologies is of no

purchase licenses costing many yy thousands of dollars -- that gets their
attention. And immediate dismissal of XSLT/XPath.
