In application scenarios like this (and particularly because you seem to
have multiple systems on the go) the thing that you need to consider is
You need to consider what happens if there's a failure at any stage in the
process, the aim being to ensure that there's no way you can:
i) charge the customer when it looks like you haven't
ii) charge them but fail to keep a record of it
iii) not charge them but make it look like you have...
iv) etc.
Across multiple systems this can be difficult!  (Particularly if there are
flat-files involved - it's a lot easier to do if you're only using
(transactional) databases.)
Of course it's not actually necessary to work-around all the potential
problems if the business are prepared to take the risk....

Apologies if you knew all that already!

Subject: RE: Apache-Tomcat mod_jk

Well I took the novice route and started all over again.  I got Tomcat
4.1.12  itself back up and running, but without mod_jk installed.  I haven't
had a chance to get back to trying again today, but I will tomorrow.  If I
run into the same problems, I will post my entire server.xml file, and
hopefully all you nice people will find something that my untrained eyes

Maybe a little background on my project will help determine exactly what it
is that I need.  I have a site running on Apache 1.3.27 (mostly HTML, some
XML) on RedHat 7.3.  This site, through a connector, is pulling information
from a UNIX system.  That part works fine.  I get to the last screen, where
the connection to UNIX is broken, but not before I am passed a transaction
number.  I then direct the user to an HTML form, where I collect all their
credit card information.  This is the point I am at now.  What I need to do
from here is collect the info and transmit it to the payment processor
through an API call, which I will either use servlet or JSP.  Then I will
display an updated page that varies depending on what the response is from
the payment processor.  All this over a secure connection of course (which
from what I understand will be another battle).  I then have to send the
info I receive back to the UNIX system to be updated.  (If anyone has any
experience in a similar situation or any input regarding this project it is
definitely welcome).

Hope the background paints a clearer picture...  Will post tomorrow when I
try to set up mod_jk again.
