It's always a big relief to see a client really embrace a CMS and throw resources at it to get the website moving. Glo-Brite is
a client I've been working with for the last year and we launched their
site about six months ago. We stalled for a while but finally got back
on track as Paul dedicated a resource to load all his heavy duty truck parts, uploading images, creating page titles and descriptions from their catalog.
The site is driven by my home grown CMS "Ham" (an anagram of my
initials). It is driven by an xml configuration file and includes
rollback, file and image uploads and allows you to relate one object
class to another. It runs on MySQL and BlueDragon. Image uploads are
resized using the native java AWT image
library.

I'll post a follow up to this to explain how I arrived at this code as
this was my first experiment at leveraging Java objects within my
applications and once you get it, the process is actually really
straightforward.
The site is configured with Google Analytics and we are tracking
the goal that clients are submitting the contact form as the way to
evaluate the performance of the content on the site and ad campaigns
they are going to run. Some areas are still a little rough but the
client was willing to work on a "more content online is better than
none while we wait for final sign off on every piece" basis. There
will be a few more design tweaks, plenty of content updates and the car
and light duty AJAX driven part browser will be the last piece to
launch.
