Are you a CF Server administrator? Or a developer with an interest in knowing
how your server is configured and managed? Are you aware of all that should
be done to keep the server running well - or all that could be done to make
the most of it?
One View of CF Administration
In this two-part article we'll look at some of the things CF administrators
should be paying attention to, as well as some of the things they should take
advantage of but may not have noticed. We'll discuss aspects of managing the
server that extend beyond the CF Administrator interface, including tasks for
keeping the server environment healthy and running effectively.
What this will not be is a boring review of each page in the CF
Administrator, nor will we get bogged down in trivialities like how to create
a data source. The Macromedia ColdFusion manuals (and online help in the
Many developers know that the CF administrator can restrict your ability to
use several tags that not only provide very useful capabilities, but can also
be used to provide unauthorized access to server resources. What many don't
know is that they can arrange to use those restricted tags on a case-by-case
basis with the administrator's permission.
In this article, I introduce the Unsecured Tags Directory feature, which most
developers don't know about and many administrators don't understand. This
feature can be the key to unlocking tags that might otherwise render a
There are many facets to J2EE Web application development. It's a powerful
platform that offers a variety of possibilities and capabilities, with many
different approaches and models of development available. This is both a
strength and, for newcomers to the platform, an Achilles' heel.
In this installment of Journeyman J2EE, we look at the many sides of J2EE
development with a focus on the diversity, dichotomy, and divided opinions
that can challenge even experienced developers, but especially newcomers.
Consider these some warning signs on the road to J2EE.

While many experienced CF developers will spurn the notion of creating a
production CF application with a back-end database in Access, there are far
more developers who for one reason or another proceed to - or simply have to
- do so.
If you've got to deal with Access, you may as well deal with it in the most
effective manner possible. This article introduces a significant new feature
for Access developers that will bring dramatic improvements in query
processing performance as well as modularization of code. In the bargain,
you'll find it significantly eases upsizing from Acces... (more)
Have you ever wished CFINPUT provided a way to validate an e-mail address? Or
were you frustrated that its telephone validation didn't allow parentheses
around an area code among other such limitations?
Well, your wish has been granted in a new, little-known feature of CF5.
While many will know of the top 10 or so new features in CF5, few will know
about the dozens (yes, dozens) of less-promoted enhancements. One of these is
the ability to validate user input by way of regular expressions. (If you're
new to regular expressions, we'll show you some examples and point you to the
