If you've ever wanted to do raw JDBC stuff in your ColdFusion applications, you probably know that you can get a javax.sql.DataSource via this code:
createObject("java", "coldfusion.server.ServiceFactory")
.dataSourceService.getDatasource("myDSN")
Unfortunately, this doesn't work on Railo, because the result isn't actually a javax.sql.DataSource, it just looks like one (see RAILO-43). To put that another way, it's duck typed.
Fortunately, [...]

Next Tuesday (May 25th), I will be presenting CFGroovy to the Tulsa CFUG via Connect. Details are at http://www.tulsacfug.org/meetings.cfm, but the important bit is that it's at 12:30 central time, not in the evening. Steve Bryant – who manages the group – graciously extended a general invitation to anyone else who would like to join [...]

If you can identify this pair of shoes, I'll buy you a drink of your choice next time we meet. If you're wearing a pair of them, I'll buy you two.

This morning, in response to my Processing and Galcon post, I received this email:
Hey,
Stumbled across your article about using processing :) Sounds neat!
Anyway, I don't like having to make these requests – but because of how
trademark stuff works I have to request that you change the name of your
project to something that doesn't contain the [...]

I did a little experiment last night using Processing, which is a Java-based visual programming environment that I've repeatedly run into in various different contexts, but had never really done anything with. I've become completely addicted to Galcon Lite on my iPhone, and figured it was a "sample" to build with Processing. Note that I [...]

I'd like to start with a confession. I love SQL (and it's Hibernate counterpart HQL). Its simplicity and elegance is remarkable. Its expressive power is stunning. It is almost universally disliked by developers. Why is that?
The answer, at least to me, is pretty straightforward. Developers spend a lot of their time programming, so that's where [...]

Last Wednesday evening Sean Corfield and I were chatting over beers and he caught me by surprise with a statement he made. We were talking about the ORM functionality in CF9, and he liked how it just worked. You invoke a setter, and it gets to the database with nothing else. I agree in theory, [...]

This afternoon I presented on Polyglot Programming at cf.objective() 2010. Unlike most presentations I give, this one has almost no code, so the slidedeck (as a PDF) is the whole shebang. The in-deck content is admittedly light; really just an outline to follow along as I talked. The short version of the verbal part is:
Using [...]

Unlike my last several posts, this one isn't ORM related. At least not directly. If you're using ORM, you necessarily care about your domain model's integrity, as it's a prerequisite for ORM doing it's job, but it has nothing to do with ORM specifically. The point of a domain model is to be a representation [...]

I do. Because god knows front controllers and persistence layers don't have a one-to-one correspondence. Turns out that through the magic of application switching you can do it, as long as you're careful with your sessions. Not going to go into details right now, but this code works (and does what you'd expect):
<cfapplication name="ormtest1″ />
<cfset [...]
