After you've built some SQL in the tool, you have the option of either copying the SQL you build to the clipboard-to paste into your CFML template-or "saving" the query for later use. The option to copy to the clipboard is easily missed. It's represented by two icons listed at the top of the query builder (they're the last and next to last from the right). The first icon copies just the SQL, while the second copies the SQL with a CFQUERY wrapped around it. After clicking one of those buttons, the SQL is copied to the clipboard and you can paste it into your code (after closing the query builder window) using the Edit>Paste command, or CTRL-V.

Making the Move to J2EE

Welcome to the first installment of Journeyman J2EE. I'm honored to present this new bi-monthly column of ruminations and reactions as I, like so many of you, make my foray through the vast world of J2EE application development and deployment. But this isn't intended just for newbie J2EE developers. On the contrary, I hope to also share tips and techniques of value to experienced JSP/servlet developers. The definition of a journeyman is "a competent and reliable performer or exponent." To me, it connotes a day-to-day working craftsman. Does this describe you? Are you like a journ... (more)

Exploring Amazon Web Services with ColdFusion MX

Amazon.com, the "earth's biggest selection," has exposed their entire catalog of products, product reviews and ratings, user-created book lists, and more via Web services. Whether you're new to Web services or not, and even if you don't care so much about accessing Amazon's data, it presents an interesting case study of doing Web services in CFMX. You might even be able to turn the opportunity into profit! In this month's Journeyman column, I'll walk you through using Amazon Web Services (AWS), and along the way will point out some of the key points you need to know about CF (an... (more)

Using JSP Custom Tags in CFMX

CFMX, the new release of ColdFusion, will allow us to use JSP custom tags within our ColdFusion programs. Some may say, "So what?" In this article I hope to show you why it's definitely worth looking into this new possibility. At the time of this writing CFMX, previously known as Neo, is still in beta and the nondisclosure agreement prevents people writing about its features, but one of the few things that have been public knowledge since last year's DevCon is the ability to leverage JSP custom tags. I've been given the OK by Macromedia (indeed the encouragement) to show this st... (more)

New Possibility in CFMX: Server-Side Redirects

Now that we can talk freely about ColdFusion MX, I want to share something new that you likely won't hear much about... ...but that I think stands to be an important feature: server-side redirects, or "forwards." It's something CF has long been missing, and an improvement over CFLOCATION. The thing about a forward is that it's quite different from, and in most ways much better than, a CFLOCATION. We've all used CFLOCATION to transfer control from one CF page to another. But did you know that it performs a client-side redirection? The user doesn't see it happen, and maybe you nev... (more)
