"If you're still using HTML, JavaScript, complicated server deployments, and other technologies that don't "just work," try downloading the free Adobe Flex 3 SDK, a trial edition of Adobe Flex Builder 3 Professional, and the free developer edition of Adobe ColdFusion 8 to begin building better web applications with fewer headaches."

This was my first attempt to combine regular expressions with cfhttp. It’s pretty handy once you get the hang to it, and it can be a very powerful combination. Here’s the script I use to scrape the total number of pages indexed in Google.

Back in February I wrote a blog post on SQL Injection that included an example of how a malicious user might inject into a character field even though ColdFusion escapes single quote marks. The attack involved other forms of escaping single quotes - and was effective against MySQL. This week I stumbled upon (more like a train wreck) an attack that is much more sophisticated - and also involves injection into a character field. I am told.....

I like it when people email me cool stuff. Today Jon emailed me about adding his new project SvnTask to my Ant wiki. SvnTask is a super simple solution for using svn from ant. I just want a 100% Java solution that uses the nice svnkit library. Include two simple jar files and go.....

Fair warning though: once you've started using Mylyn, you never want to return to the old ways....

Similar to Nic Tunney’s Top 6 Underused ColdFusion Functions I figured I would post an Eclipse underused shortcuts for CFEclipse users. I think it was during a CFObjective presentation by Dan Wilson, I witnessed the copy down shortcut (ctrl-alt-down).......

I watched Qasim Rasheed's CFUnited presentation on Continuous Integration with SVN, ANT, CFUnit & Selenium. I picked up a fundamental concept, Conditional Execution, and a cool trick. The concept was the if and unless attribute of an ant target. I have read about them but it was great to see them in action. He covered it quick so I had to watch that section a couple times......

Interesting article that discussed the possible next evolution of web apps.

I've put together an application skeleton for Mach-II 1.5 applications. This application skeleton is a nice way to get a Mach-II application up and running quickly. Neil Middleton, Peter Farrell, Matt Williams and Erik Meier each contributed in some way and Neil Middleton was kind enough to create an ANT task to automate the process The code has been contributed to the Mach-II group and should be available on the official site soon

I have revisited adding Yui compressor into my work's ant build script to minify JS and CSS scripts. We achieved about an average 18% compression rate for all our js/css files. Download example and run with it.

A while ago I built and released ColdFusionBloggers.org as a way to demonstrate and learn about new ColdFusion 8 Ajax technologies. Since then I've wanted to come back to the site and rebuild it using Spry or JQuery. Not because I wasn't happy with the CF8 Ajax stuff, but because a) it's fun to totally rebuild your own sites and b) I wanted to learn more about jQuery.

Simple tutorian on CFM encryption

If you use ColdFusion (or another Java-based CFML runtime), you should be using Java. There's a reason that CF uses Java under the hood: Java is incredibly powerful. Yes the interface to Java from the CF level is cumbersome and creating hybrid CF/Java applications pretty much costs you CF's RAD capabilities, but there are some real gems in the Java libraries.

Clustering in particular with ColdFusion and JRun can get fairly complicated pretty fast and I urge all who are going to embark on clustering to plan out how you want to cluster and why. Another key issue is to make sure when we are creating a web application that it designed and engineered from day one with clustering in mind. I have helped so many clients who hit major problems when they start building clusters, largely because the application was too tightly coupled to the environment it is running in. Hard-coded directory paths would be a classic example. In this blog posting I wanted to illustrate an interesting concept, well two in reality, Horizontal Clustering and Vertical Clustering. Let's look at a diagram....

There have been several blog posts recently about class-loading issues apparently linked the use of the Sun-Java 1.6 (6.0) JVM. Mark Mandel has a detailed article on this here. Before seeing this article we had been working on optimizing a ColdSpring-ModelGlue-Reactor application. We blogged our progress in this article. We thought a reality check was a good idea and ran some load tests comparing this same application performance in Java 1.5 and 1.6. Once again we observed better performance in 1.6; here are the results. These results are for a 50 Virtual User (vUser) Test for 1 hour with 8 second think time (delay between clicks) comparing Java 1 5 to 1.6. Firstly Java 1.5 Total Number of Clicks: 13,345 (0 Errors) Average Click Time of all URLs: 5,298 ms

I have added several blog postings here before on the theories of High-Availability (HA) and Clustering. In this series of blog postings I will be attempting to create dedicated postings for the following scenarios. Please keep in mind that there will be alternative ways to do these things and what I am showing here is drawn from my experiences from either creating clusters for clients or working on existing clusters Here are the scenarios I will be posting on... Setting up a two instance cluster from a fresh install of ColdFusion Load testing a two instance cluster on Java 1.6 (6.0) using the Round Robin algorithm Load testing a two instance cluster on Java 1.5 (6.0) using the Round Robin algorithm

Forget Ruby on Rails; in this article I outline why, as a Java developer, you should perhaps be looking to another technology closer to home to leverage your existing in-house skills and infrastructure. We'll briefly touch on some of the features of ColdFusion, the Java-EE-based application server from Adobe, and discuss why ColdFusion is more relevant today for Java developers than it has ever been.............

Ever wanted to get started with BlazeDS? A bug bit me yesterday that forced me to sit at my computer for hours on end until I could achieve two things: setting up Amazon's EC2 Webservice and getting up and running with BlazeDS. I had to do quite a bit of hunting due to my inexperience with a few things, which led me to the conclusion that someone else out there might want to benefit from my Googling and bookmarking.
