Using LogBox For Logging In FW/1

I’ve seen talk of FW/1 and LogBox integration come up a few times on the CFML Slack, so I figured I’d run through a way to get that set up in your application and start using it. What Is LogBox? LogBox is a standalone enterprise ColdFusion (CFML) logging library designed to give you flexibility, simplicity, and power when logging or tracing is needed in your applications. Based on Log4j, LogBox offers capabilities to log events and data in your application using various appenders such as writing to a file, database, and email formats. [Read More]

Working With FW/1 & QB

Steps to Integrate Using Subsystems

Today I wanted to go over a library that I think is pretty awesome and echoes capabilities found in many other modern languages: QB. QB is a query builder DSL written by Eric Peterson, who’s been putting out some really cool modular libraries for the CFML community. With QB, you can: Quickly scaffold simple queries Make complex, out-of-order queries possible Abstract away differences between database engines The syntax uses a builder pattern that makes writing queries more readable and easy to understand when glancing through code.

Crash Course In CFML & jsoup

Over the years I’ve made repeatable use of the jsoup library so I figured it’d be nice to put out a little primer on using it with CFML. What Is jsoup? From the official site: jsoup is a Java library for working with real-world HTML. It provides a very convenient API for extracting and manipulating data, using the best of DOM, CSS, and jquery-like methods. jsoup is designed to deal with all varieties of HTML found in the wild; from pristine and validating, to invalid tag-soup; jsoup will create a sensible parse tree.

Leave Your Tags at the Door: Some CFML Tag to Script Documentation

So after 2 weeks or so of churning away in my free time, I’ve gone and written some documentation. Of what you say? Well, I made an attempt to write some bits on converting CFML tag-based code to CFScript. It’s nothing fancy. More of a “example A, example B” kinda layout where one chunk is in tags and the other is in script. Back at the beginning of firing this up, I was doing a handful of refactoring legacy code.

Exposing Private Fields in Jsoup's Whitelist Class with Reflection

In recent days I’ve been trying to knock out some answers to questions on Stack Overflow. I’ve actually been pretty successful in helping some people out, so I’m happy about that. Two of the questions I ended up answering were in regards to using ColdFusion with Jsoup, a Java based Document Parser, and it’s Whitelist class in some strange different ways. By that I mean they wanted to gain access to data that isn’t freely exposed; and in most cases, I feel you really don’t need it to be. [Read More]

Repeating Watermark with ColdFusion & Java

Let’s make some watermarks with Java. This one’s been in the backlog of my mind for a good while now. It’s really a one situation tool, but it was cool as hell to dig into and figure out how to do it. I had to apply a watermark on a pretty large sum of images. ColdFusion makes this fairly easy. In the given scenario though, it wasn’t just a watermark; but a repeating watermark on a 45 degree. [Read More]

Preserving Order With Java's LinkedHashMap Class

The other night I ran into an issue with preserving order of keys and values being added to some ColdFusion structures. As it would be, structures in CFML don’t preserve data in any consistent order. It’s honestly something I’ve known about, but none the less, something that’s never given me hassle. With that faintly in the back of my mind, I did not accept it as such initially as when I wrote my code and ran it in ColdFusion 11, everything appeared in order (probably not the best route of thinking).

Freak FW/1 & DI/1 Bean Not Found Debugging Issue / Solution

So earlier today I was working on the back end for this blog; which runs on FW/1 and DI/1. I ran into an issue that set me back for a hot minute; mostly because the error was quite vague in regards and I also didn’t stress my debugging options as much as I could/should have (initially)! I was making updates to a service object handled by DI/1 for use in a controller and at one point, all of a sudden, the page using the service bombed on me consistently. [Read More]

Railo / Tomcat 8 Error & Solution For (A child container failed during start)

I noticed a few days ago that a new update for Apache Tomcat 8 was released (8.0.15). Today I decided to go ahead and update my server but ran into a minor hiccup when trying to access my websites tied to Railo. Usually, updating Tomcat 8 with one of it’s minors is pretty straight forward. Download the new version, unzip and swap out the JAR files in the “lib” folder and restart Railo/Tomcat. [Read More]

Fixing Slow Railo Startup Running on Tomcat 8

Over the last week++ I have been taking on the role of Server Admin. I by no means consider myself to be one, let alone good at it; but, since I manage my own VPS through Viviotech, it has deeply become a necessity where there comes that time when I need to be that guy. Quite often more than less. My situation… As of late I’ve been battling frequent occurrences where my server gets brought to it’s knees from hits by various bots; among other things. [Read More]
