This post details the steps I took to install Red5 from source on a CentOS 5.5 base server. 1. Install Java using yum. (The -y flag provides a ‘yes’ answer to all prompts.) 2. Install the Apache ant binary. I downloaded the most recent release one directly from Apache’s archives. The version installed using yum […]

Starting with certain versions in the 9.0’s of Flash player, socket communication in Flex began adding additional security measures. The one I am going to discuss in the post is the socket policy file. In short, the socket policy file is an XML file that is served by default from port 843 and contains information […]

Client-server programming is one of my passions, and I enjoy doing it in almost any language. Which makes it fitting that Flex (ActionScript) is one of my favorite languages to develop in, because it truly is a client-side technology which pretty much means it’s open to just about any type of backend server. I suppose […]

One of my ongoing weekend projects is an AIR chat application, recently rechristened “JUICE” a.k.a. “John’s Ultimate Internet Chat Experience”. I realize that may only be the case for myself, but the project has been very educational and entertaining for me. The initial release used AIR/Flex as the front-end, ColdFusion and MySQL for the backend, […]

This is part two of a two part series. See part one, Messaging with Flex/ColdFusion via BlazeDS : Part 1 (CF configuration) This installment will go over setting up messaging in Flex, and assumes everything is working correctly on the server. Recall I will be covering two scenarios. A client-publish/client-subscribe model, and a server-publish/client-subscribe model. […]

I just went through setting up Flex / ColdFusion messaging via BlazeDS, and have come through it rather unscarred considering it’s my first time using Flex messaging. Most of the documentation I have regarding messaging is biased toward Java (including the sample apps included with BlazeDS). A lot of what I found online, though very […]

I started this post a few months ago while I was working on an AIR application that uploads files to a remote server (by way of an upload script).  I ran into this error, Error #2044: Unhandled IOErrorEvent; text=Error #2038: File I/O Error,  which caused me considerable grief until I discovered the simple solution.  I got […]

I stumbled upon this post by Allen of Dobeweb.com, where he gives detailed instructions for setting up an EC2 image complete with BlazeDS.  He gets down into the nitty-gritty of running EC2 from the command line (which I haven’t done in a long time… I use the Elasticfox plugin for keypair and instance management) and […]

I may be doing an internship this summer, at which I will begin developing back-end support for my Flex applicatiopns using Cold Fusion.  I may be posting on that in the future, depending on how it goes.  I just wanted to document two resources I will be using along this process. The first is The Smith […]

I use Maven as my primary build & deploy utility for the Flex/Java development that I do. It may be a configuration error on my part that I’ll eventually need to look into, but every time I build my project, Maven builds the entire thing. This is especially annoying in two circumstances… first, when the […]
