The making of ChessJam Flex/AIR + ColdFusion + LiveCycle DS = fun project!

A few weeks ago, I unveiled a weekend project that I’ve been involved in for several months called ChessJam.  I am now making good on my promise to share why we the selected the technologies behind this desktop application for playing online head-to-head chess. Obviously this is primarily a personal project but there is a […]

New ChessJam blog created for game-specific posts

I’ve created a separate blog for ChessJam-specific news.  I will continue to blog about ChessJam here on Greg’s Ramblings but only when it’s relevant to the Adobe developer community.  For example, I’m working on a new post that goes into some details on how the app was built with Flex, AIR, ColdFusion and LiveCycle Data […]

ChessJam and Robots – A.I. saves the day

My pet project – ChessJam – live online chess with a fun attitude

For the past eight months, I’ve been working with two friends, Todd Williams and Sean Carey, on a little side project called ChessJam.  This project started in February, 2009 when Sean and I decided to play a game of online chess with each other to finally resolve who was the better player.  We explored several […]

MAX Lab: Making Real-Time Data Come Alive with Flex Data Visualization

If you are attending Adobe MAX, I’d like to invite you to come to what I think will be a fun BYOL (bring your own laptop) lab that I am co-presenting with Holly Schinsky.
I’ve always been fascinated with data visualization, especially data that needs analysis as it is generated.  For example, financial transaction data can […]

Using a MySQL Datasource with Tomcat and LCDS 3.0

I’ve spent today becoming familiar with LiveCycle Data Services 3.0 and am excited by the direction the product is going in. You’re going to hear a lot more about model driven development from us and I think LCDS 3.0 is a product that 1) makes full use of the Flash Platform and Flex’s capabilities and 2) shows what it takes to build a genuine rich Internet application.

One issue I ran into though was getting a MySQL database to work with the Tomcat installation of LCDS 3.0 so I wanted to quickly blog the steps I went through. The instructions here were hugely helpful and I wanted to break them down for an LCDS-specific install of Tomcat

  • First you need to get the MySQL drivers for Java which are available here. As of this post the most recent drivers are version 5.1.
  • Copy the mysql-connector-java-5.1.8-bin.jar file into the lib/ directory of your tomcat install (/Applications/lcds/tomcat/ by default).

Once that’s copied, open the xml file for your specific server inside of the tomcat/conf/Catalina/localhost/ directory. In this case, I’m using the default lcds server, so I need to change lcds.xml. You’ll also see the other servers that come with LCDS 3.0 like lcds-samples.xml and ds-console.xml.

Copy this code into that file anywhere inside the Context tags and replace {databaseName} with the name of your database, and change the other {} variables accordingly.

    <Resource name="jdbc/{databaseName}" type="javax.sql.DataSource"
          username="{username}" password="{password}" />

Now you’re all set! Once you’ve got RDS set up on your LCDS 3.0 server you’ll be able to see the MySQL database and start using it for your model driven development.
