I have package my slides and source codes. Click here if you wish to download it.
Something that i was unable to share with everyone. I have used BlazeDS with Spring and Hibernate. For my Flex client, i have used Flex with Cairngorm.
Have a look at the codes…
Drop me a msg if you have trouble setting the source codes up. You can tweet me @kennethteo.

I am excited to share this piece of news.

The Singapore Flex User Group is organising The Actionscript Conference on 19 October 2008 at the National Library. Expect lots of exciting things at this conference. Peter Elst is one of the invited key speakers.
The Actionscript Conference is a community conference with the focus on Flash Platform. Attendents will see themselves immersed in a day of learning, knowledge exchange, and networking. TAC aims to bring topics on Actionscript 3.0, Flash development, Enterprise Flex, AIR, Integrating of Flash and other Platforms, and building Rich Internet Application to its audience.
The Actionscript Conference is organised by the Singapore Flex Usergroup. We aim to create a conference for the developers, by the developers.
Since this is a non-profit event, as part of the organising committee, i cordially invite you to join us as a sponsor(Sponsorship details). If you wish to offer your knowledge to this conference, it is much appreciated as we try to make this a successful event.

I am observing pretty bad performance when my BlazeDS services are configured with Apache and Tomcat on mod_jk. Not too sure whether it is because i used Cairngorm as my main application framework. Setting requestTimeouts on my remoteObjects didn’t help. It was until i tried hitting my BlazeDS endpoint directly with my browser that i realised it was Apache that had refused/restricted requests to my Tomcat.

Error message from Apache
What i see on the Apache Error log
Tue Jul 22 18:51:59 2008] [error] [client <ip address>] client denied by server configuration: amfsecure, referer: <url to my flex app>
but i do not see any request with the same timestamp on the Tomcat logs.
Performing tuning is the only way to go. However, my sys admin did hardened and tuned the mod_jk connector settings in the server.xml files. Still waiting for him to try to worker.properties file. Sys Administration is not my kind of work. =p
My guess is that unless you are expecting very low traffic, you should not use the mod_jk setup. I hope my sys admin ain’t gonna get hell from me to ask for a public-facing Tomcat. I sent a message onto the BlazeDS jira below to see if there is any advice on my situation.
