Hey, how are these tutorials doing, i can’t seem to find number 5, and am enthralled.

This has been a fantastic set of tutorials so far.

I’m just picking up these technologies and your style is perfect for the typical development approach I use. Explaining the “whys” as well as the “whats”.

I just hope you keep going and that the SAS framework changes don’t cause too much of a detour.

I already have Spring security included in my list for this tutorial — we used it on a couple projects with Flex and I ported it over to a small PoC that I’ll reuse for this tutorial series. Unfortunately, though, I won’t get into Spring security until several parts later when I actuall start digging into Spring for Java. That said, I will be adding a login form with role based permissions to part 5 that will set us up for Spring security. It’ll basically allow 2 different types of users: Admins and Basic Users. The Admin will be able to add & remove employees.

As for the HTTP session and Cairngorm…the Flex client (and Cairngorm for that matter) don’t really manage or have anything to do with the session…the browser does. The Flash Player (”FP”) leverages the browser’s HTTP connections, so it’s not really directly connected or responsible for managingtracking the session…the browser is. However, on the BlazeDS (”BDS”) and/or LCDS side, you can access the session with the following Java API: FlexContext.getFlexSession();

The assets directory…we’ve had many internal and external discussions on where to put this bad boy…there are issues with Flex Builder not always grabbing your “assets” and copying them to the output folder, so we’ve changed the structure a bit to get around the issue. Part 5 is a complete revamp of SAS + CG (again since they released the full docs for Spring AS on SpringActionScript.org) and I’ll have it out shortly…then I’ll get back to the addition of BlazeDS with Remote Objects.

When I release the code for Part 5, I’ll probably suggest users pull the code directly or start a new, combined Flex + Java project.

Addition of Spring security will be very useful. Brian, could you also discuss about how Cairgorm handles HTTP sessions (is there a Session tracking API much like in Servlets?). I believe most people will be looking for the code that goes in the Service Locator which eithes makes a JNDI call or uses DI to access Spring managed beans.

I really appreciate this series and the work you are putting into it. I am a beginner at this and step-by-step is just what I need. Based on that, I noticed two extremely minor things that tripped me up for a bit:

1: At the end under Build and Run the Application you wrote:

“If you expand your Java project, you’ll see a WebContent directory and a new flex directory that was generated for us when we built our Flex project. Copy the assets directory from the root of our Flex project into WebContent.”
- A prior figure shows your directory structure assets in the WebContent/flex/assets folder. That is where I put them (as shown in the figure) and it works. When I put assets under WebContent alone, it doesn’t load. Of course, you did point out in the sentence before the newly created flex directory under WebContent.

2. Also, when I copied project 3 into 4, I forgot to rename EmployeeManagementConsole3 to 4.

It is no small task to explain this material to someone as new at this as I am, and you are doing a great job.

By the way, I would be happy to Beta test Part 5 at the risk of you concluding that certain individuals like me should not be allowed to download open source software.

Thanks again.

I’m going to release part 5 shortly, although it’s taking a slight deviation from what I had planned originally…

The Spring AS (”SAS”) framework has been changing quite a bit and they’ve released new docs for both the framework itself and the Cairngorm (”CG”) extensions, so I’d like to revisit my SAS + CG implementation leveraging their approach.

I’ve also added in a login screen to set up the use of Spring security on the Java side — it also allows me to illustrate the use of multiple Cairngorm Events + Command + Delegate paths with both hardcoded AS and XML Delegates.

The actual code is done, now I just have to write about it…hoping by EOW. Thanks for following along.

Very good implementation of design patterns. Truly impressed!!
When is part 5 coming out?
