Welcome Welcome to our blog about all kind of topics that are related to software development. We blog about:
SOA, BPM, EDA, ECM and all the other buzz words. Beware some post might not be so common as you think. We are not scared to go against main stream thoughts.
Technologies like java, maven, springframework, OSGi and front end technologies and frameworks like jQuery, DWR, Flex.
Finally to make this happen we need tools and of course a Mac (well some of us do). So we blog about that as well.

Some time a go I had a chat with Alef Arendsen. We talked about flex and the integration with springframework. As a lot of you know, I wrote a few posts about that topic. We talked about what the springframework could do to make life easier for spring developers when using flex and BlazeDS. At that time I did not expect that springsource would jump into this the way they do now. I see already two projects
This sounds almost to good to be true. Combining my springframework knowledge with flex and ActionScript. Maybe I should create a flex front-end talking using BlazeDS to a Hippo Back-end. Of course the application is running on OSGi 
Oke, that is something I am not going to talk about in this post. I am going to talk about the new spring flex projects and my first impression. This post is about the BlazeDS integration.

In my previous blog post : integrating flex 3 with spring security I made a good effort to create a nice flex 3 application and integrate authentication and authorization with spring security. A few days a go I received a trackback from sven. Curious as I am I started reading the material he provided and especially the other links he mentioned. That made me think about my own solution. To be honest I think I did not really do a good job. It works, but still not optimal for most of the flex situations.
In my previous post I already mentioned the problem of sessions that are closed and exception handling with respect to security. In this article I am looking at the available mechanisms for security in flex. In this post I explain why I am not really using the flex or better BlazeDS security mechanisms and what you probably should use them for.
If this made you curious enough, read on. If you have questions, remarks or improvements, do not hesitate to use the comments feature of this blog item.

This blog item show a way of doing security, after some additional experience I consider this method as being non optimal. The server side does not change a lot (spring security configuration), but the client does. I explain my current solution is this blog post:Integration spring security and flex 3 the sequel/
This article is actually about two things. It explains the basic steps to use the new spring security version 2 library in a java (web) application. I am going to show the basic configuration as well as web resource authorization and bean methods authorization. The other part is the integration of flex with spring security. I am going to show how to use authentication from within flex 3 using the spring security back end. After that I’ll show a service used from within flex through blazeds to ask for the roles a logged in user has. Using these roles I am going to hide buttons to actions non admin users must not use. Like the create new book. In short this article shows the complete picture of an application using flex 3, blazeds, spring security to authenticate users and authorize actions.
Read on if you want to learn about the integration of these frameworks.

Those who read articles here regularly know by know I use the springframework a lot. It is a very nice framework for creating server side code. Also the spring-mvc project is something I have used a lot. Still it does not help you enough to create those catchy looking graphical user interfaces. Therefore I have working with frameworks like: Google Web Toolkit, Wicket and smaller ajax frameworks like jQuery, DWR, etc. They all have there ways of integrating with springframework. So I write the business functions using the springframework and I can create multiple different user interfaces on top of it. There is at least one tool/framework missing in my list. Well this post is going to change that.
 This post is about FLEX from Adobe. Flex is a very nice framework to create these flashy looking user interfaces with a very rich user interaction experience. Wouldn’t it be nice if we could combine this technology with the so well known server side technology called springframework. Adobe has launched a new product called BlazeDS which is perfectly capable of calling spring managed beans from a flex front end application.
In this post I am going to show you al the steps to create a flex front end with a button to load a bunch of data from the server. This bunch of data is coming from a spring managed bean. The following image gives a schematic view of the application
