Last week I've shown you how to connect a Flex application to a java Spring application using BlazeDS. As you might have read everywhere changing your Flex web application to an Air client side application is very easy. So let's take our Flex application that is connecting to our Spring application using BlazeDS and change it to an AIR application working exactly the same. I'm using the sources here that were created in the posts BlazeDS and Spring First what we need to do is create a new AIR project in Flex, so let's start with creating a new Flex project and on the first page of the wizard there change the setting to Desktop Application.

I've been asked by a publisher to write a book about Flex and Java integration, at this point I'm working on the different subjects that should be covered in the book, so if any of you have any suggestions or requests please let me know and I'll see if I can use them in the book, any requests on Flex, Java that have to do with one of the two are welcome.

Let's do the last part of our demo, this is the Flex part on the client that we want connected. First we finish the application with our logon, we logged on, and sent our username to the server, so now all we need to do is subscribe to receive tasks from the other Flex client. To do this we add a consumer tag to our code and subscribe to messages on the server.

Let's continue with our application setup. Now this part of the Java application is done, we can continue with the rest of the application. First let's continue with adding our settings to Blaze DS so we can make our communication work, after that we'll start with the Flex part and get the entire application working. Our Spring and Hibernate part is done already so as soon as we have the rest connected this should be working.

Ok let's continue, now let's see what we want to send over the line, for our application, first when a user fills in it's username we'll send a string to the server containing this username. Since we don't want to use with strings, the next thing we are going to do is find a user object on the server and send this back to the client to tell the client that this user is connected. Last thing in the demo we want to send over the line now is a task object as soon as that is created so it can be shown at the task list of the user.

As promised yesterday during my J-Spring session I would post the code of the demo application online. Since it was a long day yesterday and I've been training all day today I couldn't find the time to do it before now, so sorry for the delay. Let's start first with what you need to get started. First let's start with getting Blaze Ds from the Adobe site. After that it might help to have FlexBuilder or just the Flex SDK to compile the application at the end.

Today the FLUGR, dutch Flex user group site has been released. Tomorrow it will be publicly announced at the J-Spring event. This is a site for FLEX, AIR, Blaze DS developers. The content will mostly be directed about these subjects and anything that has to do with using these programs including the integration with a lot of different back end systems like Java, ColdFusion and Ruby. The user group will be hosting it's first event in June of this year. For more information check http://www.flugr.nl

After spending the evening on a demo application for the J-Spring next week where I'm going to give a presentation about Blaze DS, Spring, Hibernate and Flex it's done for the biggest part. The most projects I've worked on so far used LCDS (LiveCycle Data Services) so again it was some getting used to, but we have the most important part working now. Biggest difference again is that the RTMP is not available in Blaze. This is the Real Time Messaging Protocol that is available in LCDS.

Seems like we have it all working now, the last part of the working form is done, what I did for my form is set the build folder to a new folder in the webroot. This folder is flexblog. So now all I have to do is instead of pointing my code to the addcomment.cfm I just have to point it to flexblog/Comments.cfm

Now that we seem to have everything working the way it should we can continue to the next part, this next part is submitting the data to the server and do all server related actions needed to post the comment and notify everyone that needs to be notified of this update. Of course for this we have to change the CFC on the server again and make a call to get this all done.
