Integration with Adobe Flex

[Simon Rommers]

Hello,

Does anyone have expirience with Flex integration?
What libraries do you use? Any gotchas?

Thanks.

I used this website:
http://coenraets.org/flex-spring.

The article suggest to install it and it's not free. For what it seems to bring I would rather go to something like DWR.
Am I right?

Flex Data Services 2 Express edition is free for one CPU. You only have to pay for a license for Flex Builder, which you don't need.

I have recently started working with flex and the spring integration was the first question that came to my mind. What I plan on doing is integrating my flex apps with spring via web services.

I just finished a POC tonight, exposing my Spring middle tier via Xfire webservices in my web tier, secured with acegi. Now that the webservices are properly secured, it should be pretty straight-forward to hook up the flex client.

The only gotcha I ran into with the webservices was not being able to advise my web service implementation class with JSR-181 annotations or the http invoker proxy that it uses to make rpcs to the middle tier. HttpInvokerProxyFactoryBean is a final class, so it can't be advised and Xfire will pick up the annotations from the proxy and try to map it to the url a second time which causes an exception. Consequently, I had to create another class that I could advise for security purposes that I otherwise would not need.

Hi,

I have written a post on Flex and Spring integration. I also have provided an example (zip) which included all the code you need.

You can find the example at my blog.

Hi, the webservices one alternative, but when you have a site that make several queries to the database, this alternative is too expensive. My question is ¿exist other alternative to access to the business tier with remote object? or other capabilitie of flex.

Thanx a lot

It's not Spring related. But it's enough to get you started

I think, better approach would be using BlazeDS or Hessian.
