Premature end of Content-Length delimited message body expected: To make things easier, I’m going to use a Maven archetype Maven 3 recommended:. DefaultServiceInitializer; private function init: Except removing the Tide initialization, we also need to do a small change to Home.
Enterprise RIA with Spring 3, Flex 4 and GraniteDS
Now the Flex application: Project setup We have to start somewhere, and the first step is to create the Spring application. Tutodial can also have a look at the Flex mxml code of the example application generated by the archetype, but for now I will start from scratch. Email Required, but never shown. Other implementations can easily be built for example to retrieve the channels configuration dynamically from a remote file useful with an AIR application for example.

Author” ]public function persistAuthorHandler author: Define a GraniteDS messaging topic in the Spring configuration. New and deleted authors are not propagated automatically, we have to handle these two cases manually.
Adobe Flex is one of the most widely used client technologies for building rich applications and Spring 3 is one of the most popular Java application frameworks. As a first step, we can leverage the Hibernate integration with Bean Validation and simply annotate our entities to let the server handle validation:.
Once again mostly Spring stuff, we just find here the tide-identity bean that is used to integrate Spring Security with the Tide Identity Flex component. Once you change this and redeploy, creating an invalid author has now become impossible but there is error message is a mess that cannot be understood by a real user.
Our application is still missing a critical piece: This can easily be fixed by using the data merge functionality of Tide:. On the Flex side, we can use an editable List note that there is no built-in editable Spark List in Flex 4, so we use a custom ItemRenderer inspired from this blog postsee the full sources attachedand add this:. The archetype already defines a topic named welcomeTopicwe can just reuse it and for example rename it to authorTopic. This level of integration cannot be achieved with a server-only framework.
Even using model-driven code generators to build the Flex application automatically would be easier because there is basically much less code to generate.

The default ObserveAllPublishAll class comes from the archetype and defines a publishing policy where everyone receives everything. As with did with validation, we can in a first step rely on server-side security and simply annotate the service method: Sign up using Facebook.
You can check that you cannot delete an author when logged in as user. Applications can be written faster with a lot less code, and still have a clean architecture with clearly separated layers. Easy Configuration Simplified configuration through runtime scanning of your deployment environment: Finally if you manage to configure Spring Security ACL I won’t even try to show this here, it would require a complete articleyou could use domain object security and secure each author instance separately 8 is the Spring Security ACL bit mask for ‘delete’:.
Indeed we add it from both the data observer and the result handler. Opinions expressed by DZone contributors are their own. This is not very hard, we just have to observe some built-in events dispatched by Tide: AuthorService; [Inject] public var authorService: In the real world we would probably want to apply some MVC pattern instead of a monolithic mxml but this would not change much.
With GraniteDS, you can develop applications for almost any kind of target devices: It’s definitely nicer, but it would be even better if we didn’t have to call the server at all to check for text size.
Without it, nothing will work any more.
