Thanks to our friends from onlinescam. This is grxniteds log after I made the change you suggested. This is a simple CRUD application using some very convenient Flex 4 features such as states and bidirectional data binding.
And as the injection in the client now uses the interface name, we don’t have to give a name to the Spring service any more:.
I am trying to port my application with the GraniteDS 2. We can also prevent any call to the server when something is wrong:. Once again all the usual boilerplate code necessary to deal with data and collections has completely disappeared.
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. The important thing is that the Flex and Java parts do not contain useless or redundant code and are thus a lot easier to maintain.
Our application is still missing a critical piece: This may seem granitrds a ‘magic’ injection but as we asked for an instance of Component, the framework knows for sure that you want a client proxy for a remote bean. The default ObserveAllPublishAll class comes from the archetype and defines a publishing policy where everyone receives everything. These two technologies make a great combination for building enterprise applications with a modern looking and rich user interface.
This looks like a minor cosmetic change, but now you benefit from code completion in your IDE and from better error checking by the Flex compiler. In the Flex module pom. A client development framework Tide that brings familiar Java EE concepts to the client uttorial All visual features of Flex highly depend on the object instance that drives the effect and the events that it dispatches.
Guide to Microsoft Azure Integration. The error message is handled by our fault handler and displayed as an alert. As a first granitees, we can leverage the Hibernate integration with Bean Validation and simply annotate our entities to let the server handle validation:. DefaultServiceInitializer; [Bindable] [Inject] public var identity: It has been yutorial out-of-the-box integration with Spring very early and this integration has continually been improved with each new version of GraniteDS, following a few core principles:.
Well, that’s not exactly the shortest Hello World application, but let’s see the interesting bits:. Define a GraniteDS messaging topic in the Spring configuration.
Now you can do any refactoring you want on the Java side, like changing method signatures, Gas3 will then regenerate the AS3 proxies and the Flex compiler will immediately tell you what’s wrong. With the help of our Tide framework, it only costs a Java annotation to enable concurrent modifications to be instantly dispatched to all connected clients.
Code generation tools that dramatically cut development time by replicating your server-side data model and service API to the client-side: You can check that you cannot delete an author turorial logged in as user. Granitecs the Flex application: Now we would like to prevent non-administrator users from deleting authors.

We could simply add a particular behaviour in the fault handler:. It simply calls a remote method on the client proxy with the required arguments and provide callbacks for result and fault events, much like jQueryso you don’t have to deal manually with event listeners, asynchronous tokens, responders and all the joys of RemoteObject.
Once again we use the handy Flex 4 states to display the login form or the application, and bind the current state to the Tide Identity component loggedIn property that represents the current authentication state. All is good, but anyone can modify anything on our ultra critical book database, so it’s time to add a bit of security. Author” ]public function removeAuthorHandler author: Going even further, the whole injection can be made completely typesafe and not rely on the service name any more by using the annotation [Inject] instead of [In] note that we can now give our injected variable any name: The main thing concerning GraniteDS is the flex-filter declaration.
We can also prevent any call to the server when something is wrong: GraniteDS is based on a cleanroom implementation of the AMF3 remoting and messaging protocols, and has been historically the first open source implementation of the AMF3 protocol in Java.
The last thing I will demonstrate is the ability to dispatch updates on an entity to all connected clients. That’s also why this is necessary to configure different servlet implementations depending on the target container Tomcat, JBossWeb GraniteDS detects automatically most of the Spring configuration at startup and configures itself accordingly, so these 10 lines of XML are generally enough for most projects.
Both entities extends AbstractEntitybut it is not mandatory at all, it’s just a helper class provided by the Maven archetype. HelloService;private function hello name: Applications can be written faster with a lot less code, and still have a clean architecture with clearly separated layers.
Over a million developers have joined DZone. If you remind of the Spring security configuration, it’s the client counterpart of the tide-identity component we declared there.

Now rebuild and run the application on Jetty, and check that you can create, update and delete authors. I have edited the question with the error log I get after your suggested change.
The init method is called in the preinitialize handler. 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: New and deleted authors are not propagated automatically, we have to handle these two cases manually.
