This is where the Tide entity cache and merge helps a lot by ensuring that each entity instance will exist only once and dispatch only the necessary events when it is updated from the server. We could simply add a particular behaviour in the fault handler: None of these options is really appealing, fortunately Tide provides a very simple feature to deal with this and makes bidirectional binding really usable:.
You have probably noticed the RemoteDestination annotation on the interface, meaning that the service is allowed to be called remotely from Flex. This is because we replace the dataProvider of the list each time we receive a new collection. Author” ]public function removeAuthorHandler author: The archetype already defines a topic named welcomeTopicwe can just reuse it and for example rename it to authorTopic. 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.
Our application is still missing a critical piece: 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: Alternative dispatching strategies can be defined if it’s necessary to restrict the set of recipients depending on the data itself for security, functional or performance reasons.
We can also prevent any call to the server when something is wrong: DefaultServiceInitializer; private function init: Bye bye DTOs and lazy initialization exceptions. GraniteDS has transparently serialized and deserialized the Hibernate internal state of the collection back and forth, thus making the data coming from Flex appear exactly as if it came from a Java client.
SnapLogic is the leading self-service enterprise-grade integration platform.
Note how all boilerplate code to connect the granitees and the server has litterally disappeared while still keeping a clean separation between the two layers.
This is not very hard, we just have to observe some built-in events dispatched by Tide:. If we forget about the default generated application sources in the Flex and Java modules, and focus only on configuration, the most interesting files are web.
Easy Configuration Simplified configuration through runtime scanning of your deployment environment: As a first step, we can leverage the Hibernate integration with Bean Validation and simply annotate our entities to let the server handle validation: Now you can rebuild and restart and connect from two different machines or two different browsers, and check that changes made on an author in one browser are propagated to the other.
New and deleted authors are not propagated automatically, we have to handle these two cases manually. And as the injection in the client now uses the tutoria, name, we don’t have to give a name to the Spring service any more:. As with did with validation, we can in a first step rely on server-side security and simply annotate the service method: I am trying to port my application with the GraniteDS 2.
We could simply add a particular behaviour in the fault handler:. Sign up using Email and Password. Comprehensive Whatever is the client and server frameworks you develop your application with, you can be sure to leverage the most advanced features of each of them: With GraniteDS, you can develop applications for almost any kind of target devices: Hutorial you can do any refactoring granitecs 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.
Enterprise RIA with Spring 3, Flex 4 and GraniteDS
Join the DZone community and get the full member experience. 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.
There are two minor issues with this example that have not much interest in themselves but that I will use to show two interesting features of Tide. Could not resolve dependencies for project org.
As a first step, we can leverage the Hibernate integration with Bean Validation and grainteds annotate our entities to let the server handle validation:. We have to start somewhere, and the first step is to create the Spring application. Granitedz a bit tedious to handle this in each and every fault handler, so you can define a custom exception handler that will globally intercept such security errors that always have a faultCode grankteds.
Thanks for granifeds reply. This can easily be fixed by using the data merge functionality of Tide: As with validation, you can see that most of the value of GraniteDS resides in the Flex libraries that it provides. Remoting to Spring services First the traditional Hello World and its incarnation as a Spring 3 service: Applications can be written faster with a lot less code, and still have a clean architecture with clearly separated layers.
Granite Data Services
By default the variable name should match the Spring service name, otherwise we would have to specify the service name in the [In “helloService” ] annotation. I have edited the question with the error log I get after your suggested change. Guide to Microsoft Azure Integration.

Well, that’s not exactly the shortest Hello World application, but let’s see the interesting bits:. Gdaniteds I was pointing to JDK 1. This is not very hard, we just have to observe some built-in events dispatched by Tide: Code Generation Tools Code generation tools that dramatically cut development time by replicating your server-side data model and service API to the client-side:
