GraniteDS does not support the standard Consumer and Producer Flex messaging API

its own client implementations of these classes org.granite.gravity.Consumer and org.granite.gravity.Producer that provide very similar functionality

most advanced features and greatly simplifies asynchronous handling and client data management

preferred for new projects

Server Options

two options

RemoteObject API,

GraniteDS support for externalization of lazily loaded JPA entities/collections, and support for scalable messaging though Gravity

Tide API

full feature set of Tide data management and further integration with data push through Gravity

complete support for Spring and Seam security or integration with CDI events

Tide/CDI/JPA2/Java EE 6 on JBoss 6/7 or GlassFish 3

If you are on a Java EE 6 compliant application server, it is definitely the best option

 logout() 

An implementation of this interface must be thread safe

If authorization fails, either because the user is not logged in or because it doesn't have required rights, it must throw an appropriate org.granite.messaging.service.security.SecurityServiceException.

Writing a Security Service

nothing to do with a true Flex destination

only one instance of this service is used in the entire web-app and will be called by concurrent threads

This method is called upon each and every service method call invocations (RemoteObject) or subscribe/publish actions (Consumer/Producer). When used with RemoteObjects, the authorize method is responsible for checking security, calling the service method, and returning the corresponding result.

default implementation of this method in AbstractSecurityService is to do nothing

security services are not exposed to outside calls

support for CDI is included in the library granite-cdi.jar

10.1. Configuration with Servlet 3 On Servlet 3 compliant containers, GraniteDS can use the new APIs to automatically register its own servlets and filters and thus does not need any particular configuration in web.xml. This automatic setup is triggered when GraniteDS finds a class annotated with @FlexFilter in one of the application archives:

@FlexFilter(configProvider=CDIConfigProvider.class) public class GraniteConfig { }  

list of annotation names that enable remote access to CDI beans

@FlexFilter declaration will setup an AMF processor for the specified url pattern

@RemoteDestination

always declared by default

10.3.2. Typesafe Remoting with Dependency Injection

It is possible to benefit from even more type safety by using the annotation [Inject] instead of In. When using this annotation, the full class name is used to find the target bean in the CDI context instead of the bean name.

summary of templates used by the generator depending on the kind of Java class it encounters:

these templates are bundled in the granite-generator.jar archive, in the org.granite.generator.template package and accessible as resources via the class loader

class: protocol is used because all standard templates are available in the classpath

Alternatively, you may use the file: protocol to load your template from the filesystem. These templates can be specified either by using absolute paths (eg. file:/absolute/path/to/mytemplate.gsp) or paths relative to your current Eclipse project root directory (eg. path/to/mytemplate.gsp).

ActionScript 3 generator is able to write AS3 typed client proxies for exposed remote services

Compared to the usual Flex RemoteObject, this can greatly help development by bringing

in Flex when using remote services.

 Known Limitations

Gas3 does not support inner classes

must declare your classes in separated source files if you want them to be correctly handled by the generator

 enabled="{identity.hasRole('admin')}"

button labeled Delete will be enabled only if the user has the role admin
