graniteds Tide documentation

shared by kuni katsuya on 09 Aug 12 - No Cached
  • GDS/Tide project represents the Data Services part of GDS
  • comparable to LiveCycle Data Services, which is neither open source nor free, as it provides similar features such as client container of managed entities, data paging, and integration with server components, but it is based on completely different principles:
  • strongly typed Hibernate/JPA detached objects
  • ...5 more annotations...
  • All managed entity instances are unique in a Tide context
  • Tide keeps the classic three layers web architecture, when LCDS removes the service layer, and is some kind of remote JPA provider for Flex applications
  • Tide approach is to minimize the amount of code needed to make things work between the client and the server
  • principles are very similar to the ones of JBoss Seam, which is the main reason why the first integration of Tide has been done with this framework. Integrations with Spring, EJB 3 and CDI are also available
  • need to compile your MXML/AS sources with the granite-essentials.swc and granite.swc libraries

  • @MappedSuperclass
  • Important things on ID/UID
  • entity lives in three layers:
  • Flex client
  • JPA persistence context
  • database
  • When updating existing entities coming from the database
  • id is defined and is maintained in the three layers during the different serialization/persistence operations
  • when a new entity is being created in any of the two upper layers (Flex/JPA)
  • new entity has no id until it has been persisted to the database
  • most common solution is to
  • have a second persisted id, the uid
  • which is created by the client and persisted along with the entity
  • recommended approach to avoid any kind of subtle problems is to have a real uid property which will be persisted in the database but is not a primary key for efficiency concerns
  • You can now ask Tide to
  • limit the object graph before sending it
  • Flex with the following API :
  • EntityGraphUnintializer
  • uninitializeEntityGraph
  • Person object will be uninitialized
  • uperson contains
  • only the minimum of data
  • to correctly merge your changes in the server persistence context
  • Tide uses the
  • client data tracking
  • to determine which parts of the graph need to be sent
  • Calling the EntityGraphUninitializer manually is a bit tedious and ugly, so there is a cleaner possibility when you are using generated typesafe service proxies
  • annotate your service method arguments with @org.granite.tide.data.Lazy :
  • @Lazy
  • take care that you have added the [Lazy] annotation to your Flex metadata compilation configuration
  • in the Flex application, register the UninitializeArgumentPreprocessor component in Tide as follows :
  • [UninitializeArgumentPreprocessor]
  • all calls to PersonService.save() will
  • automatically use a properly uninitialized version
  • of the person argument.
  • 15.4. Dirty Checking and Conflict Handling
  • simplify the handling of data between Flex and Java EE
  • Chapter 15. Data Management
  • Tide maintains a client-side cache of entity instances and ensures that every instance is unique in the Flex client context
  •  uid().hashCode();
  • Tide currently only supports Integer or Long version fields, not timestamps and that the field must be nullable
  • in a multi-tier environment (@Version annotation)
  • highly recommended to use
  • JPA optimistic locking
  • highly recommended to add a
  • persistent uid field
  • AbstractEntity
  • in general this identifier will be
  • initialized from Flex
  • @Column(name="ENTITY_UID", unique=true, nullable=false, updatable=false, length=36)     private String uid;
  • @Version     private Integer version;
  • uid().equals(((AbstractEntity)o).uid())
  • consistent identifier through all application layers
  • @PrePersist

  • Dirty Checking and Conflict Handling
  • entity instance can be in two states :
  • Stable
  • Dirty
  • property meta_dirty is
  • bindable
  • could be used
  • to enable/disable a Save button
  • correct way of knowing if any object has been changed in the context, is to use the property meta_dirty of the Tide context
  • tideContext.meta_dirty
  • reliable when using optimistic locking
  • check that its @Version field has been incremented

  • standard Flex RemoteObject API
  • ...16 more annotations...
  • 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
  • Tide remoting API with the GraniteDS/Tide server framework integration
  • most advanced features and greatly simplifies asynchronous handling and client data management
  • preferred for new projects
  • Server Options
  • two options
  • GraniteDS service factory
  • RemoteObject API,
  • GraniteDS support for externalization of lazily loaded JPA entities/collections, and support for scalable messaging though Gravity
  • GraniteDS/Tide service factory
  • 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

  • Data Management
  • Tide maintains a client-side cache of entity instances and ensures that every instance is unique in the Flex client context
  • Tide provides an integration between the Flex/LCDS concept of managed entities and the server persistence context (JPA or Hibernate).
  • ...10 more annotations...
  • All entities marked as [Managed] are considered as corresponding to Hibernate/JPA managed entities on the server
  • It is highly recommended to use JPA optimistic locking in a multi-tier environment (@Version annotation
  • In conclusion, the recommended approach to avoid any kind of subtle problems is to have a real uid property which will be persisted in the database
  • but is not a primary key for efficiency concerns
  • Here all loaded collections of the Person object will be uninitialized so uperson contains only the minimum of data to correctly merge your changes in the server persistence context
  • Tide uses the client data tracking (the same used for dirty checking, see below) to determine which parts of the graph need to be sent.
  • Dirty Checking and Conflict Handling
  • Data Validation
  • Tide integrates with Hibernate Validator 3.x and the Bean Validation API (JSR 303) implementations, and propagate the server validation errors to the client UI components
  • Data Paging

  • ...5 more annotations...
  • highly recommended to use JPA optimistic locking in a multi-tier environment (@Version annotation)
  • Tip The easiest and recommended way for getting Tide enabled managed entities is to generate them from Java classes with Gas3 or the GDS Eclipse builder using the Tide="true" option.
  • In a typical Flex/app server/database application, an entity lives in three layers: the Flex client the Hibernate/JPA persistence context the database
  • only invariant is the id.
  • id reliably links the different existing versions of the entity in the three layers

shared by kuni katsuya on 08 Aug 12 - No Cached
  • In order to initialize GDS/Tide for CDI and Hibernate, you must add granite.jar, granite-hibernate.jar and granite-cdi.jar to your WEB-INF/lib
  • The easiest way to add GraniteDS support to a CDI project in a Servlet 3 compliant container (currently only GlassFish v3) is by adding a configuration class in your project. This class will be scanned by the servlet 3 container and GraniteDS will use the annotation parameters to determine the application configuration
  • GraniteConfig.java import org.granite.config.servlet3.FlexFilter; import org.granite.gravity.config.AbstractMessagingDestination; import org.granite.gravity.config.servlet3.MessagingDestination; import org.granite.tide.cdi.CDIServiceFactory; import org.granite.tide.cdi.Identity; @FlexFilter( tide=true, type="cdi", factoryClass=CDIServiceFactory.class, tideInterfaces={Identity.class} ) public class GraniteConfig { }

  • GraniteDS also integrates with container security for authentication and role-based authorization
  • ...37 more annotations...
  • always have to include this library in either WEB-INF/lib
  • 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
  • ConfigProvider
  • override these values by setting them in the annotation properties
  • tide=true,         type="cdi",         factoryClass=CDIServiceFactory.class,         tideInterfaces={Identity.class}
  • @FlexFilter declaration will setup an AMF processor for the specified url pattern
  • tideAnnotations
  • defines suitable default values
  • @TideEnabled
  • @RemoteDestination
  • always declared by default
  • tideInterfaces
  • tideRoles
  • exceptionConverters
  • amf3MessageInterceptor
  • 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.
