un ensemble de patterns se dégage des principes J2EE, en voici la cartographie :
et une courte description de l'ensemble de ces patterns (en anglais pour l'instant, désolé) :
Presentation Tiers Patterns
Intercepting Filter : Facilitates preprocessing and postprocessing of a request
Front Controller : Provides a centralized controller for a request handling
Context Object : Encapsulates state in a protocol independent way to be shared throughout your application
Application Controller : Centralizes and modularizes action and view management
View Helper : Separates processing logic from view
Composite View : Creates a composite view from subviews by separating content and layout management
Service to Worker : Invokes business processing prior to view processing
Dispatch View : Invokes View Processing Prior to business processing
Business Tier Patterns
Business Delegate : Encapsulates access to a businness service
Service Locator : Centralizes lookup logic for business services anc components
Session Facade : Expose coarse-grained services to remote clients
Application Service : Aggregates behavior to provide a uniform service layer
Business Object : Encapsulates business data and logic
Composite Entity : Implements persistent business objects using entity beans
Transfer Object : Carries data accross a tier
Transfer Object Assembler : Assembles a transfer object from multiple data sources
Value List Handler : Manages search and iteration of large set of results
Integration Tier Patterns
Data Access Object : Abstracts and encapsulates access to persistent store
Service Activator : Provides asynchronous access to one or more services
Domain Store : Provides transparent persistence for business objects
Web Service Broker : Exposes one or more services using XML and web protocols
