The document outlines the evolution and features of the JBoss Application Server (AS) and its transition towards Java EE6, detailing the release of JBoss AS 6 and AS 7. It discusses key features, architecture improvements, and management capabilities of JBoss AS 7, emphasizing its lightweight and modular design. Additionally, it contrasts the community-driven JBoss AS project with the certified JBoss Enterprise Application Platform (EAP) for enterprise use.

14. AS7 Key Features
• Fast and Lightweight
• Modular, OSGi enabled
• Unified, user focused configuration
• Multiple management interfaces
• Support for multi-node management

15. AS7 Architecture

16. MSC Architecture
Service Builder
Service Registry
Service Controller
Service Deps Value Listeners Injectors
Concurrent Service Container

17. Key attributes of MSC
Small, lightweight, and efficient
•216K JAR, Tiny memory overhead
Highly concurrent & scalable state machine
•State transitions are “tasks”
Services are primarily interface based
•No reflection or XML required!
Only two non-error, non-transition states
•UP & DOWN
Multiple startup modes
•Active, Passive, On-Demand, Lazy, Never

18. #@*%ing fast!

19. Boot Time Results

20. Memory Comparison

21. How is it done?
• Concurrent startup/deployments
• Faster resource lookup/classloading
• Annotation indexing
• Caching reflection metadata
• Lazy loading of (some) services
• StAX based descriptor parsing
• Starting from scratch 

22. Modularity

23. Modularity - JBoss Modules
Small, lightweight, and efficient
•O(1) Dep resolution
•Concurrent class loading (lockless on most VMs)
•207k JAR
“Pure” modular class loading
•Modules only see what they import (includes JDK classes!)
External module definitions
•Don’t have to break open the JAR
Dynamic
•Modules can be redefined
Extensible
•JBoss OSGi implemented on modules

24. modulesorghornetqmainmodule.xml
<module xmlns="urn:jboss:module:1.0" name="org.hornetq">

25. Two Operational Modes
Standalone
•Traditional JBoss single JVM server
•Management facilities IN-VM
•No lifecycle management (only shutdown)
Domain
•Multi-JVM, multi-server model
•Management coordinated by Domain Controller Process
•Multiple server instances (JVMs) per Host
•Full lifecycle managed by Process Controller

</subsystem>

30. Management APIs
• Command Line Interface (CLI)
• Remote Java API
• HTTP/JSON API
• GWT-based console

31. Dynamic Model Representation (DMR)
• Central Detyped Management API
•All management operations operate with/on DMR
•Strictly backwards compatible
• Represents simple and complex types
•int, long, big int, double, big dec, boolean, string, bytes, list,
object, property, expression
• Auto-converts like dynamic languages
• Self describing
• Convertible to/from JSON
• Also has a defined binary protocol (optionally b64)

32. Roadmap
AS 7.0.2 last version of 7.0 series
AS 7.1 – Targeting EE 6 Full Profile
• 7.1 Alpha, really soon
• 7.1 Beta, Oct/2011
• 7.1 CR/Final, end of 2011
JBoss AS 7.1 will be the base for JBoss
Enterprise Application Platform 6 (EAP)

• A Brief History of JBoss AS
• The Path to Java EE6
• JBoss AS6
• JBoss AS7
• Enterprise Application Platform 6 (EAP)
