1. Introduction to the JBoss Presented by: Hao Shi

2. Agenda Application Servers What is JBoss JBoss features Architecture of JBoss Installation and running the server Testing the installation

3. Application Servers 1.Provide a runtime for mission-critical applications; 2.Solve the many (client) to Few (resources) problem; 3.User code does not have to deal with: - security - Transactions -Threading - Pooling - Clustering - Caching - Connectors - Messaging - ……

4. What is JBoss  An open source J2EE server;  Founded by Marc Fleury in 1999;  Backed by a community of developers;  Yet another Java AppServer.

5. What made JBoss Special  Free, open-source product; professional supporting, consulting, and training - Commercial Servers at $10k - $100k  LGPL licensed - Free use/Distribute/Embed  Developer friendly - No pre – compilation steps, etc  Innovative design - Lightweight, modular, dynamic

6. Architectural Innovations The JBoss Microkernel - A light weight component framework that wires together a set of services; - Services are de-coupled, innovations are routed through an internal bus;

7. Architectural Innovations  Aspect Oriented Design - Interceptors applied using Dynamic Proxies and traditional OOD techniques;  Instant Clustering;

8. JBoss Microcontainer The JBoss Microcontainer is a refactoring of JBoss's JMX Microkernel to support direct POJO deployment and standalone use outside the JBoss application server. - All the features of the JMX Microkernel - Direct POJO deployment (no need for Standard/XMBean or MBeanProxy) - Direct IOC style dependency injection - Improved lifecycle management - Additional control over dependencies - Transparent AOP integration - Virtual File System - Virtual Deployment Framework - OSGi classloading

9. Jboss Today  Most used application server in Development;  20 million downloads;  Large jboss.org community; - 250,000+ users; - 500+ contributors, over time, ~30 at any time; - 300,000 forum posts; - x10 bigger community than any open source server;

10. JBoss AS 5  JEE 5 certified application server;  Based on POJO Microcontainer; - Aspectized light weight IoC container; - JMX stays, become an aspect of POJO services;  New implementations of core services; - JBoss messaging; - JBoss transactions;  JBoss SEAM;  JBoss webserver (Tomcat on steroids);

11. Installing JBoss AS  Prerequisites: - JDK 1.5 or above - JAVA_HOME environment variable pointing to JDK  Download the JBoss AS you want to install: http://www.jboss.org/jbossas/download Platform Independent Zip Archive  Extract the archive in the directory you choose  Run ( For Windows, run.bat, for Linux, run.sh);

12. Alternative Installation: JEMS  GUI Installer utility  Run through Java Wed Start or download and run locally: - http://www.jboss.org/jemsinstaller/downloadshttp://www.jboss.org/jemsinstaller/downloads - ‘java -jar jems-installer-1.2.1.CR4.jar’  Choose between different profiles; - All, Default, Minimal - EJB3, EJB3 clustered  Customize services installed;  Secure admin consoles;

13. Directory Structure /binStartup/Shutdown Script /clientClient-side jars need to communicate with JBoss /docsConfiguration file DTD’s, licenses, schemas data source configuration examples /libMicrokernel libraries Do not pub your application library here /serverServer configurations

14. Server Configuration Structure /confJboss static configuration files Jboss service.xml: bootstrap config file for JMX microkernel /dataUsed by services requiring permanent storage (hypersonic, JBossMQ, SFSB..) /deployDefault location monitored by hot development service, Put your application archive here /libStatic java library directory. Libraries are loaded in the shared class path server startup. /logDirectory for Jboss log files /tmp, /work Temporary directories

15. Start the server To launch an instance of JBoss run [–c ] if –c parameter is not specified, default configuration is used

16. Microkernel benefits for SOA architecture Microkernel approach ideal for ISV and OEM  Easily remove the services you don’t need  Tight footprint and modular codebase and hot deploy/remove/redeploy  JBoss is a TRUE Service Oriented Architecture (SOA)

17. Microkernel benefits for SOA architecture

18. Deployers: Working from the Network

20. Tomcat standalone or Tomcat inside JBoss ? Better JBoss deployer  Hot deployment  Deployment of nested archives (EARs, SARs)  Redeployment  Automatic undeployment Advanced clustering Integrated J2EE stack within one VM  Deployment descriptor  Optimized local calls  Integrated security AOP in JBoss 4.0 available in Tomcat components and webapps Easy to use class loader Nukes

21. JBoss IDE JBoss IDE is based on Eclipse.  Series of plugins for Eclipse The debugging and monitoring of JBoss servers and the control of their life cycle (start/stop). A very comfortable and sophisticated support for XDoclet  Support completion and generation  Support for AOP (completion and generation). An easy way to configure and deploy the packaging layout of archives (packed or exploded)

22. Thank You.
