Open source implementation of the Java EE suite of services

Great deal of customization due to modularization of the services like.

◦ Enterprise JavaBeans (EJB)◦ Java Persistence API (JPA)◦ Java Messaging Service (JMS)◦ Java Transaction Service/Java Transaction API (JTS/JTA)◦ Servlets and JavaServer Pages (JSP)◦ Java Naming and Directory Interface (JNDI)

Advanced and fully extensible, cross component model, aspect integration, server runtime environment

Community Jboss Application Server and Jboss Enterprise Application Platform.

JBoss Introduction

http://weblogic-wonders.com

Page 4: What is JBoss  JBoss Architecture  JBoss Internals  JBoss Installation  Directory Structure  Jboss Enterprise Application Platform  Starting

Developed by Jboss Inc, now a RedHat division.

JBoss AS 4.0, a Java EE 1.4 features embedded apache tomcat.

JBoss AS 4.2 also functions as a Java EE 1.4 but deploys EJB 3.0 by default

JBoss AS 5.1, released as of 2009, operates as a Java EE 5 application server built on top of a new JBoss microcontainer.

JBoss AS 6.0, an unofficial implementation of Java EE 6, was released on December 28, 2010. JBoss AS 6 does not support the full Java EE 6 stack

JBoss AS 7, the current stable release, was released on July 12, 2011.

JBoss Server : History

Community Jboss Application Server:

Used by developers to test and integrate middleware capabilities. Best suited for early to advanced prototyping and development http://www.jboss.org/jbossas/downloads/

Jboss Enterprise Application Platform:

Integrates JBoss Application Server, with JBoss Hibernate, JBoss Seam, and other leading open source Java technologies from JBoss.org into a complete, simple enterprise solution for Java applications.

Integrated, tested and certified Enterprise Platforms. Evaluation copy : http://www.jboss.com/downloads/ http://

Jboss Microcontroller : POJO based kernel ,wires all the services. Core of the server.

Full support for EJB 3.0

JBoss Messaging is a high performance JMS provider, rewrite of JBossMQ.

JBossCache enhancing the performance for caching the data

JBossWS is the web services stack for JBoss 5 providing Java EE compatible web services,

JBoss Transactions is the default transaction manager for JBoss 5.

JBoss Web is the Web container in JBoss 5, an implementation based on Apache Tomcat that includes the Apache Portable Runtime (APR).

JBoss Security has been updated to support pluggable authorization models including SAML, XACML and federation

Jboss EAP – Core components

Crux of Jboss, which is the foundation architecture into which you can plug only the services that your application needs

You can use bean configuration files in the server/xxx/conf directory to configure the MicroContainer.

Jboss 5.0 still provides few services based on JMX (Java Management eXtensions) to access the MBeans.

JMX Service is defined by JMX kernel is server/xxx/conf/jboss-service.xml, some Mbeans defined are below.

◦ The logging Service◦ The Thread Pool - used to supply threads to run various services◦ The Java Naming and Directory Interface - JNDI◦ Various MBeans for managing security - includes JAAS◦ Various MBeans related to accessing JMX services◦ Various MBeans related to the remoting service

Higher server performance, as native operating system code becomes available for the server to optimize tasks.

Apache Portable Runtime (APR)

OpenSSL for implementing SSL and TLS

Tomcat Native (TC-Native)

mod_jk connects the Tomcat JSP container to the Apache webserver, providing load-balancing.

mod_cluster is an httpd-based load balancer.

ISAPI is a connector for the Microsoft IIS web server.

HornetQ a JMS messaging provider which provides high performance

Server Profile Directory Structure

Conf :Contains the bootstrap.xml bootstrap descriptor file for a given server configuration. This defines the core microcontainer beans.

Data: Used by services that want to store content in the file system. It holds persistent data for services intended to survive a server restart.

Deploy: Contains the hot-deployable services, applications

Lib: Contains library files specific to the server configuration.

Log: This is where the log files are written

tmp Used for temporary storage by JBoss services. The deployer, for example, expands application archives in this director

Work: Directory is used by Tomcat for compilation of JSP

Page 14: What is JBoss  JBoss Architecture  JBoss Internals  JBoss Installation  Directory Structure  Jboss Enterprise Application Platform  Starting

Starting the Server: Move to JBOSS_DIST/jboss-as/bin directory and execute the run.bat (for

Windows) or run.sh (for Linux) script, as appropriate for your operating system. $JBOSS_HOME/bin/run.bat

Note: Below are the default settings. The server is bound to 127.0.0.1 for security reasons. To enable remote access

by binding JBoss services to a particular interface, simply run jboss with the -b option. $JBOSS_HOME/bin/run.bat –b

The server runs on port 8080 and to change the settings, we can run it as below. $JBOSS_HOME/bin/ run -Djboss.service.binding.set=ports-01

Specify alternate server profile. $JBOSS_HOME/bin/ run –c <alternate-server-profile>

Stopping the server: You can run the shutdown script to shutdown the server.

$JBOSS_HOME/bin/shutdown.sh

JBoss server Start / Stop.

Start automatically when you boot a Windows host computer

JBoss AS comes with Windows service executable as part of Jboss Native library that can run JBoss Application Server as service.

The service executable jbosssvc.exe transforms run.bat and  shutdown.bat batch scripts to services. This means that any change made to those scripts will be used both in service and command line mode.

Jboss Logging

In JBoss log4j is used for logging.

Controlled by <server-profile>/conf/jboss-log4j.xml file.

Defines different appenders, message format, log levels etc.

By default, JBoss produces output to both the console and a log file (log/server.log).

Console default level is INFO.

No default log level for server log, so everything is logged (DEBUG).

<appender name="FILE" class="org.jboss.logging.appender.DailyRollingFileAppender">

<errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>

<!-- <param name="File" value="${jboss.server.log.dir}/server.log"/> -->

<param name="File" value="C:/server.log"/>

<param name="Append" value="true"/>
