Overview

 The JBoss for Advanced J2EE Developers course is required for individuals who wish to become Certified JBoss Developers. This course provides the necessary knowledge regarding the implementation of the JBoss microkernel, the JBoss security framework, and interceptor based approach to building component containers.

 This course is targeted toward J2EE professionals who wish to take advantage of the JBoss Application Server internal architecture to enhance the functionality and performance of J2EE applications on the JBoss Application Server. This course covers topics such as JMX and those beyond the J2EE specification such as Microkernel architecture, Security, Clustering, and Fine Tuning.

Prerequisites

It is highly recommended that students either complete the JBoss for Java Developers course OR take the Middleware Placement Exam prior to registering for the JBoss for Advanced J2EE Developers course. The developer should have practical experience with each of the following topics:

• JNDI
• JDBC
• Servlets and JSPs
• Enterprise Java Beans
• JMS
• The J2EE Security Model
• J2EE application development and deployment on the JBoss Application
• Experience with ANT and XDoclet or similar technologies.

While prior knowledge of JMX is helpful, it is not required. This training is based on the 4.x series of the JBoss Application Server.

Course outline

 

1. JBoss State of the Union. In this brief introduction we present JBoss the Open

Source project and JBoss Inc. the provider of Professional Open Source

services. We establish the current status of the project and cover the product

roadmaps planned for the next JBoss product releases. We will tell you where we

are today, and where we plan to go tomorrow.

2. JBoss Architecture Overview. The JBoss architectural overview paints the full

picture of the app-server microkernel design -- the JMX invocation bus, MBeans

as services and containers. We briefly focus on the containers and then back

some more to the unified classloader architecture, before getting to the multiple

detached invoker layer and the client proxy tricks. This module is a must

requirement for any systems architect looking to understand the modular nature

of the application server, how to take advantage of customized solutions with

JBoss and where to find the extensions point to mold the server to fit your

application’s needs.

  3. JMX in JBoss. In this module we go in depth into the JMX specification,

standard/dynamic and model MBeans covering the XMBeans implementation of

JBoss. This focuses on the usage of JMX and where we apply it in the

application server. You will learn how to create management interfaces for your

service implementations, how to decouple your services running in the

application server and how to externalize the service definitions. We will show

how to take advantage of additional JMX service such as persistence in this

section. Core and fundamental knowledge to any developer looking to build

customization and extensions to the application server.

 4. JBoss Microkernel. Creating extensions and new modules is easy with the JMX

based service definition in the JBoss application server. This module explains

how you integrate your own custom modules into the JBoss microkernel. We

cover the deployer architecture and implementation, classloader architecture and

how to integrate your custom classloaders into the JBoss classloading domains.

We will show you how we bootstrap the application server with practical tips on

how to use the JMX API and most importantly, how to implement your own

service implementations and have them participate as first class application

server modules in the kernel lifecycle. Anyone wishing to extend the application

server to fit their specific application requirements must understand how to take

advantage of the kernel integration.

 5. JBoss Smart Proxies. In this section you will fully understand how the dynamic

proxy approach of JBoss application server works. Learn how to customize the

proxy implementations executed by the client applications, how to take

advantage of the location dependent information inside the proxy and how to

customize the on-the-wire payload sent by the client to the application server. For

developers looking to extend the transparent wire protocol of the proxy with

additional security or identity context, understanding the smart proxy architecture

is vital.

6. EJB Container. In this module we will walk you through the EJB container

implementation. We will show how the interceptor based middleware design

allows your server to be configured as an EJB container, how each of the

individual interceptors implements a specific aspect of the EJB specification, and

how an EJB invocation travels through the interceptor stack to execute the bean

logic. Essential information to anyone who needs to understand how to interact

with the abstracted invocation object, how to implement interceptors on the

server side, how to integrate with different server side services, such as

transaction manager and security manager, and how to customize or optimize

the EJB container itself.

 7. Introduction to EJB3. This module introduces you to the next generation of

J2EE application development using the EJB3 component model. We will cover

the major new features of the EJB3 specification and show you how the new

component model allows middleware developers to build their applications with

regular Java objects. Java 5 annotations, POJO based EJBs, EJB callbacks and

EJB specification defined interceptors will be introduced in this module. We will

also introduce the major new features to EJB persistence, new POJO based

entity beans and persistence with inheritance and polymorphism. This module

gives you a head-start in understanding what the new specification brings to the

table and how it affects future EJB deployments.

 8. Aspect Oriented Middleware. This brand new module takes you to the future of

Java middleware development. Expanding on the topics covered with earlier

sections, we generalize the interception architecture and define JBoss AOP

framework, and show you how to build your custom containers from scratch in a

robust and predictable manner. We explain basic AOP concepts such as

aspects, pointcuts and bindings and show how to use those in practice to

implement a POJO based middleware applications. We will also cover how to

apply existing EJB related services (security, transactions, locking, etc) on plain

old Java objects, and how to turn your existing domain objects into fully blown

containers without imposing disruptive component contracts to the

implementation.

9. JBossCache. Learn how to use and take advantage of industrial strength

distributed cache implementation from JBoss. JBoss Cache is a replicated and

transactional cache that allows you to cache data from Enterprise Applications in

order to dramatically improve performance. The caching data is replicated

automatically allowing you to easily cluster data across a grid of JBoss servers.

JBoss Cache can run as an MBean service within JBoss Application Server or

other J2EE containers. We cover both the TreeCache implementation and the

AOP enhanced cache implementation – features and automatic object mapping

(with AOP TreeCache) on the cache tree structure. How eviction policies work

and how the cache interacts with persistent storage. Important knowledge for

anyone looking to provide highly scalable and responsive systems with high

availability and full transactional support.

 10. EJB Clustering. In this module we cover the current clustering implementation

for EJB implementations, from replicated JNDI tree implementation to load

balancing and failover features of EJBs. We will show you how we take

advantage of the JBoss smart proxies with pluggable load balancing

implementations and how the proxies are dynamically updated with cluster

topology changes.

 11. Fine Tuning JBoss Application Server. Learn the tricks and skills to fine tune

your JBoss application server for production usage. Find out what to do to

minimize serialization, how to increase your server’s concurrency and throughput

with correct locking policies and how to make an effective use of caching for your

EJB’s. We cover the differences between default pessimistic, instance per

transaction and optimistic concurrency. Cache invalidation strategies and commit

options, fine tuning the virtual machine and read-mostly clustering strategies.

Critical knowledge before going to production with your JBoss application server!

 12. Security in JBoss. Learn how to secure your EJB applications with JBoss. This

module explains the nuts and bolts of JBoss’ security implementation, how you

can configure it to integrate with your existing security infrastructure and how to

extend it to do your own custom security implementations. We will discuss how to

use JAAS to integrate with existing databases and LDAP authentication systems,

how to do per-instance security based on EJB state and invocation context, and

how the security context propagates between components in the application

server.

 13. JBossMQ. This module covers our messaging implementation. We will see an

architecture overview into JBossMQ implementation, the different parts of the

messaging infrastructure and how they interact with each other. We will show

you how the message passes through the system, what the different invocation

layers are, how to create your own server side interceptors for messaging, how

to secure your JMS destinations and how to configure your message persistence

and cache. Learn all about the high availability features of JBoss messaging

implementation and how to use and configure it. For anyone using messaging in

their application, this module provides all the essentials.
