JBoss for Advanced J2EE Developers

course content details

	JBoss Architecture Overview

OverviewThe 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.

	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.

	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.

	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.

	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.

	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. We will also discuss JGroups group communication protocol architecture and configuration at high-level.

	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.

	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.
