The JBoss Application Server is a Java EE-certified platform for developing and deploying Java Enterprise applications. JBoss Application Server provides the full range of J2EE 1.5 features as well as extended Enterprise services including clustering, caching, and persistence. This book will show Java EE developers how to develop their applications using the JBoss Application Server. It covers topics such as:
Setting up a development environment
Customization
Java EE programming modules
Clustering
Security
All these features will be explored by developing sample and intuitive applications built using the friendly interface of Eclipse and JBoss Tools.
Chapter 1: Installing Core Components covers the installation of the key components that will be needed throughout the rest of the book. The installation process will be completed by using intuitive wizards that will lead even inexperienced users through it.
Chapter 2: What's New in JBoss AS 5.0 introduces the reader to the most significant changes brought by release 5.0 of the application server. The new server directory tree is analyzed in detail and possible variants in the server configuration are discussed in the latter part of this chapter.
Chapter 3: Customizing JBoss Services discusses the core configuration of the application server. The highlights of it include an introduction to JBoss AS monitoring services, the inner details about JBoss thread pool, how to configure logging services, and a detailed description of the transaction and Datasource service.
Chapter 4: Developing EJB 3 Session Bean introduces the reader to some concrete Java EE programming examples developed on JBoss AS 5. The focus of this chapter is on EJB 3 session Beans, including a section about their configuration for optimal results.
Chapter 5: Developing JPA Entities covers the development of an example based on the Java Persistence API (JPA). Here, we introduce an enterprise application named the Appstore, which will be a central theme of this book.
Chapter 6: Creating a Web Application is about developing and configuring web applications on JBoss AS 5.0 using the JSF cutting-edge technology. In the first part of this chapter we will enhance the Appstore Enterpirse application by adding a web layer to it. In the latter part, we explain in detail how to properly configure JBoss Web Server.
Chapter 7: Developing Applications with JBoss Messaging Service discusses JBoss Messaging provider by giving a short introduction to the new messaging system. The chapter then helps us set up some proof of concept programming examples.
Chapter 8: Developing Applications with JBoss and Hibernate covers the de facto standard object relational mapping tool, Hibernate, showing how to quickly set up a Hibernate project using the facilities provided by the JBoss tools interface.
Chapter 9: Managing JBoss AS covers the Java Management Extension (JMX), which still plays a vital role in the application server infrastructure. The chapter includes many examples that show how to write traditional MBeans services and the new POJO Services.
Chapter 10: Developing Applications with JBoss Web Services focuses on the JBoss Web Service implementation, JBossWS, showing how to create, deploy, and test Web Services on JBoss AS along with some advanced concepts such as Handler chains and SOAP debugging.
Chapter 11: Clustering JBoss AS covers the facts about JBoss AS clustering configuration, moving from cluster basics to detailed configuration of the individual services of the application server.
Chapter 12: Developing a Clustered Application continues the journey in the clustering arena by adding some concrete examples based on the abstract concepts covered in the earlier chapter.
Chapter 13: JBoss AS Security provides a systematic guide to JBoss security framework and the cryptographic interfaces available in the Java EE framework. This supplies the basis for concrete examples, which are delivered in the next chapter.
Chapter 14: Securing JBoss AS Applications continues the in-depth exploration of the JBoss security framework, adding concrete programming examples applied on the EJB and Web Services technologies.
If you are a Java architect or developer who wants to get the most out of the latest release of the JBoss application server or a JBoss administrator who wants a clear and simple reference for JBoss services, this book is for you. You are not expected to have accumulated experience on the application server though you must know the basic concepts of Java EE.
In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.
Code words in text are shown as follows: "Since release 5.1.0 of the application server, the admin console is bundled as a web application in the deploy folder of JBoss AS."
A block of code will be set as follows:
<mbean code="org.jboss.util.threadpool.BasicThreadPool"
name="jboss.system:service=ThreadPool">
<attribute name="Name">JBoss System Threads</attribute>
<attribute name="ThreadGroupName">System Threads</attribute>
<attribute name="KeepAliveTime">60000</attribute>
<attribute name="MaximumPoolSize">10</attribute>When we wish to draw your attention to a particular part of a code block, the relevant lines or items will be shown in bold sometimes with numbers in square brackets referring to notes in the text:
<attribute name="Log4jQuietMode">true</attribute> <attribute name="RefreshPeriod">60</attribute> [1] <attribute name="DefaultJBossServerLogThreshold">DEBUG</attribute> </mbean>
Any command-line input or output is written as follows:
twiddle -s localhost invoke "jboss.system:type=ServerInfo" listThreadCpuUtilization > threadCpu.txt
New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in our text like this: "In the left frame expand the Resources | Datasources leaf and choose the suitable transaction option."
