JBoss AS 5 Performance Tuning

Overview of this book

Today's organizations need to deliver faster services to a large set of people and businesses. In order to survive this challenge, enterprises need to optimize the performance of their application server along with its components and hardware. Writing faster applications is no longer just an option for your products; it's an imperative requirement, which you cannot ignore. JBoss AS 5 Performance Tuning will teach you how to deliver fast applications on the JBoss Application Server and Apache Tomcat, giving you a decisive competitive advantage over your competitors. You will learn how to optimize the hardware resources, meeting your application requirements with less expenditure.The performance of Java Enterprise applications is the sum of a set of components including the Java Virtual Machine configuration, the application server configuration (in our case, JBoss AS), the application code itself and ultimately the operating system. This book will show you how to apply the correct tuning methodology and use the tuning tools that will help you to monitor and address any performance issues. By looking more closely at the Java Virtual Machine, you will get a deeper understanding of what the available options are for your applications and how their performance will be affected. You will learn about thread pool tuning, EJB tuning, JMS tuning, Enterprise Java Beans, and the Java Messaging Service. The persistence layer and JBoss Clustering service each have a chapter dedicated to them as they are two of the most crucial elements to configure correctly in order to run a fast application. You will also learn how to tune your web server, enabling you to configure and develop web applications that get the most out of the embedded Tomcat web server.

Tuning web services

The other broad category of web applications includes web services, which is a typical B2B technology. Web services have deeply changed the landscape of B2B services by introducing a common transport protocol for network communication, which before was left to different kinds of adapters and plugins provided by the single application server.

How do web services actually bridge different systems? Web services use XML as the standard for exchanging data across disparate systems. Specifically, the XML content needs to be converted to a format that is readable by the Java application and vice versa. Data binding is the process that describes the conversion of data between its XML and Java representations.

The current standard for designing web services is JAX-WS, which uses Java Architecture for XML Binding (JAXB) to manage all of the data binding tasks. Specifically, JAXB binds Java method signatures and WSDL messages and operations, and allows you to customize the mapping...
