Every J2EE application is unique and it is difficult, if not impossible, to extrapolate performance results from one application to another
So, in this book we provide a load generating tool and a simple, adaptable methodology that will help you obtain detailed performance data for your own applications. We show how to performance test complete J2EE applications, and also how to explore key performance issues surrounding the most popular J2EE APIs. In this way, we elucidate the methodology, and set a general level of expectations with regard to J2EE performance. Building on this foundation, developers can continue to explore the performance issues that directly affect them and can use their own test data to make informed business decisions about the design and development of their applications. Assuming a good knowledge of the J2EE technologies, the book is aimed at: • Java architects and high-end developers responsible for overall design decisions for J2EE-based applications • Developers responsible for performance tuning and benchmarking • System administrators responsible for the day-to-day running of the applications The performance tests in this book are carried out using BEA WebLogic Server, but are generally applicable to any J2EE application server. Written by recognised experts in their field who work with J2EE developers on a day-to-day basis, this book provides a detailed reference that can be used to design, evaluate and understand the performance of enterprise J2EE applications. The book has been developed and honed to meet the precise requirements of experienced Java architects, developers or administrators, responsible for building or maintaining such applications. Author Biography: Peter Zadrozny is the Chief Technologist for BEA Systems responsible for Europe, Middle East and Africa. Peter is constantly travelling his region, meeting with prospects and customers using BEA WebLogic Server and helping them to design solutions to their business challenges. Peter also spends a fair amount of time helping BEA customers fine tune and improve the performance of their WebLogic Server based applications. Peter is the co-author of 'Java 2 Enterprise Edition with BEA WebLogic Server' (Wrox Press, 1861002998). Phil Aston is a senior consultant with the Professional Services organisation of BEA Systems in the UK. In this capacity, Phil assists BEA customers with the detailed architecture design, proofs of concept and implementation of applications using J2EE technology. In his spare time Phil has taken the role of lead developer responsible for 'The Grinder', a Java load-testing tool.
