Excerpts
About this Book Target Audience This book targets all mobile software developers and business decision makers. It focuses on end-to-end architectural patterns, best practices, key innovations, and real-world design approaches. For different readers, this book offers different benefits: Managers and entrepreneurs: This book is a comprehensive guide to mobile enterprise applications and the Java 2 Micro Edition (J2ME). It covers the capabilities, limitations, common best practices, and commercial solutions of the state-of-the-art mobile Java technologies. It helps you decide which mobile Java profile and products are the best for your business. Experienced mobile developers: This book skips the basic MIDP API tutorial materials and goes straight to the more advanced and more useful topics. It uses several complete sample applications to illustrate common architectural patterns and coding best practices in mobile enterprise applications. For developers who are looking for specific solutions (e.g., messaging, database, XML, and security), the technical discussions on leading third-party J2ME tools and libraries will prove useful. Those real-world innovations also serve as prime examples of how you should design and implement your own solutions for similar tasks. Experienced Java developers: For experienced Java enterprise developers (J2EE developers), the move to mobility is about leveraging existing skills. This book walks through familiar design patterns and best practices and shows developers how to apply them in mobile applications. Lightweight mobile versions of enterprise Java APIs (such as JDBC, Java servlet, JMS, and Java Cryptography Extension) are discussed. Those are excellent examples of how to scale down enterprise solutions for mobility while still preserving core functionalities. With a few notes on mobile-specific issues, it is the fastest path to add mobility to existing enterprise infrastructure. Prerequisites To fully understand the technical content in this book, the readers should be familiar with the basic Java 2 Micro Edition, Mobile Information Device Profile (J2ME/MIDP) APIs and development tools. A quick MIDP programming guide is provided in Appendix A. To run the end-to-end sample applications, you will need to deploy the serverside components to your own Java application server and run the clientside components on the desktop emulator or real devices. Please refer to the product manuals of your tools for step-by-step instructions. Although serverside Java is not the focus of this book, familiarity with basic Java 2 Enterprise Edition (J2EE) concepts such as servlets, Java DataBase Connectivity (JDBC), Java Messaging Service (JMS), Java XML processing, and Enterprise JavaBean (EJB), will help you understand various topics in this book. Contents This book is divided into six parts: Part I is the introductory material for mobile commerce, mobile enterprise applications, and J2ME. It covers the overall architecture, current status, and future roadmaps of J2ME. Part II is the heart of this book. It presents several example applications to illustrate the smart client mobile application paradigm, common architectural patterns, and best practices. It covers how to run container-managed applications (e.g., servlets) on PDA devices. It also presents a useful advanced HTTP client library for J2ME clients. Part III is about mobile messaging. In the mobile world, messaging clients are easy to use and fit into the mobile lifestyle. In the enterprise world, messaging is the best way to build loosely coupled applications that have guaranteed quality-of-service (QoS). This part of this book seeks to combine the best of the two worlds. It covers email and SMS-based end-to-end applications as well enterprise mobile messaging servers. Part IV dis
