5.0 out of 5 stars A great survey of mobile technologies, January 30, 2004
By 
Dan (Boulder CO) - See all my reviews
This review is from: Enterprise J2ME: Developing Mobile Java Applications (Paperback)
I go to Java Users Groups (yes, I'm struggling to get in touch with my inner geek) once every two or three months. Sometimes there's an engaging speaker, but most of the time the fellow up front looks like he's just swallowed a hot pepper, speaks like he has a permanent stutter, and answers questions like I'm speaking Greek. (I'm not making fun; I had a hard time when I was in front of a JUG too.) Regardless of the quality of the speaker, I gain something just by watching the presentation--he points out interesting technologies and usually has a list of resources at the end that I can use for further research.

I think Michael Yuan would be a great speaker at a JUG, as he seems to have a masterful understanding of Java 2 Platform, Micro Edition (J2ME). However, the true value of his book, Enterprise J2ME, was in its introduction of new ideas and concepts, and the extensive resource listings. This book is a survey of the current state of the art in mobile java technology. Whatever... Read more

4.0 out of 5 stars Emphasis of J2ME is shifting to the server, November 25, 2003
By 
W Boudville (Terra, Sol 3) - See all my reviews
(VINE VOICE)    (TOP 1000 REVIEWER)    (HALL OF FAME REVIEWER)    (REAL NAME)   
This review is from: Enterprise J2ME: Developing Mobile Java Applications (Paperback)
The substance of this book bodes well for the future of J2ME. As you may known, there have been several books on J2ME published in the last year. Like "Java Development on PDAs" by Wilding-McBride. For the most part, these have been aimed at someone completely new to J2ME development. They have tended to focus on the client side, because this is more tangible and easier to explain.

Here Yuan shifts the focus to the server side. He does have screen shots of some client UIs and related code. But the bulk of the discussion moves to server related issues, like how can you sync to a database, or how to send SMS messages in a network. You can consider the book to be focused on connectivity. Not at the lowest level of network connections, but at a higher conceptual level of hooking to existing applications.

In part, this is because UI capabilities are much more limited compared to those on a full Java desktop or even a laptop. But it is mostly because the bigger value is in... Read more

5.0 out of 5 stars The coverage of the book, October 24, 2004
By 
Juntao Yuan (Austin, TX United States) - See all my reviews
(REAL NAME)   
This review is from: Enterprise J2ME: Developing Mobile Java Applications (Paperback)
I just feel compelled to respond to Mr. Faria's negative and factually inaccurate comments about the content of the book -- especially the database chapter.

First of all, the book has 4 chapters on mobile databases. There are 65 pages in them. Only 7 pages cover the JDBC introduction and they are focused on the J2ME version of JDBC. The rest 58 pages cover the data access and synchronization strategies and APIs for leading mobile databases. Those APIs are often NOT JDBC-compatible. There are also several example mobile database applications as well as system design suggestions.

Can you find most of the information by searching google and reading product manuals? Yes, you can, if you have a lot of time. The value of the book is to save the reader time.

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 discusses mobile databases that are core to occasionally connected and synchronization-based applications. This part covers commercial and open source innovations for mobile databases, synchronization engines, and legacy database connectivity. Two sample database applications from PointBase are presented.
  • Part V covers how to integrate mobile clients into the enterprise Web services infrastructure. It discusses existing and emerging J2ME XML and SOAP toolkits, specifications and showcases several complete sample applications.
  • Part VI is all you need to know about J2ME mobile security solutions. It goes way beyond the simple connection-based end-to-end solutions such as the HTTPS. This part covers open source and commercial cryptography toolkits for J2ME. Due to the complexity of cryptography APIs, API tutorials for each important toolkit are provided.
  • There are two appendices to this book. One of them uses a simple end-to-end MIDP application to illustrate the whole development and deployment cycle. The other appendix introduces the IBM WebSphere Studio Device Developer IDE and provides undocumented instructions on how to install IBM J2ME runtimes on PocketPC devices.

Code Examples

This book uses complete example applications to demonstrate design patterns, best practices, and important API usages. Since this book discusses a wide range of technologies, innovations, and application scenarios, it is impractical to cover everything within a monolithic example. Instead, I decided to develop several small to midsize samples, each focusing on a particular topic. This approach allows the readers to partition the learning task and read one part of this book at a time.

The source code is presented in easy-to-digest segments that are relevant to the discussion text. Nonessential parts of the code (e.g., exception handling, importing packages) are often deliberately omitted from the listings for clarity. Hence, the printed listings are suffcient for understanding the ideas but are not directly runnable code.

  • iFeedBack : The grand prize winner of the NexTel/Motorola/Sun wireless application contest in 2002 (Chapter 3).
  • Echo : A GUI client and a service running in an OSGi clientside container (Chapter 4).
  • Pizza Order : An example included in the IBM Service Management Framework download. It demonstrates how to build smart clients with HTTP front ends (Chapter 4).
  • Smart Ticket : The Sun Wireless Blueprints application v2.0 early release code (Chapter 5).
  • HttpClient : The code for the advanced HTTP library we develop in this section (Chapter 6).
  • Mail : An MIDP email client based on the Mail4ME v1.0 library (Chapter 8).
  • WMATester : A simple messaging application that illustrates the use of Wireless Messaging API v1.0 (Chapter 9).
  • ContactManager : A mobile address book based on the PointBase v4.5 library (Chapter 11).
  • ContactManagerSync : A synchronized mobile address book based on the PointBase v4.5 library (Chapter 13).
  • AmazonExample : An kXML client for AmazonWeb services using both kDOM and XmlPull APIs (Chapter 15).
  • PeekAndPick : A RSS reader for mobile phones developed by Jonathan Knudsen (Chapter 15).
  • Google : A simple client for the Google Web services API. Both kSOAP v1.2 and v2.0 versions are available (Chapter 16).
  • SmartPhrases : An integrated Google search and online dictionary application (Chapter 16).
  • MapPoint AxisFacade : An Apache Axis facade for MapPoint v3.0 Web services (Chapter 18).
  • MapPoint AxisClient : Personal Profile and MIDP clients for the Map-Point facade (Chapter 18).
  • MobileSecurity : A collection of small applications that demonstrate the correct usage of cryptography APIs (Chapter 20).
  • SimpleDemo : A simple MIDP application to illustrate key concepts and APIs in MIDP programming (Appendix A).

Commercial Products

This book covers and compares more than 30 toolkits and libraries from more than a dozen third-party vendors. The descriptions and API usage examples of those products are intended to give the readers a solid technical ground to make informed comparisons and decisions. They also serve as realworld examples for API and tool designs. However, they do not substitute for the formal product documentation from the vendor. I strongly encourage interested readers to obtain the latest evaluation package and documentation from the vendor to investigate further.

Related Publications

Some of the materials used in this book are loosely based on articles I published previously on several online magazines.

  • The Sun Smart Ticket blueprint discussed in Chapter 5 is also covered in “End-to-End J2ME Application Development by Example,” published on the Sun Wireless Java Web site in June 2003.
  • The first half of Chapter 9 is also covered by “Mobile P2P messaging, Part 1,” published on IBM developerWorks in December 2002.
  • Examples in Part IV are adapted from “High-availability mobile applications,” published on JavaWorld in June 2003.
  • Chapter 16 is based on “Access Web services from wireless devices,” published on JavaWorld in August 2002.
  • The example in Chapter 18 is adapted from “Let the mobile games begin, Part 2,” published on JavaWorld in May 2003.
  • Part VI is loosely based on “Data security in mobile Java applications,” published on JavaWorld in December 2002.

Production Notes

This book is produced by the Latex typesetting system on a 1GHz Apple PowerBook running Mac OS X—the best consumer operating system ever produced. Microsoft Word is used for collaborative editing and reviewing. The figures are made with Microsoft Visio, OmniGra2e, GIMP, and the ImageMagick utilities.

The example applications are developed using a variety of development tools, including VI, JEdit, IntelliJ IDEA, and the WebSphere Studio Device Developer IDE. Apache Ant is used to build the applications. Mobile clients are tested on many vendor SDKs, including those from Sun Microsystems (the J2ME Wireless ToolKit), IBM (the WebSphere Micro Environment), Nokia, and Motorola. Real device testing was conducted on Motorola i95cl, Nokia 7210, Nokia 6800, and PocketPC Phone devices.
