Amazon.co.uk Review
For any developer writing mobile applications on the Java platform, from smart cards to pagers to PDAs, Professional Java Mobile Programming provides both a "big picture" perspective on Java running on all these platforms, as well as some practical detail on the APIs and design strategies you'll need to get started.
This book's principal strength is probably its complete coverage of mobile Java's possibilities. From tiny smart cards, to Java-aware phones, to pagers and even full-fledged PDAs, the authors cover the dizzying array of acronyms involved in the Java 2 Micro Edition (J2ME). The actual source code here concentrates on two flavours (called profiles) of J2ME: the MIDP (for PDAs) and the CLDC (for pagers). To this end, this text covers both high-level controls available on the MIDP platform, and then lower-level graphical calls. They provide a case study for a contact manager then port it to the more restricted form factor of the CLDC standard.
Coverage of smart card programming will help get you started there. With just a few bytes of memory, programming smart cards requires a very different mindset, and this text shows you how to work with these devices. Coverage of additional abilities in mobile Java from the Java Message Service (JMS) and telephony APIs rounds out the text. The authors anchor their sometimes wide-ranging discussion with some larger case studies including a Towers of Hanoi simulation and a mobile application that uses global positioning information.
Later samples integrate mobile applications into the larger J2EE platform on the server-side. The code here mixes in technologies such as servlets, EJBs, XML and XSLT with mobile user interfaces. A discussion of the software design process geared toward mobile development closes out this book. Useful reference sections compare the MIDP and CLDC APIs, as well as listing all available classes and methods in each.
Though this text at times adopts a somewhat scattershot approach in its organisation, its overall coverage of the rich possibilities of today's different mobile Java standards will help make it a useful resource for understanding what Java has to offer when it comes to mobile computing. --Richard Dragan
Book Description
J2ME is an exciting set of technologies that provide integration of Java with wireless devices, and bring Java back to its design roots. Wireless device types, operating systems, and networks will proliferate, but Java provides a unifying programming platform for these devices.
The potential of a flexible and secure run-time environment on these new devices is immense. Mobile code, context or location-sensitive web-based services, and inter-device communication are all possible between differing devices.
The recognition that 'one size doesn't fit all', however, and the resulting introduction of configurations and profiles, is confusing. Java is still 'write once, test everywhere,' in developers' minds. This book answers in one volume the need for a detailed examination of the differences and similarities between implementations of J2ME.
Currently, deployable context based services are only possible through WAP. The book covers this exciting new area of providing location-based services.

Don't expect too much on this book, 17 Aug 2001
By Leo Chan Wing Ko - Published on Amazon.com
This review is from: Professional Java Mobile Programming (Programmer to programmer) (Paperback)
If you are a developer and eager to find resource on Java Mobile development, this book must disappoint you. This book just give you a general java mobile concept. May be this technology is too green so that all topics are not in depth to discuss with very limited examples. The worse of this book is some examples just show the source code only with no any demonstration of the program running or even the complied result and that made people hard to understand what the source code mean.
If you see the content that this book cover MIDP for Palm. Don't believe this, this book is only cover the early stage of java KVM in Palm but not included the current Sun MIDP for Palm OS

Great coverage and good case studies, 8 Dec 2002
By "cogito512" - Published on Amazon.com
This review is from: Professional Java Mobile Programming (Programmer to programmer) (Paperback)
I found this book very useful for getting to grips with the wide range of technologies available for Java platform on mobile devices. It's strong point is the breadth of subjects covered and not the depth. However, if like me, you prefer to get on to a quick start and the get deeper into the subject on a "as needed" basis this book will provide it. It got me up to date and able to continue on my own from the first three chapters.If you are already an experienced J2ME developer then the case studies will show how others have tackled some J2ME problems. If you are a beginner then you will get a complete treatment of the range of technologies.

What a Lousy Book!!!, 2 Jan 2002
By Shih Chia Cheng "Jacob Cheng" - Published on Amazon.com
This review is from: Professional Java Mobile Programming (Programmer to programmer) (Paperback)
This is the worst book I have read so far. There are so many errors in the book! And all descriptions about J2ME are vague. It's really a pity that I spent my money on this useless book.Don't buy this book!!!
Listmania!
