Scope
The scope of the book includes developing Java applications for the Palm and PocketPC PDAs using J2ME and PersonalJava, respectively. Strictly speaking, PersonalJava is part of the Java 2 Standard Edition (J2SE) family rather than J2ME, but it is included in the book's scope because most PocketPCs come with PersonalJava installed. Additionally, as I write, implementations of the J2ME replacement for PersonalJava (the Personal Profile, which we will discuss in subsequent chapters) have not yet arrived for the PocketPC.
Although the applications presented in this book will run on other platforms, such as mobile phones, the specific intent is to focus on applications that run on PDAs and the considerations a PDA developer should keep in mind.
In the book, we will consider the end-to-end solution for integrating a PDA into the enterprise. As such, the book does include some server-side code.
Not included is coverage of other PDAs, such as the Sharp Zaurus. To make the book manageable, I decided to concentrate on the two dominant products in the PDA market. Also not included is coverage of PocketPCs running operating systems other than WindowsCE, such as iPaqs that run Linux.
The book does not cover Java-like languages for PDAs such as Waba, since they are not based on the open Java standard.
