Amazon.com Review

Java 1.1 Networking & Communications serves as an excellent text for beginning and intermediate programmers who want to find out how one Java entity (a thread, a class, whatever) communicates with another. By working through the excellent code samples here, which do such things as implement the finger protocol, readers become familiar with the essentials of Java communications.

This book opens with an in-depth discussion of streams, which are essential to all Java communication--among a single program's threads as well as among separate programs. You get information on the logic behind streams, the various ways to implement streams in Java, and some example uses for streams. The author then moves on to the Internet, detailing the URL-related classes, especially java.net.URL and java.netURLConnection. He then covers threads, sockets, and packets.

Unfortunately, there's no coverage of Remote Method Invocation (RMI), which would have made this book more complete. Still, the information that's here--and there's a lot of it--is excellent, and this book, which comes with a CD-ROM, is an excellent introduction to Java's networking capabilities.

From the Back Cover

Build communicating applications with Java.
Take advantage of Java's tremendous potential for communications with Java Networking and Communications, the first complete, practical guide to creating network and communications applications in Java.
Discover how to implement all the essential components of a networked application by using Java's powerful stream, socket, and thread libraries.
Master important new JDK 1.1 networking features such as character streams, object streams, and multicast sockets. Then, step-by-step, construct your own complete communications and networking applications:


*A Web server

*An Internet chat client

*A terminal emulator

With the help of extensive sample code and illustrations, learn the Java programming techniques most relevant to communications, including:


*Blasting data through your application using Java's powerful stream classes

*Adding multiple threads to your application to make it more responsive to the user

*Using Java's HttpURLConnection class to build HTTP-based applications

*Creating TCP network clients and servers with sockets

*Native code library linking for Win32, MacOS, and Solaris

*Using Java's datagram classes for fast and efficient network applications

*Linking with existing legacy code under Win32, MacOS, and Solaris

Through all phases of software development, Java Networking and Communications assists you in building the best possible communications and networking code. It includes advice on code organization, prototyping, debugging, and optimization.
In addition the book provides an extensive set of communications code examples you'll find nowhere else such as:


*An interface to Win32 and Solaris serial communications

*An interface to the MacOS CommToolbox, including an AppleTalk ADSP interface

*Java code for collecting Global Positioning System (GPS) receiver data

*A datagram client that parses Domain Name Service (DNS) data, and a custom datagram protocol

*An autonomous Web content downloader "drone"

4.0 out of 5 stars DLL for serial communications is missing from the CD, January 28, 1998

By A Customer

This review is from: Java Networking and Communications (SunSoft Press Java) (Paperback)

I purchased this book because it specifically offered serial communications using Java, including the required DLL for Windows use. Unfortunately, the DLL is not on the CD. I have sent mail to the author. He states that "In the coming weeks if I have time I will rebuild the DLL and place the binary up on the website". That was in late November. Still, there is no DLL.
I should note that, while the CD is VERY poorly organised (no install, backup files everywhere, multiple directories to copy for the .class files to be usefull, etc.) the book reads well.

3.0 out of 5 stars Well written but relies on a poorly made CDROM., September 22, 1998

By A Customer

This review is from: Java Networking and Communications (SunSoft Press Java) (Paperback)

The explanations are well written and easy enough to understand, but the downfall of this book is its reliance on an EXTREMELY poor CDROM. The java class heirarchy isn't present on the CDROM, making it a very tedious job to copy all of the example files on to your hard disk so that they will work correctly with java's packaging characteristics. In fact, there are even errors present in the code on the CDROM, creating another cumbersome task of finding the updated source code on the web site, if it's there, and then copying that code onto your....... You get the point.

The actual book covers helpful topics in an interesting and fairly easy to understand way as long as you're familiar with Java programming and the Java API. On the Other hand, many of the code examples rely on the reader to examine and execute the code on the CDROM, which is sub-par at best.

This is not a bad book, but don't let the fact that it comes with a CDROM including examples and the jdk1.1.3 on it throw you. Besides, you could be downloading a higher version of the jdk right now for free...
