Featured Customer Reviews  Totally over-rated and out of date,
March 03, 2004The book is REALLY HARD TO READ, we are talking as dry as the sphinx's arm pit. The CD rom that comes with it contains the examples, however these are a mish-mash of VB6 and some .Net neither of which run easily. The .Net versions require updating in Visual Studio and can have some odd results. Some examples are even written with the server component in VB6 and the client in .Net - confusing to say the least. If you want to learn how to practically implement a Web Service using VB then you should NOT look at this book. Most of the first 4 chapters are all about XML schemas and what they mean - with no "Real World" examples of how to create them in VB just the code of the schemas already created. And another thing there is a large chunk of information about a "Real World" authentication and encryption implementation, however and I quote "I recommend that you use off-the shelf security implementations" - The author wouldn't even use this code! Microsoft has a Web services extension designed for authentication which the author doesn't mention anywhere. Very disappointment to have spent good dollars on this book. I will be trying desperately to get my money back from Amazon.  Excellent book,
August 18, 2003Real World XML Web Services is an AWESOME BOOK!!!,
August 16, 2003 Web Services. I can't believe there is anyone left alive in the technology sector that hasn't heard these two words. Everywhere you look there are articles, books, and web sites that talk about this technology. Do a book search for "Web Services" on amazon.com and you will be quite amazed how many Web Services books there are. With so many available picking one buy may seem overwhelming. The good news is it just got a little easier to do. Real World XML Web Services is an absolute "must have" for anyone who wants to learn more about XML Web Services. Even if you are not a VB/VB.net developer you will find great value in this book. It goes into extensive detail, and will surely teach even more savvy Web Services folks a thing or two. Because of the books detail level, I don't think that it is a first-read on the subject though. I think that someone who really doesn't know much about Web Services will be drowned in the detail (which is incredible). A person can get more out of this book by doing some tutorials, and experimenting with Web Services first. Then, after having a good base of understanding is when this book should be cracked. Summary Chapter 1. Introduction to Web Services.
This is a brief intro chapter that gives some history and background info about Web Services. Some of the overview consists of typical Web Service architecture, and when to use (and NOT to use) Web Services. Chapter 2. XSD: The Web Services Type System.
Great chapter. Goes into the concepts of XSD. Topics include the XSD Type System, XSD and XML namespaces, authoring XSD Schemas, and a ton of information about XML Serialization.
.
Chapter 3. SOAP: Invoking Web Services.
This chapter covers what SOAP is, SOAP architecture, SOAP message formats, RPC with SOAP, and also covers error handling. Chapter 4. Describing Web Services.
A chapter all about the Web Services Description Language (WSDL), which is the language used to describe Web Service interfaces. I liked this chapter a lot because Yasser does a great job of really illustrating and explaining it well. Clear, easy to follow examples are used to drive concepts home. Chapter 5. The Microsoft SOAP Toolkit.
As you might have guessed, this chapter is all about using the Microsoft SOAP Toolkit to invoke and expose Web Services. If you would like to know more about the toolkit you will like this chapter. Exposing and invoking Web Services via the high and low-level API's is covered, as well as using header handlers to invoke and expose. Chapter 6. .NET Web Services.
This chapter discusses creating .Net Web Services with Visual Studio .Net, as well as customizing the WSDL of the Web Service to meet your needs. Chapter 7. SOAP Header and Fault.
All about SOAP headers and SOAP Fault. There is some great information about communicating errors in a common way so that any platform can get to it. Chapter 8. Interface-Based Web Service Development. Explains about Interfaces and the .Net Web Services world. Defining interfaces, implementing multiple interfaces, and programming against interfaces are some of the topics covered. Chapter 9. Handling Data IN.NET Web Services.
This is a chapter that shows how to take data from many different types of sources and be able to manipulate it using XML Schemas, ADO.Net, and the XML Framework. Typed Datasets are also covered. Chapter 10. Reusable Infrastructure with Soap Extensions.
This chapter teaches how to built a flexible and reusable infrastructure using SOAP extensions. Chapter 11. UDDI: A Web Service.
This huge chapter pretty much tells us everything about UDDI that you could want to know. The chapter starts with an explanation of what it is and what it is made of. Then the chapter goes into different usage scenarios and various other UDDI topics. Programming, querying, and publishing Web Services with UDDI are just some of the other topics covered. This is an excellent chapter. Chapter 12. Other SOAP Toolkits.
This chapter talks about Web Services Interop . Different clients are discussed including JAVA clients, VB 6 clients, and NET clients. Chapter 13. A Web Service Walkthrough.
This chapter wraps up the book by walking the reader through building a Web Service. This is a great way to end the book as it ties together all the things that were discussed. Appendix A: Data Type Mappings
Appendix B: .NET Web Services Tips and Tricks. Two good appendixes that give us more information, as well as tips and tricks.
I give this book a 10 out of 10. Yasser did a fantastic job on it. Again, although I do not think this is a "first read" book on Web Services, I believe it is a "must have" Web Services book. Any developer that works with, or wants to work with Web Services will find it valuable. Real World XML Web Services ROCKS!!!!!!!!,

May 24, 2003 This is a good book but suffers from bad writing style.
The author uses many "and/or" clauses one is forced to
pause to understand what he is really attempting to say.
He also asks questions in the middle of an explanation. For example on page 38 section 2.4.7 he says:
"An element doesn't need to have content;it may be empty. An empty element is an element that has no text content and no child elements. Would such an element be of complex or simple type? it depends; if the element has attributes it is of complex type. Note that attributes are not considered part of an element's content, therefore whether or not an element has attributes has nothing to do with whether or not the element is empty: an empty element may nor may not have attributes." Does the author have to use 108+ words to tell us that an empty element is just that. Empty!
For example read his last sentence and see whether you understand what he is talking about. He could simply state the last part: "an empty element may or may not have attributes" for us to understand. Where "therefore whether or not an element has attributes has nothing to do with whether or not the element is empty:" came from I have no idea! I am not sure whether the author is affected by English as a second language or whether he bothered to understand what he was writing. In an attempt to simplify the content he ends up in verbosity and ruins what would have been a good book. Overall if one can put up with long winded paragraphs it is a good book.
