Amazon.com Review
Q&A with Martin Kalin, author of "Java Web Services: Up and Running, 2nd Edition"

Q. Why is your second edition of “Java Web Services: Up and Running” important for people to read right now?

A. Web services and their clients are an increasingly prominent aspect of the web. For example, social networking sites such as Facebook, Instagram, Twitter, and Tumblr together with e-commerce sites such as Amazon and eBay make available, through web services, the same data and functionality available through traditional websites. Indeed, it is rare nowadays to develop a website that is not paired with a web service.

Q. What will readers walk away with after reading "Java Web Services: Up and Running?"

A. The main informational points can be summarized as follows:

  • Web services are a way to deliver data and functionality using existing technologies and infrastructures already in place. Such services represent a low-fuss approach to web-based applications.
  • Web services represent a straightforward way to automate web-based tasks (for instance, ordering supplies from a vendor) and to integrate legacy software systems (for instance, a legacy COBOL system) with more modern systems.
  • Web services are platform and language neutral: a web service written in a particular language and published on a particular platform is accessible to clients written in many other languages and executing on basically any computing device, from an industrial-strength server to a cell phone.
  • Java provides complete coverage of web services, on the service and the client side; Java provides such coverage with rich options for programming and publishing web services.
  • Web services come in two major flavors, REST-style and SOAP-based, and Java has excellent support for each flavor—on the service and the client side.

The book emphasizes code, on both the service and the client side. Accordingly, there are various full-code examples, on the service side, for all of popular Java APIs for doing REST-style and SOAP-based web services: HttpServlet, JAX-RS, Restlet, JAX-WS. There are also extensive examples on the client side, including clients against popular real-world services such as those from Amazon and Twitter. The book includes a full chapter on wire-level and users/roles security.

Q. What's the most exciting and important thing happening in this Java web services?

A. The distinction between traditional HTML-based websites and web services continues to blur. For one thing, modern websites typically contain JavaScript (in one dialect or another) embedded within the HTML; and embedded JavaScript is increasingly used to write clients against web services.

Q. Can you give us a few tips when getting started with Java Web Services?

A. 1. Traditional programming skills used to create Java-based websites using the JSP/ HttpServlet APIs transfer nicely to REST-style web services. The publication of a Java-based web service is essentially the same as that for a Java-based website (for example, a web server such as Tomcat or Jetty can be used for either).

2. Despite the growing popularity of REST-style services, SOAP-based services delivered over HTTP/HTTPS remain a programmer-friendly variant of REST-style services; and SOAP-based clients are typically easier to write than REST-style ones.

3. Programming a web service and then publishing it are nicely separated concerns: In general, how the service is programmed (for instance, the APIs used) has little or no impact on how the service is published (for instance, with a command-line publisher, a commercial-grade web server such as Tomcat, or a full-blown Java Application Server such as GlassFish or JBoss).

4. jQuery and other JavaScript dialects make it increasingly easy to embed web-service clients within HTML pages.

5. Securing a web service is essentially the same as securing a web site.

A code centric tour of Java Web Service APIs
By Ammy_Evaluator
The book describes itself as "a code centric tour through the APIs and implementation technologies that support web services under Java."

Key words being "code centric" and "tour".

What you get:
##########

++ Lots of examples using key Java web service technologies.
....Service development examples using plain vanilla servlets, REST with JAX-RS/Restlets/JAX-WS, and SOAP with JAX-WS.
....Service deployment examples using a servlet container or an Endpoint publisher.
....Client development examples using plain Java (URLConnection), WADL generated classes, etc.
....Tooling such as xjc, wsimport, schemagen, wadl2java, etc.

However, here's what is missed:
######################

-- Not enough detail on supporting technologies such as JAXB, XML parsing, XML Schemas, etc.
-- Focuses heavily on Amazon's E-commerce API, which is too complex to make for readable examples in a short book. (This complexity is acknowledged in the section on async clients.)
-- The focus is on implementation, not design. So, no discussion of REST principles, good API design, etc.

Note that a significant complaint with the first edition was poorly written code examples. While I have not executed the code, all the snippets looked reasonable to me. However, the ZIP archives I downloaded from the O'Reilly site (points to github.com/mkalin/jwsur2) could not be opened using WinZip 12.

ConclusioN:
########

The emphasis of this book is on coding services and clients. As a result, it avoids high level concepts, best practices, and provides only summary level discussions of other adjacent APIs.

This single minded focus may not be for everyone. However, I found it rather refreshing as there are enough high brow, but useless, books out there.

Happy SOA!

Good book only if you want to see the variety of possible WS implementatons
By Florin Vasile
Instead of concentrating on a way to build efficient WS with standard Java Technologies this book tries to touch every possible way to create a web service with standard and non-standard technologies.

I would recommend concentrating more on Java EE and ways to build highly efficient web services with the standard technologies instead of exploring Restlet.

Just enough information to get you up and running
By David C.
I have been a Java programmer for many years. Right now I have a project that requires me to implement a Java web service. I have a very minimal understanding on both RESTful and SOAP-based web services prior reading this book so this book is really my first book that I used to help me to gain more understanding on Java web services.

Here's my thoughts on this book.

- This book assumes you know some Java and object oriented programming since various Java technologies that enables RESTful web services and SOAP-based services use various OO techniques.

- If you have some understanding (even a little) on XML, JSON, HTTP(S), RESTful and SOAP then you will find this book much easier to understand and enjoyable.

- I think this book is written at a high level to get you up and running quickly with Java Web Services, it covers just enough so you can start working therefore chances are after reading this book you will still need to find some additional materials to dive into the ins and outs of whatever Java Web Service type you plan to implement. Since this book already provided you with the fundamental background so now you just need to read upon specific topics that you need.

- The example code does work but requires very minor modification. For example the shipped build.xml needs to modify to include the location of your $TOMCAT_HOME. No biggie, a very easy modification. Also I found it very easy to deploy the code in a Linux environment. I am not sure if it would be easy if you are in a Windows environment.

In summary this book met my expectation. My expectation is simply to get myself as quickly as possible to get up to speed with Java Web Services. It provided enough information for me to pick what type of Java web services (RESTful or SOAP-based) I want to implement for my project.
