After providing a general introduction to Java, author Austin Sincock explores how to open the typically closed SAP environment to the world of Java. </p> <p>Utilizing SAP's latest Java connector, JCo, Sincock details an end-to-end web application that connects directly to SAP, including the deployment and implementation of both a web server and an external database. He explores communicating with an SAP environment through such Java and J2EE technologies as JavaServer Pages (JSP) and the Java Standard Tag Library, and database connectivity through JDBC. </p> <p>Wherever possible, open source technologies are employed to enable flexible Java connectivity to SAP&emdash;atypical for the SAP environment, in which tools are often proprietary.</p>

From the Inside Flap

The fact that you cracked open a book entitled Enterprise Java for SAP means that you are one of the many developers looking to explore the world of Java development for SAP. So far, for many of you, this exploration has been a frustrating and even fruitless search for any tidbit of information on programming for SAP in Java. If this description sounds familiar, then you may find Enterprise Java for SAP a required read.

This book is specifically targeted at developers who are fluent in SAP’s programming language, ABAP, and are looking to learn the Java language. Although targeted at the less experienced Java developer, this book is a great resource for more experienced programmers who need to build applications with SAP’s Java connector (JCo).

5.0 out of 5 stars From the author..., April 5, 2005

By	Austin Sincock (Virginia) - See all my reviews (REAL NAME)

I am the author of Enterprise Java for SAP and would like to clarify a few points about the text. I have noticed that several reviewers were dissatisfied with the book due to the introductory treatment of Java and JCo. I would like to stress to all current and potential readers that this is a book written for the SAP developer, specifically someone well-versed in ABAP but who has had little to no exposure to Java programming.

The world of SAP development tends to be somewhat insular, with the bulk of commonly used tools provided explicitly within the SAP suite (ABAP Workbench, Menu Painter, Screen Painter, etc.). In my experience, many strict SAP developers have never been exposed to open source development technologies and struggle to gain entry into that world. The specific "open source" focus of this book is intended to demonstrate how these technologies can be used within an SAP environment.

If you are an SAP developer with an interest in broadening your development skills, I would definitely recommend checking out my book. If you are an experienced Java developer looking for an SAP JCo reference, I would pass on this book and check out the various articles and postings available on the Web. A good place to start is SearchSAP.com, where I have posted a number of articles and expert advice on the targeted use of connecting Java applications to SAP via SAP's Java connector, JCo. I also welcome questions/comments via email at austin at opensourceguru dot com.

1.0 out of 5 stars Don't be mislead by the title...., August 6, 2004

By	K. Pokkinen - See all my reviews (REAL NAME)

This book was such a waste of money!

I don't want to read about general, simple concepts regarding Java on SAP that I can easilly read in either the SAP Java documentation or any standard doc for different related products.

When one buys a book like this you would expect to get some information out of it that would be hard to find or put together from other sources. Not reworked text from standard sources discussing the MVC pattern or Struts.

The only audience that could have any, even minor, benefit of this book is the SAP developer who hasn't heard about OO or Java before and just wants to quickly understand some of the basic concepts (without any specific details).

1.0 out of 5 stars not useful, March 29, 2005

By	F. Oelschlager "techman" (Virginia, USA) - See all my reviews (REAL NAME)

This book spends the bulk of its content addressing basic and well documented java and web application concepts rather than the SAP JCo. The book also spent way too much time on the treatment of open source internet technologies.

There is more sample code and documentation provided for plain old Java programming than for SAP specific Java issues and concepts. The samples that are there are also overly simplistic.
