Helped me to understand and develop BAPIs. Connected to those BAPIs from java.

Nice Java/SAP Examples, But No Web Enablement Alternatives

Reviewed in the United States on June 3, 2000

I found parts of this book interesting, some smaller parts even valuable. But there were large parts that, to me personally, were not at all valuable. One topic I found totally lacking, and suggest finding another source of information.
40% of the book was used for plain old Java or HTML stuff (unrelated to SAP). I didn't need this stuff because I have a nice Java book (Cay Horstman) already. And I'm beyond the summary level HTML found in the appendix. If you know C++, this relatively quick treatment of Java might work for you, but I'm thinking an experienced C++ coder would want a real meaty Java book. And if you are not already fairly familiar with an OO language, you're likely not going to get very far with the relatively light treatment of Java found in this book. So I'm not sure what the target audience is for this substantial chunk of this book (calculated after allocating-in the 20 page (!) table of contents, and other general pages).
A slightly larger percentage of the book was dedicated to SAP related topics which I consider useful. There's overview, positioning, definition and architecture stuff that's interesting and useful to someone trying to look outside of your SAP servers. The book offers to walk you through setting up SAP Automation, which might prevent a 'gotcha' or two. Then there are some 'simple' Java examples, and some more complex Java examples... all doing something with SAP. These could easily become the basis for a 'real' application. SAP offers examples in their documentation, and you can find some examples in some of the journals, but this book gives you quite a few examples that do different things with SAP. These example programs may also include a more complete description of what's happening in the code than other examples you may find.
Then the topic of web enabling comes up. We have an 'ITS' chapter, a 'this is why you need ITS' chapter, and a 'here are ITS headaches' chapter (I've used poetic license here, of course). Do yourself a favor and look closely at some of the alternatives before you jump into ITS. The information presented seems similar to SAP AG's propaganda, er, I mean view, but there is much more to consider than what's presented here. We get a few 'cons' for ITS, but the point is never driven home that ITS is basically architected just like SAP GUI, and in so doing, you have serious logon resource issues if you have more than a few users. So if you want to do anything 'serious' with web enabling, you need to look at HAHT Software, SilverStream, and Visual Edge. Right now HAHT (an SAP partner) is the only one with a development environment and runtime platform specifically targeted for R/3. And, get this, the tool codes Java for you. You just add a bit more Java to make it sing your tune. But check out these other packages against your requirements.
The final part of the book (17%) had some listings which I consider 'convenience' items, at best. This included listings of methods in the 'rfc' and 'rfc.exception' packages. I assume that there are javadocs out there, which cover this material. There might have been a little bit of wisdom thrown-in here, beyond what one would typically find in the javadocs (especially if SAP wrote the javadocs -- jab jab). The BAPI listing, though, seemed not to have much beyond what's in SAP.
So in summary, I think that the treatment of how one might proceed in web enabling SAP is not at all sufficient, and the large fraction of pages with plain old Java, and listings didn't do much for me. But the Java code examples that interact with SAP are valuable, and the background and architecture discussions provide a good foundation for a learner.
About me: I've been an SAP consultant since 2.2, and last year started coding in Java. I've been moving away from the traditional interfacing (ALE/IDOC), and have been moving into BAPI/RFC and web enabling SAP (with Java, of course!)
