A couple of years back when I started blogging on SCN I wrote a series of articles about how-to develop extensible Java applications. Inspired by the Business Add-In (BAdI) framework I even came up with a concept to provide extension points for any application running on a Java EE application server such as the SAP Composition Environment (CE).
Shortly after publishing those articles I was contacted by SAP Press asking me to write a whole book about it and so I did. You can read the whole story here.
Well, a few weeks back the book was put out of print... the good news: You can now download the PDF version for free!
- [Download] You can now download the PDF version of this book free of charge! (4.4 MB)
- [Source] Here's the source code (8.7 MB)
Note: While the book focuses on how-to develop Composites based on the SAP Composition Environment the underlying concept purely leverage standard features of Java EE and as such are definitely applicable to other application servers (with minor modifications.)
Matter of fact I have been thinking about porting the whole extensibility framework to the 2.x branch of SAP HANA Cloud - stay tuned!
