Finally I know at least somewhat where I am in mid air... well most of the time ;-) Trying to get "air"wareness...

This is the first book that I have officially been named as an author. The ABAP Developer´s Guide to Java is a book which aims at SAP ABAP Developers, who want/need to get into Java and J2EE development - as the new SAP technology platform SAP NetWeaver heavily relies on J2EE technology.The quote from the sales catalog reads as follows:
"You already know the ropes in the world of ABAP programming. Now, how can you utilize those finely tuned skills to speed up your journey on the road toward Java proficiency?
This all-new reference book is an indispensable guide for readers who need a rapid and in-depth introduction to Java. Detailed insights and step-by-step instruction help you leverage ABAP development skills you’ve already honed, for a smooth transition to Java. The authors highlight each fundamental aspect pertaining to the development of business applications in both languages, and the differences as well as similarities are analyzed in detail. This must-have resource helps any serious developer learn exclusive techniques to master development tools and objects, application design, application layers and much more. Learn about Beans, OpenSQL for Java, JDBC, Security, and that’s just for starters. This unique book helps you save countless hours of trial and error and avoid costly mistakes while quickly advancing your essential Java skills."
With this book I have been responsible for the overall project management during the decisive phases. Also I have written a majority of the chapters. In this sense my work with this project has produced parts of chapter 2, 4 and most or all of chapters 5 through 7. Although the book was written mostly in a hurry and besides daily work, I am pretty happy with the result.

A Component Framework Based On Web Services
Web Services are an XML-based set of technologies to enable remote function calls over about any web-related transport protocol like HTTP, SMTP or FTP. As it is a specification based on the maxim of extensibility and customizability this technology is also suitable for communication across platforms and programming languages. The key feature that both IT analysts and the businesses put their hopes on is the possibility of supporting the automation of business processes even across company borders and the aggregation of these processes to complete workflows that follow the mechanism of recursive composition which means that a workflow itself can be exposed as a business process to be reused within a more comprehensive system.
All concepts of Web Services are based on standards that are developed and confirmed
by consortiums of independent organizations like the W3C and OASIS consulted by the
industry leaders of infrastructure and ERP software like Microsoft, IBM, SAP, VeriSign and many more. While the terms of service location, registration, data transportation across systems, formatting and embedding into other protocols has been dealt with successfully, security, transaction and meta-descriptive standards have yet to be finalized.
On the basis of this scenario this document develops a concept of a distributable,
scalable, reusable and extensible component architecture that uses Web Services as its foundations. The theoretical model is then implemented using the server-sided scripting language PHP that itself has become the most popular server-sided scripting language for web-related purposes over the last three years. The component architecture thereby adds a model for business logic, encapsulated within distributable entities to the overall concept of multi-tiered application design, like it is popular with enterprise level applications built on the foundations of e.g. J2EE, Microsoft .NET or SAP NetWeaver.
The applicability of the concepts and the model presented is proved through both
example implementations of the basic features and a case study that creates a context
for a Web Service based application.
