I have seen through a bit of the book's 332 pages and i must say that it is a true gem due to the many powerful extensions tutorials that allows ADempiere to talk to so many popular and important apps out there. The earlier Part I of the book revisits all the best practices of ADempiere such as how to set it up, meddle with its insides, both Java and Ajax clients, up to extending its Application Dictionary (inherited from Compiere, with thanks). It does not touch on any ERP subject matter functionals though. It is thus really a technical cookbook from the beginning.
In the Part II, it goes deeper and even though it refers to our Web Services it is laid out in more concise format of delivery which i find it more reference-friendly than our sometimes clumsy Wiki. It is easier with its clear reference table such as where to find what SQL to get what AD object to feed which Web Service item.
It also take our JasperReports integration but with more ideas in this book than ours, laying out clearly two case examples - one via AD Report View and one via a direct call from Report & Process.
The Mondrian integration is quite too low-level for my liking. I mean I would prefer the use of Pentaho or Palo or Talend instead of the primal Mondrian, but in that respect it is a good proof of concept, in that if you do master this part for Business Intelligence interfacing, you should be able to tackle any higher ground.
The topic on VirtueMart opens up ways to integrate to a whole family of e-Commerce layers out there including Magento and osCommerce. This topic includes teaching about setting up the needed ActiveMQ and Joomla layers, going very technical with clearly written snippets to make it all work. (I haven't tried it personally but now am very encouraged to do so). The author of the book, Ajit Kumar (stranger to me) sounded very confident (hmm.. must really try it out to really know).
In short this is meant for the true developer who has to go under the hood in many parts of ADempiere and make it work for any challenge out there. At least it is a very good start in just 300 over pages. Again, it is not an ERP subject-matter manual nor help a lay user how to use ADempiere. For that you can buy the other Packt UK book written by Bayu Cahaya.
