Finally some time to do the review.
Let me start with my biggest discovery: the book is written about jBPM3 and not the newer jBPM4. This is not mentioned on the Packt publishing site. Too bad, a jBPM4 book is still missing in the offering.
Conclusion
PRO:
- Probably the best developers book about jBPM3 so far. Compared to BPM With JBoss jBPM, this book is aimed more for developers and goes further into the technical details.
- The book brings beginners to an advanced level. It does not bring advanced users to a further level.
- I would advice beginner jBPM developers to start with this book. It emphasizes on getting the basics right but does not hide the more advanced features.
- The explanation is good, providing context and sufficient examples.
CON:
- Their is definitely a language impedance for the writer. Sentence are basic, language constructs are poor and almost all the sentences start with “You’ll see” or “You will”. Very sad to see this poor editorial from Packt Publishing. Clearly no review by them, and I blame them and not the writer.
- Some content is noble, but also beyond the goal of this book. Chapters 1 & 2 are not interesting to jBPM Developers. They cover a motivational speech about why you should care for open source, what is BPM and how to create your own BPM engine.
- Some must have advanced topics are missing: integration with test frameworks, exception handling for example.
As stated, I do recommend this book for new jBPM developers since it does provide a rather good learning curve for new developers. Don’t expect this book to be a reference, therefore it is much to verbose and not advanced enough. The userguide of jBPM is a better reference.
Kind regards,
Andries

This is the first book that explains the Spring integration within jBPM. I’ve managed to see a copy of the long explanation. I’m impressed with the explanation and it is very understanding and complete! Saves me the trouble of testing the integration on Spring3 aswell 
I’m also referenced by name in the book, a nice pitch for me! I’ve ordered the book and I’ll publish a review later, but from what I’ve seen it looks very promising.
It’s written by Gary Mak of the best-selling Spring Recipes and Josh Long, an expert Spring user and developer.

Packt publishing is sending me a review copy of the jBPM Developer Guide. I’m looking forward to this book. The summary promises among others:
- Key concepts of Business Process Management to understand how the community leads and implements open source software
- Gain deep understanding of JPDL, the preferred process language, to know how your processes must be defined and implemented
- Convert your projects into fully featured applications with advanced jBPM features such as the persistence service and human task mechanism
- Understand the framework’s behavior in different environments
- Create and configure Human Task activities to model situations where human beings interact with the process
- Understand how the framework handles information that flows through your business process
- Configure the persistence service to reduce risk and perform successful implementations with jBPM
- Improve your process definitions using nodes
- Configure the Eclipse IDE to start modeling your processes
Keep an eye on this blog to read the review.

Ever wondered who is “Developer of the month?”. I’ve found this great app that does just the thing… http://www.statsvn.org/ .
I’ve taken the liberty to run it on the jBPM4 trunk, check it out here!
From the quick start:
Quick Start
* Download the latest release from http://sourceforge.net/projects/statsvn/
* Expand the zip file into some directory, e.g c:\statsvn
* Check out a working copy of the desired SVN module into
some directory, e.g. c:\myproject.
* Change into that directory and type
'svn log --xml -v > svn.log'
* Change back to the c:\statsvn directory
* type 'java -jar statsvn.jar c:\myproject\svn.log c:\myproject'
* Open c:\statsvn\index.html in your web browser
Regards,
Andries

As a tech lead, on occasion I’m faced with the question:
- How well should something be implemented? Is it OK if it just works, or do I need to refactor and make it more “generic”?
- When is it done?
- …
The rule I live by is as following:
If I write code, I make it so that I, or anybody else, could reuse that code with ease.
This means:
- Write good documentation, mostly on WHAT it does, not HOW. It’s a whole lot easier to read code if you know what the result should be. It’s not easier to read how something works, then read the code and then guess what the desired outcome should be.
- Write clear code. Hacks or fuzzy lines should be refactored. Hacks tend to get more hackish with old age.
- Create loosely coupled code. Code with a lot of dependencies can’t be reused. Make it a little more abstract if you have to.
- Use generic names. Don’t write classes named MyProjectDataValidatorUtils.
- Don’t hard code project specific stuff. Use property injection instead.
This does NOT mean:
- Write code that can do a lot more than is needed for the project.
- Premature optimization. If I know my project will only have 10 entities, I’m not testing for a million…
- Over document it. We are still developers. Write to many and you won’t really read anything at all six months from now.
If done a handful of projects and I reuse a lot of stuff from old projects. The fantastic thing is, that these building blocks have the tendency to improve over projects. Every project needs specific functionality, and by adding those to existing blocks you end up with some really powerful, reusable parts.

Nils Preusker, Joram Barrez and I have uploaded some demo’s on jBPM4. If you like to start fast and use demo’s which integrates different technologies, this is a good place to start.
You can find the demo’s at the jbpm svn.

I get a lot of questions about the Spring integration, by mail and as blog comments. Almost all these questions can be answered by reading the developers guide of jBPM4, which you can find here .
If you still have questions, please post them at the forums. My spies (c.f. Joram) at JBoss keeps me posted of any Spring related topic, and I’m more then happy to answer the questions there.

Last week I learned all about svn properties. One of them is the svn:needs-lock property. This forces you to require a lock before you can make a commit.
Very handy if you have binary files in your project, which is under version control. Binary files can’t be merged, so if multiple developers are editing this file the slowest will have a problem.
I use it for enforcing the Excel sheets which contain the testdata for DBUnit. Subclipse show a nice icon which indicates you need a lock. Subversive does not show this, but, as does Subclipse, let’s you open the file in readonly.
