This book is a complete developer's guide to working with jBPM in a J2EE enterprise environment. It is packed with examples of implementations that will provide you with all the experience needed in real-life implementations. Extensive discussions about how the framework is implemented internally will contribute to creating a robust knowledge of when and how your projects will include this framework. This book is mainly targeted at Java developers and Java architects who need to have a deep understanding of how frameworks behave in real-life implementations. The book assumes that you know the Java Language well and also know some widely used frameworks such as Hibernate and Log4J. You should also know the basics of relational databases and the Eclipse IDE. A brief introduction to Maven2 is included in this book but extra experience might be needed for more advanced usages.
