About

OSWorkflow is an open-source workflow engine written entirely in Java with a flexible approach and a technical user-base target. It is released under the Apache License. You can create simple or complex workflows, depending on your needs. You can focus your work on the business logic and rules. No more Petri Net or finite state machine coding! You can integrate OSWorkflow into your application with a minimum of fuss. OSWorkflow provides all of the workflow constructs that you might encounter in real-life processes, such as steps, conditions, loops, splits, joins, roles, etc.

This book explains in detail all the various aspects of OSWorkflow, without assuming any prior knowledge of Business Process Management. Real-life examples are used to clarify concepts.
