JBoss.orgCommunity Documentation
All releases can be downloaded from SourceForge. Select the version you want to download and then select which artifact you want:
bin: all the jBPM binaries (jars) and their dependencies
src: the sources of the core components
docs: the documentation
examples: some jBPM examples, can be imported into Eclipse
installer: the jbpm-installer, downloads and installs a demo setup of jBPM
installer-full: the jbpm-installer, downloads and installs a demo setup of jBPM, already contains a number of dependencies prepackages (so they don't need to be downloaded separately)
If you like to take a quick tutorial that will guide you through most of the components using a simple example, take a look at the Installer chapter. This will teach you how to download and use the installer to create a demo setup, including most of the components. It uses a simple example to guide you through the most important features. Screencasts are available to help you out as well.
If you like to read more information first, the following chapters first focus on the core engine (API, BPMN 2.0, etc.). Further chapters will then describe the other components and other more complex topics like domain-specific processes, flexible processes, etc. After reading the core chapters, you should be able to jump to other chapters that you might find interesting.
You can also start playing around with some examples that are offered in a separate download. Check out the examples chapter to see how to start playing with these.
After reading through these chapters, you should be ready to start creating your own processes and integrate the engine with your application. These processes can be started from the installer or be started from scratch.
Here are a lot of useful links part of the jBPM community:
