jBPM comes with tutorials (that are being constantly enahnced) to let users build more sofisticated business applications.
Currently below are tutorials available online
Build and run your first business application starting from scratch.
Enhance your business application with business process that can be executed with directly through REST API of your application or by using Business Central web interface.
Enhance your business application with business assets that execute custom business logic and monitors execution via event listeners
Enhance your business application with JPA entity that will be used both by your business application service and business assets.
Build business application that uses JMS to send information between your business processes. It combines process logic and messaging to provide comprehensive solution to common problems e.g. how to notify other participants of particular event.
Enhance your business application with some dynamic assets that allow more adaptive approach to business logic compared with structured business processes.
Examples are intended to provide fully featured sample business applications that can be used as base start. They are usually more advanced than tutorials as they should provide complete (end to end covered) business goal.
Similar as tutorials there will be more coming with every release of jBPM so stay tuned and keep an eye on Business Applications GitHub organization. Each repository in this organization is fully working example of a business application.
