jBPM allows users to extend the default process constructs with domain-specific extensions. These extensions, also called domain-specific service nodes, simplify development in a particular application domain in that they are:
- declarative (what, not how)
- high-level (no code)
- customizable to the context
So far incorporating domain-specific service nodes was only possible within the Drools Flow Eclipse Plugin. (For more info check out the jBPM docs as well this great video).
We have now added support for domain-specific service nodes to the Oryx web designer. This allows users to create fully executable BPMN2 processes including domain-specific service nodes, all inside Guvnor.
This video shows how you can use can create new or use your existing domain-specific service nodes inside the Oryx designer (quicktime movie available here). You can also start playing with this by downloading the designer from here as well as Guvnor 5.2.0.CR1.
