Oracle Business Rules as a Composite Service

The general practice of using Oracle Business Rules is to create a set of rules in a dictionary and this dictionary in turn will be invoke by a bpel, which would have been exposed as a web service or composite service. But there are cases where a bpel is not needed and one needs the service of just rules.

In those particular cases, the dictionary themselves can be exposed as a composite service. So a web service would be created which would directly interface with the dictionary. A couple of points has to be noted when doing this and apart from that, its just a normal rules configuration, soa composite deploy and test:

Create an empty composite, just add a dictionary and make sure to mark the dictionary for the below:

When testing the service, it would require the name of the decision function to be passed. Earlier this was taken care by the bpel when we used to drag drop the business rules component and choose the dictionary and decision function:
