[rules-users] Expose JBoss rules as webservice

[Corneil du Plessis]

The short high-level answer is:

You can use JBoss Tools or Eclipse plugins for Drools to create various 
kinds of rules.
You can use JBoss Drools Guvnor to manage rules and create rules.

Before you can create rules you need to provide a data model of some 
kind, typically a collection of Java classes that will be the 'facts' 
that rules are applied to.

In order to execute rules you initialise working memory with rules and 
facts and the rules are fired.

This implies that a lot of what happens is specific to your data model. 
Thus you will have to develop that code that decides how your model 
interacts with the rules.

Drools provides an agent that can interact with Drools Guvnor to 
retrieve the rules instead of using some local storage.
Your code will have to initialise the agent and then rules will be 
retrieved from Guvnor and executed locally.

You can also use integration tools like Apache Camel or Spring 
Integration and invoke Drools from within an integration flow.
Drools Server provides remote execution of rules via a RESTful API and 
other mechanisms for Apache Camel.

Hope this gives you some direction.
