Rules Service - how to connect to rule repository?

[magick93]

Hi

I'm interested in building a Rule Service - as outlined in this article - https://docs.jboss.org/author/display/SWITCHYARD/Rules+Services

However, this article shows how to load a rule from a .drl file. I, on the other hand, use Guvnor, and a rule repository to store rules.

How then, can I load rules from the repository?

Thanks and regards,

The same article mentions lower down:

Using a KnowledgeAgent

A Drools KnowlegeAgent provides automatic loading, caching and re-loading of local or remote resources. An example of a remote resource would be one hosted by Guvnor.  Enabling resources to be managed by a KnowledgeAgent is easy, and can be enabled simply either via annotations:

@Rules(... agent=true)

or via XML:

<implementation.rules ... agent="true">     ... </implementation.rules>

It does leave out however that you also need to configure a ChangeSet.xml file:

<rules:resource location="META-INF/ChangeSet.xml" type="CHANGE_SET"/>

and an include a ChangeSet.xml file that looks like this:

change-set xmlns='http://drools.org/drools-5.0/change-set'

    xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'

    xs:schemaLocation='http://drools.org/drools-5.0/change-set http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/main/resources/change-set-1.0.0.xsd' >

    <add>

         <resource source='http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/sandbox.michele/LATEST' type='PKG'

         basicAuthentication="enabled" username="admin" password="admin" />/>

    </add>

</change-set>

Thanks Jeff.  I've added a "Using a Rules Repository" section to the documentation, right under the "Using a Knowledge Agent" section.
