I have tried with such changeset file:
<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 change-set-1.0.0.xsd'>
<add>
<resource source="file:D:/jbpm" type="BPMN2"/>
</add>
</change-set>
And such kbase
<jbpm:kbase id="kbase">
<jbpm:resources>
<jbpm:resource type="CHANGE_SET" source="classpath:beans-bpmn-changeset.xml"/>
</jbpm:resources>
</jbpm:kbase>
But at runtime I got error that change-set-1.0.0.xsd couldn't be found , it it exists in knowledge-api-5.4.0.Final.jar that is in my WEB-INF\lib\ folder.
