We are in the early stages of developing a custom solution using jBPM and wanted to test what we have so far with 6.0.0.CR2.
We have a KnowledgeBuilder that we add our resources to, and then create new KnowledgeBase from. However org.kie.internal.KnowledgeBase is deprecated even though it's mentioned in the current KIE API 6.0.0.CR3 Javadoc as the interface to use.
Is there another interface that we should be using instead? Is the Javadoc incorrect and the typical way to load a resource has changed from the page I linked above?
the replacement is KieBase.
Although you could look into RuntimeManager for actual building and managing KieBase and KieSession for you. Here you can find some examples on them and soon some documentation/blog posts will be available too. While waiting for it feel free to post your questions here.
