understanding working of Drools guvnor

can any one plz let me know that how drool guvnor work i went to guvnor documentation but couldn't understand the core logic of how rules are processed and how we can use dr开发者_Go百科ools guvnor in coherence with java code

Basically i want to know how java code interacts with drools guvnor api.

There is very less documentation about latest drool 6. I suggest you watch this presentation by Mark Proctor on drools 6 (Drools Project Lead at Red Hat) and visit his Youtube Channel to watch screencasts of drools workbench and tutorials on building example applications.
