[rules-users] Clarification needed on Workbench

I need some clarification on Workbench. First, I'd like to use Workbench to allow business analysts create business rules to manipulate entity classes through the UI. Then, I'd like to export the rules from Workbench to a rules that will be loaded into our application for use by our Drools bean. Ifs this possible? Second, can rules reference EJBs or perform JPA queries? Thanks.
