I got the Activation from the kcontext and thus, the methods suggested by
Wolfgang,
Thank you guys,

You can use an event listener for grabbing the
org.drools.runtime.rule.Activation from a BeforeActivationFiredEvent and
store it in a global for access by RHS code. Activation's List<String>
getDeclarationIDs() and Object getDeclarationValue(String name) provide
access to variables and what's bound to them.
