Suppose you want to use a particular Drools class for which the class needs to be loaded from a particular address. How can this be implemented in Java?

    • Class.forName("<class_address>")

    • from <class_address> import <class_name>

    • Class.include<class_address>

    • Class.onBoard("<class_address>")


Suppose you have created a stateful rules session, say stateSession, in the Drools engine. How can you execute the rules of the session be technically correct?

    • results = stateSession.executeRules(<mandatory_attribute>)

    • stateSession.executeRules()

    • stateSession.compileRules()

    • results = stateSession.compileRules(<Mandatory_attribute>)


The Drools uses a pattern matching algorithm to match data tuples to production rules. What would happen in case the algorithm tries to join to different fact types?

    • The join action will be terminated with a type mismatch error.

    • Partial matches would be stored by the algorithm.

    • The join action would run without an error but would return an empty table.

    • The join would only store complete matches. If partial matches occur, the join would modify the rule to make it a complete match.
