So, let's talk about some points:
- You should not create a new knowledge base every time you need a
session, because construction of knowledge bases is very expensive. You
would do this at start of application applying Singleton pattern.
- If you already have a knowledge base, you are able to get parameters
from GET or POST using your preferred controller, instantiate your objects
using then and after that pass your objects for a new knowledge session
(stateless or statefull).

Which version of drools are you using? RuleBase, RuleAgent and
WorkingMemory are not used anymore. And, this piece of log makes me think
if the version of Guvnor you are running is different to the version of
Drools you are using in your webapp:
org.drools.
rule.Package; local class incompatible: stream classdesc serialVersionUID =
510, local class serialV
ersionUID = 400
Seems you are using Guvnor 5.1 but Drools 4.0 in your webapp. If you are
just starting with drools, I'd suggest you to use the latest stable version
5.3.
