[rules-users] OptaPlanner Guvnor integration

Hello, How Optaplanner and Guvnor should be integrated? I am using Drools 5.5.0.Final. I have configuration with spring so I have access to KnowledgeBase. I found in documentation: 5.3.4.2.2. A RuleBase (possibly defined by Guvnor) solverFactory.getSolverConfig().getScoreDirectorFactoryConfig.setRuleBase(ruleBase); How I can get rule base? (If it is correct way do integrate with guvnor) Thanks,
