[rules-users] adding process to an empty rule base

[hypnosat7]

I try this:
...
	InputStream stream =
getClass().getResourceAsStream("/rules/demoRuleFlow.rfm");
		Reader ruleFlowReader = new InputStreamReader(stream);
		ruleEngine.setRuleFlow(ruleFlowReader);
..

				PackageBuilder builder = new PackageBuilder();
				builder.addRuleFlow(ruleFlow);
				Package pkgRuleFlow = builder.getPackage();
				ruleBase.addPackage(pkgRuleFlow);

but I have this error:
Caused by: java.lang.NoSuchMethodError:
org.mvel.optimizers.OptimizerFactory.setDefaultOptimizer(Ljava/lang/String;)V
	at
org.drools.rule.builder.dialect.mvel.MVELDialect.init(MVELDialect.java:132)
