[rules-users] Error in Drools Fusion Example

Hi, I'm trying to get the Drools Fusion from the download page example to run. But I'm getting the following error messages and I don't know why. ---- File: broker.drl line 31 BuildError: Unable to build expression for 'consequence': Failed to compile: 1 compilation error(s): - (1,10) unqualified type in strict mode for: Statistics Statistics s = new Statistics(); s.symbol = $s; insert( s ); line: 74 BuildError: Unable to build expression for 'consequence': Failed to compile: 1 compilation error(s): - (1,12) unable to resolve method using strict-mode: java.lang.Object.percent(double) services.log( "Drop >5%: "+$sb+" delta: $"+percent($dt)+" price: $"+$pr ); ---- File: Broker.java line: 92 The method add(Resource, ResourceType) is undefined for the type KnowledgeBuilder line: 102 The method setOption(EventProcessingOption) is undefined for the type KnowledgeBaseConfiguration ---- What's the problem? Greetings :) Tina
