    package t2.state

import t2.state.User;
import java.util.Map;
import java.util.HashMap;

function Map createMap(String key,Object obj){
 Map m=new HashMap();
 m.put(key,obj);
 return m;
}

rule "boot"
 dialect "mvel"
 when
  u : User(age==0)
 then
  System.out.println(" new Usesr");
  kcontext.getKnowledgeRuntime().startProcess("p1rf",createMap("user",u));
end

rule "inc user age"
