[rules-users] How to use global hashmap in drools

[Wolfgang Laun]

In your DRL (quote from the Expert manual):
   global java.util.List list
or a Map or a ...

In the Java code (another quote from the Expert manual):
   List list = new ArrayList();
   ksession.setGlobal("list", list);
or a Map or a...

In your DRL a function
   function setValue(Map map, String a, Integer b){
       ...
   }
I guess you can complete the function. Important: pass the global as a
parameter.
