6:24 p.m.
Greetings all,
I have the following Java code and rule. When executed I get an "Unexpected
Global" exception (see below). What am I doing wrong?
....
@In WorkingMemory wm
@Logger Log log;
public void calculate() {
wm.setGlobal("logger",log);
wm.insert(calcResult);
wm.fireAllRules();
}
rule "Calc"
when
$c : CalcResult();
then
log(drools.getRule().getName(),log);
// Do calculation
end
function void log(String msg, Log log) {
log.debug(msg,new Object[]{});
}
When the calculate method is executed I get the following exception:
java.lang.RuntimeException: Unexpected global [logger]
