Re: [rules-users] Problem Setting globals in drools session
Does your application use multiple classloaders? It's possible for two instances with
the same class definition to not have "equal" classes if the class is loaded
twice from different classloaders.

Hello everybody,
When I try to sett my globals I get this error
2010-07-05 21:26:04,531 ERROR [STDERR]
java.lang.RuntimeException:
Illegal class for global. Expected
[ulb.mfe.srabre.ra.BREINTERFACE],
found [ulb.mfe.srabre.ra.BREINTERFACE].
Can anyone explain to me what does this error mean please
.
MY DRL FILE
package ulb.mfe.srabre.rule
import ulb.mfe.srabre.ra.BREINTERFACE;
import ulb.mfe.srabre.ra.DROOLSSLEEAgent;
global ulb.mfe.srabre.ra.BREINTERFACE BRERAInterface;
global ulb.mfe.srabre.ra.DROOLSSLEEAgent DROOLSSLEEAgent;
rule "MaxBtsAlarmrule"
dialect "mvel"
when
$B : BREINTERFACE()
then
System.out.println(" HELLO ");
end
my code
public void Insert(Object fact) {
try{
KnowledgeSessionConfiguration
sessConfig =
KnowledgeBaseFactory.newKnowledgeSessionConfiguration();
sessConfig.setOption(ClockTypeOption.get("pseudo"));
StatefulKnowledgeSession
session =
knowledgeBase.newStatefulKnowledgeSession();
session.setGlobal("BRERAInterface", this.breinter);
session.setGlobal("DROOLSSLEEAgent", this.droolssleeAgent);
session.insert(this.breinter);
System.out.println("Fact is now
inserted");
session.fireAllRules();
} catch (Throwable t) {
logger.info("sml couldn't set
up a session");
t.printStackTrace();
}
}
