Re: [rules-users] Problem Setting globals in drools session
Having it twice in the classpath would make no diffence (at least with the default java
classloader) as only the first one in the path is used. Having multiple copies of a class
in the classpath is generally not a good idea because it leads to confusion, but it would
not cause this behavior. (multiple classloaders would, though)

Looks like you have twice in your classpath the class ulb.mfe.srabre.ra.BREINTERFACE :)
If I were you, I'd check that...

Objet : [rules-users] Problem Setting globals in drools session
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();
}
}
