[rules-users] Problem Setting globals in drools session

[Greg Barton]

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...

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();
   }
   }
