Policy Error

Hi;
   I am using Visibroker for Java. I am getting below error:

Exception - ActivationListenerImpl = org.omg.CORBA.PolicyError: There
is no PolicyFactory Registered for type 37

        at
com.be.gdc.eai.lab.tibco.space.emulator.issgCPRClient.main(issgCPRClient.java:46)


I tried running as
java -Dvbroker.orb.enableBiDir=client ClientName

but still I am getting this error.

I am new to CORBA and dont know much. Sorry if I am asking trivial
question.

Regards
Hemang
