Re: [rules-users] Exception in thread "main" org.drools.ProviderInitializationException

PS: Next time, requesting a solution "ASAP" might induce me to sent an invoice.
PPS: Note that you are emailing to a list, so don't add statements
that it may contain "proprietary, confidential or privileged
information".
