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

[Wolfgang Laun]

The stack dump you've posted does not match the jars you have
"included"; check line 108 in KnowledgeBuilderFactory.java. Looks like
a version mixup in your classpath.

-W

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".
