Hi All,
When I access the drools-server by URLConnection, I've always got such errors:
WARNING: RuleAgent(default) EXCEPTION (Mon Feb 02 16:09:46 CST 2009): org.drools.base.BaseEvaluator; local class incompatible: stream classdesc serialVersionUID = -7767879457606879276, local class serialVersionUID = -7149415669283058142. Stack trace should follow.
