Re: [rules-users] Drools 5.5 java.lang.ClassCastException: org.drools.compiler.rule.builder.dialect.mvel.MVELDialectConfiguration cannot be cast to org.drools.compiler.DialectConfiguration

I had a similar problem once related to having two sets of drools dependencies in the classpath. Have you tried removing the org.apache.servicemix.bundles.drools dependency from your pom file? if this is a servicemix Service and you can't remove that from the actual runtim e, you might try a PARENT_LAST class loader configuration -- View this message in context: http://drools.46999.n3.nabble.com/Drools-5-5-java-lang-ClassCastException...
