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

[Davide Sottara]

The class org.drools.builder.impl.KnowledgeBuilderFactoryServiceImpl is in drools-compiler.
It is very likely that there is still some configuration issue.. even if you removed the explicit
dependencies, are the servicemix jars still on the classpath?
Moreover, using servicemix-drools 5.1.1 seems to suggest that it would include/reference drools 5.1...
Can you try servicemix-drools 5.5.0?

http://mvnrepository.com/artifact/org.apache.servicemix.bundles/org.apache.servicemix.bundles.drools/5.5.0.Final_2

afaik, this integration piece is not maintained by the drools community directly
