Error marshalling NoClassDefFoundError class in Guvnor
When running Guvnor (I've tried 6.0.0.Final and 6.0.0.CR5) on both Tomcat 6 and 7, I tried running the Hello World rules from the Drools examples. After packaging the jar for the Drools example and uploading this to Guvnor, when I try to build my project I get this error
