[rules-users] java.lang.ClassCastException: [Lorg.drools.rule.Package; cannot be cast to org.drools.rule.Package

[Mark Proctor]

That's assuming you have done as geoffrey instructed and use the correct classes. Lots of examples here in this unit test, as to which classes to use:
http://grepcode.com/file/repository.jboss.org/nexus/content/repositories/releases/org.drools/drools-compiler/5.5.0.Final/org/drools/agent/KnowledgeAgentTest.java/

So first make sure you are using the correct classes and apis, as per above. Then do as per below, checking your client and server class paths and rebuilding packages on the server.
