Hi! I would like to use the BatchExecution as an interface between EJB's. The BatchExecutionCommand is serializable. But when I try to get back the QueryResults I get a: java.io.NotSerializableException: org.drools.runtime.rule.impl.NativeQueryResults can this class changed to extend Serializable? Should I do it in a different way? Thanks! Juergen -- View this message in context: http://drools.46999.n3.nabble.com/Need-to-Serialize-QueryResults-tp402127...
