I have a Rapidminer process of classification taking the input with "Read Database" operator. The process is well executed in Rapidminer studio as well as via JAVA class in Netbeans. But when I try to call that java class via JSP, It throws following exception:
com.rapidminer.operator.UserError: The dummy operator Read Database (replacing jdbc_connectors:read_database) cannot be executed.
How can I resolve it?
