Hello to all, I have a problem with the Database Connector with Microsoft SQL Version 15.0.2000.5: Every time I try to execute the Microflow with "Execute Query" I get the following error: Error in execution of monitored action 'RegularClientAction' (execution id: 1604584344210-5, execution type: CLIENT). NoClassDefFoundError occurred for class 'javax/xml/bind/DatatypeConverter'. Please make sure the userlib folder of your project includes the correct library which contains this class. -------- java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter at

Thanks a lot in advance. -Pascal
