I used DatabaseConnector to get data from a table stored in MS SQL Server 2014 Express version. I am using  Mendix Modeler 6.10.1  I created a Microflow with Execute query activity.  jdbc url =  'jdbc:sqlserver://localhost\\EXP2014;database=AdventureWorks2014;' I run the application locally and when I try to execute query I am getting an error. See the log below. MS SQL Server is accessible through jdbc driver. I tested it by building a simple java application that can connect to the server and get data form a table. But from Mendix I am getting errors. Do anyone have any idea what can be wrong? Jacek  ============================================ An error has occurred while handling the request.
