Solved Got it: driver issue. The client used a jdbc:jtds driver, not available on the server, which works using a jdbc-only driver. I wish the error message was more meaningful, but that's it. Kind regards, Niki

Hello, I need to fill a single report with data from two different databases. I searched and found these instructions: https://community.jaspersoft.com/wiki/how-use-multiple-data-sources-jaspersoft-studio-or-jasperreports-server https://community.jaspersoft.com/wiki/multiple-datasources-ireport-lists-tables-and-subreports So I followed them and I could get it to work locally, in Jaspersoft Studio. When I deploy it on the JasperReports Server, though, it does not work, returning this error: I am running JasperReports Server 7.5.0, Build: 20191206_1440. I searched the Community for hints, but I could not find what I wish for. Here in attachment a simple report that (with the correct connection string, that I changed here for obvious reasons) works fine locally. Thanks for your help. Kind regards, Niki
