Answer 1

The report is empty on JasperReports Server because, most likely, you have not selected a data source when published it.

You have created and tested the report with the Sample DB that is shipped with Jaspersoft Studio. The same data, or in this case the same database table with the same structure, must be accessible to the Server, too. You specify that when you publish the report.

Luckily, there is a data source on the Server that has a similar table structure to the one in Studio. What you need to do is to republish the report in the same location and in the Report Publishing Wizard to select Data Source from Repository and either enter this path:

/public/Samples/Data_Sources/ExmapleVDS

(the typo is intended) or manually select it by browsing through these folders:

Public > Samples > Data Sources > ExampleVDS

in the Repository Browser dialog triggered by the ... button adjacent to the input text field.

Note: The Server connection in Studio was done with the jasperadmin user.
