I need help with this error when executing the report on the server. In local the report works well but on the server the report is not executed. And then the following error.
I use Sql Server 2008. JasperServer CP 6.3.0. Jasper Studio 6.3.1.final
Once you upload a report to JasperReports Server, you won't be able to run it from Jaspersoft Studio.
Check if you connection to sql server is working properly by selecting "Test Connection".
From the supported platform documentation, SQL Server doesn't seem to be supported. (page 5)
