I have a very simple MS SQL stored proc (no input parameters). See below... CREATE PROCEDURE dbo.Test AS BEGIN SET NO COUNT ON SELECT * FROM person END When I use this stored proc as my data source in JasperReports Studio building my report, everything works perfectly. But when I upload it into JasperReports Server and setup the relevant data sources there, I keep getting an error when the report tries to run. Any help/guidance is appreciated. P.S. I'm using the Community Edition of JasperReports Server 6.4.0. Thank you.
