tJasperReportExec Unknown Column Name error

[jhammer98]

Hello,

I'm struggling with a jasper report, It runs just fine in jasper studio, but it fails in Talend. The report takes in a CSV file that is generated from an Oracle query. 

I've read several threads which seem to suggest that my jdbc driver versions are out of sync but I have no idea how to confirm or deny that this is the case.

The message I get is:

Exception in component tJasperReportExec_1 (Report_output_exec)
net.sf.jasperreports.engine.JRException: Unknown column name: OBJECT_NAME......

Could someone please guide me in determining the jdbc versions that I am using?

Thanks!

I was able to fix this by adding column headers to my CSV file and then checking the checkbox on the tJasperReportExec object to use the header line for column names.
