I would like to integrate a jasperreport in pentaho but i have a problem with my x action. In fact, when i try to create my x action, i have this error :

Error: JasperReport.ERROR_0003 - JDBC driver not specified.

I suppose that i must put my driver in a folder but i don't know where. (i have put them in design-studio\plugins\org.pentaho.designstudio.editors.actionsequence_2.0.0.34728\third_party\lib)

Thanks for your help
