tedpet5 Posted January 22, 2013 Share Posted January 22, 2013 I have watched a few instruction videos and it seems that I need to supply my subreport a JRDataSource. I thought I did it correctly.new net.sf.jasperreports.engine.JRDataSource($F{pwoMileStones})as the data source expression.compiling gives me "Cannot Instantiate the type JRDataSource".pwoMileStones is a list.First, did I understand correctly and second what do I have to add to my classpath?
