Need help with the array of jasperreport


I have a report that is I need to create a xy chart with. I have done several charts and have not come back with this error.

The report compiles fine. When I execute the chart within the application I get the following error:

Null 'orientation' argument

i was having same issue. My problem was that i had old version of jasperreport.jar on my classpath. Verify your jars
