I managed to fix this problem. It's a problem to do with JasperSoft Studio version. In my case I use Netbeans and JasperSoft Studio 6.11.0 I was getting an identical problem to what you posted, so I expect solution could be the same. In my netbeans project POM I was using net.sf.jasperreports Version 6.9.0, Updating this to Version 6.11.0 solved my problem Hope this solves your problem.

Hello, have you gotten any solution? I got a similar challenge too. Same error. Tried also the suggestion here unsuccessfully.
