Somewhere in your input data has met a NullPointerException.

Check your input data which you fill in your table in the report template.

If you don't know which field causes the exception. Try to remove one by one to find it.

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

[charlesm2009_1]

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.
