Re: [eclipselink-users] Jasperreports and a jpa based java se applicatio

[sirdeaz <frederik.didden@xxxxxxxxx>]

Hi James,

Thanks alot for responding. 

I've fixed the bug by updating to the latest version of eclipselink!

The application compiled just fine, the error occured during runtime.

The report was working before I ported my application to jpa. I was using
plain old jdbc before.

Regards

Frederik
