Actually when i place the jasperreports1.2.1.jar in iReport 1.2.8 lib dir and try to compile the report nothing happens. no error, nothing, no compile. As soon as i place the original jasperreports1.2.8.jar everything works fine. And also jasperreports1.2.1 is not present in the compatibility list.
