Sorry to jump in Teodor and karmayogi :), (Also sorry if this is the second post, my browser had a 'moment' back there :blush:) If I write a web application using JasperReports jars and rent it out to users, then , as I understand it, I need to : - Allow users to download the jars & source code Allow users to see / download the LGPL Not modify the code in the jars Do I need to add a marker to any report showing that it is based on LGPL and yadda yadda yadda... ?
