well i was reading this post and I have the same doubt: and i have a short question: Can I: 1- Can I modify JI (view, bussiness,logic layers) so it suits an a company? without pay for it o make my app GPL? 2- Can I distribute JI with changes in the clients without pay for it? Why in http://www.jaspersoft.com/pr_overview.html say that I must pay.... and in http://jasperforge.org/sf/wiki/do/viewPage/projects.jasperserver/wiki/License say that I can without pay ?????? so??
