Good to see this news from you. 4 years ago, we were doing some R&D to choose the best Reporting Engine for our project. After a quick search we found JReport with its all claimed features. At that time Crystal report had just started a thread to support java  and JReport seemed considerably better for Java projects. But unfotunately, this company didn't provide a trial version or any detailed document or comparison to help our consider it. The only way was to contact the company by phone, give it all information about our company and then ask for just a trial version or any technical document. You see that it is not possible for an Iranian Company. So, we had to use Jasper and iReport and develop a Report Engine beased on these 2 ourselves.
I think, in these 4 days, you have a better Business Strategy to trust more on your customer loyalty.
That's why I decided to write this and say Congradulate you.
