Hi,                                                                                                                                                                                                                                                                                                                            
Im using jasperreport (on server) to generate pdf files for my customers and sending them as reports every day..  
But im woried about licencing issues of  using iText 2.1.7 in commercial software.                                                                                                                                                                                                                                             Can i still switch to jasperreport 6.0.0 and use iText 5.5.0  (with exception in licence) as lGPL library?
And just keep using jasperreport 6.0.0?                                                                                                                                                                                                                                                                                                 
thank you
