license is LGPL. You can use XXX to develop every comercial project than you want. The unique forbidden thing is developing your own comercial version of XXX.
LGPL license, like Hibernate, is for free in comercial project. What is "developing your own comercial version of XXX" ?

It means you can't modify Hibernate and sell it as a commercial product (e.g. "Sleeping Beauty"), but you can sell your application code which uses Hibernate (for example an accounts system or bulletin board).
