   J2ME development license?
  Do i need to buy or pay some kind of development license if i want to sell java games? (Platform: J2ME)   
  No.shmoove   ;  Only when you use certain APIs on certain Manufacturers' models, you will need a business relationship with them. (Example: MMS API on Motorola A3 and A4 platform phones)Developing in general is (still) free. With all the signing crap going on, though, I expect quite a few manufacturers to close their doors and only allow signed or, worse, certified content.
