How to Make Mobile Games Using Java

Do you have a game that should on phones supporting Java? If so, read up on this. There's a few blockers on your way.

Steps

1
Understand regular Java game-making. Try to create a desktop version of your game first.
2
Know the limits of J2ME. J2ME is the JRE loaded on Java-supported phones. It's limited in some ways.
3
Know the limits of the phones you're targeting. For example, some phones have J2ME 1.5.
4
Test it. There's more limits in J2ME, and possibly your target phones. Testing can benefit greatly, if your game is big enough; you may want to pick a few testers before releasing.
5
Sign the JARs. VeriSign and StartCom (just to name a few) offer code-signing certificates.
6
Distribute it. Using forums, file hosting sites, gaming sites, and other resources to your advantage.
