This is relatively easy but your PSP does need custom firmware. The type of java games are, well any but some work well and others don't. One main reason people do this is that you can run opera mini on your PSP using this.

    Yeah, ReCreate is right. A usual Java SE program doesn't share anything of the user interface with a Java ME program.. 
    You don't just need to recompile it, you'll need to make the interface all over in LWUIT (my favorite) or LCDUI (meh..) and then compile it..
    For the programming and compiling, i recommend the NetBeans full version (with the Java ME features).. but if you dont know what you're doing, its probably best to just find java me games.. =/

    I develop Java ME games, and even i wouldn't have all that trouble to convert a game from SE to ME.. ouch

    i think it's impossible. think about the screen resolution of the application. it might quite big, so the phone doesn't have ability to run the application. but probably you're able run java application on your pocket pc by windows mobile, by installing java program to your pocket pc.
