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.

Step 1: What Ya Will Be Usin'!

Hardware: A Psp ( custom firmware ONLY )
A PC
A PSP usb cable

Software: PSPKVM (http://www.pspkvm.com/(Click On Downloads)
Optional: Java Games (http://www.getjar.com/software/Sony-Ericsson/W850i)
Opera Mini (http://www.getjar.com/products/3334/OperaMiniWebbrowser)

Get these things before you continue...

Step 2: Install PSPKVM

Copy "PSPKVM" to /PSP/GAME or /PSP/GAME150 or /PSP/GAME5XX folder.

Depending on what firmware you have or just try each of them and see if they work.

Step 3: Using PSPKVM!

Put The java games in a folder of your PSP ( like: Java Games + Apps )!

Then:

  • Run PSPKVM on your PSP
  • Click Find Applications (By Pressing Start)
  • Then Click Install from memory stick ( by pressing start )
  • Then Go into whatever folder your java files are in ( press O )
  • Then press your java game/app ( by pressing start )
  • Then click J2ME standard (480*272) ( by pressing O )

Step 4: Before You Try to Use Anything!

  • Exit The Application ( if you are on one ) and :

1-Start PSPVKM
2-Go to network set up. Press start to launch
3- click your network name. Press start
4- wait for it to finish and click done. Press start
5-Press Select to go back to the main page
6- Start opera mini!

Note : Your network needs to be configured on your PSP before you do it.

Step 5: And Thats It!

Yay You've done it! Please comment!

    Aaaah Yes,That is where the problems arise....

    I have a number of dictionary applications and games that I use to use on my cell phone but I can'r figure out how to control them on the psp. Spelling is a big problem. So do you know how to do it?

    i got i am writing this comnent on it now

    Cool How do you type? well done for finding it out. If u really are tellin the truth

    when typing in the web adress the up, down, left, right and triangle and squae are all letters and if you hold L you get more choices L and X is delete (i used this alot) then when typing in a coment or something hold L and hit circle untill you get to the engish words you mostly have to mess around untill you get it

    Now all I need to know is how to convert PC based java to Mobile based Jar format... Any ideas?

    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.

    You gotta Re compile it to JavaME

    Have you got PSP headphones?
