**Rishad** · 05-09-06, 08:25 AM

So you want to run Java applications and games on your Pocket PC? Maybe a game that you like so much on your cell phone and want to be able to play it on your Pocket PC? Then read on..

IBM recently released WebSphere Everyplace Micro Environment 6.1, which offers a Java 2 Micro Edition (J2ME) runtime for the Pocket PC. It is a long awaited update which works well on both Windows Mobile 5.0/2003 and on VGA/QVGA devices.

Download IBM J9 from HERE.

Menneisyys has written an excellent review on it. Check it out if you are having problems installing it or just want to know more about it.

A special thanks to discord for posting the new release information on the board.

Is there a SDK for this? I'm quite a keen Java programmer, so I'd love to start churning out apps for myself (and maybe others) for my Ax.

Trial version for runtime?

Sun, I see you handed the PocketPC platform to M$... 1 reason to completely forget about you.

It'll be able to run all standard MIDP2 midlets or CDC/PP apps (including almost all JDK1.3 apps). That is, you don't need a specific SDK for it - standard ones will do.

Yup, Sun has made a cardinal mistake of neglecting the Pocket PC platform. While Java on other mobile platforms ("dumb" mobile phones or, to some degree, even Symbian) is the leading game/software platform, it is pretty neglected on the PPC, compared to Compact Framework.

And it's a shame... I wrote a game on the PocketPC platform (PocketGriddler), which I first programmed in Java (on my PC).
Then, I realized that no user-friendly Java VM existed on the PPC platform.
So I ported the whole game to C# and .Net, which means that it's awfully heavy to install (this .Net Compact Framework is not at all compact), and that it is not portable at all (e.g. on an Apple or Linux machine).
Now that the J9 VM is finally released, I may consider porting PocketGriddler back to where it should have stayed : the Java world ;)

is there java program for the x30?

Menneisyys · 05-11-06, 02:58 PM

You can run any Java VM on the x30. What do you need it for? Applets? Midlets?

Please follow my articles - I've posted a link to a decent tutorial on downloading the stuff some weeks ago. It's at http://forum.xda-developers.com/show...97&postcount=3
