Yo ppl, wat's the diff between normal wallpaper and java wallpaper? Can anyone supply some free java wallpaper or sites that provide them?

Posted by: D_RiDE

I would like to know the difference too...

There is a term "wallpaper application" that mean, the Java application can run continously in the background, but that is a VSCL (Vodafone) Java extension. I don't know if it exist on GX21/GX22/GX27. Try the jbenchmark at www.jbenchmark.com, that will display that info at the end of benchmarking (like MIDP 1.0; VSCL 1.1.0).

The link doesn't seem to work...

a java wallpaper acts like an animated screensaver. I downloaded one from FarEastone and it allows you to setup how long you wish the phone to wait before displaying the java screensaver. The size of one of those things are pretty much the same as one java game so I deleted it soon after because I kind of find it useless... Hope this answers your question

Maybe you could upload the java wallpaper so that the rest of us could try it out and see for ourself? Btw since u own a gx-21, could you give some comments on the java ktv on your gx-21? Anyone where we could get the java ktvs on our gx-2x?

Correct me if I'm wrong but i think gifs suck for this phone since the color looks washed out. Why do you think it goes well with the outer display cause its stn. Java wallpapers let you use the full color of the phone so having one of those would be a lot better and more colorful.

did anyone inthe end manage to find java wallpaper??
i been searching for it in japanese sites... i manage to get couple of 504i series java wallpaper (both .jar and .jad) for NTT Docomo but it wont let me download to my gx22 even if i upload them to my own wap webspace...

if anyone finds anything please do post it

thnx!!

@t_yosuke817: As I know, NTT Docomo uses different Java specification than the rest of the world, so japanese applications won't work on your device. If I'm wrong, check the attributes in the jad file, that may tell not to run on your device. Where did you download from?

@kennykoksg: And don't forget, Java wallpaper is an application, not a static image. It can be interactive, or change dinamically, eg.: a virtual aquarium.

@MuGeNPoWeR: Delete the comma from the end of the url: http://www.jbenchmark.com

I can't transfer anything that was downloaded from FarEastone as the phone will not allow it.

I did not try the ktv function on my gx-21 simply because I rather go to a real karaoke place and sing. Besides, holding any phone and pretend it's a mic just seem ridiculous

I tried a Java wallpaper yesterday, but I don't know what is the big deal in this kind of application.
The phone (GX-20) recognise as a wallpaper application, but it acts, as any normal application. The name suggest, that it's a background (daemon) aplication, but the JVM stops the application, when an incoming call comes, or flip closed.

I know, that there is an interface, that must be implemented by a wallpaper midlet, but nothing usefull can be reached by this way. Did anybody find any wallpaper application (or its feature), that makes it differ from a normal application?

download java application (i-appli) from all sorts of place on the net... mostly in i-mode... juz dl to pc and then upload to wap web space thats all. just trying thats all... i never thought it iwll work but how will iknow if i dont try?

where did you get your java wallpaper from?

Posted by: kisember

I tried a Vodafone example application, that I put it on my site (temporarily, now avialable for a while): www.kisember.com/wa/le.jad

Where can I download any FREE allpication for GX-20 (or i-mode application). I didn't find any free GX-20 application that uses the qvga resolution. The phone magnifies the application by default and allow only 120x130px screen. There is a trick in the jad (or manifest) file, but the official Vodafone description isn't work for me. It allow to use 240x260 screen only in emulator, but not in real phone.
Could somebody explain me how can I use qvga resolution in my application, or guide me to any working demo?

Posted by: t_yosuke817

mmm i cant download the .jad file u post from my fone... am i even suppoised to download from my fone?

i do know there are some qvga java exists in japan for thoes with qvga display (for obvious reasons)... but i couldnt find any that could be downloaded

Hi Everyone,

The Java wallpaper on the GX22 etc. is really just a neat UI trick to allow Java apps to run as a screensaver. However, the app programmer has to identify the app as a screensaver in the JAD file. It is also possible for normal folks to hack JADs so that they become screensavers, but they might not completely work. Here's how to do it for a free app I found called Asteroid Zone that you can get from http://jfdoue.free.fr/

Note that this doesn't work for the GX20, only the GX22 and maybe other variants. There are other tags required for those that I think you can find on the Vodafone dev site (I'll try to post if I find them).

The original JAD file is:

Code:


MIDlet-1: AsteroidZone, icons/App.png, asteroids.Game
MIDlet-Jar-Size: 16048
MIDlet-Jar-URL: asteroids.jar
MIDlet-Name: Asteroids
MIDlet-Vendor: Jean-Francois Doue
MIDlet-Version: 1.4

If you edit in a text editor though to become:

Code:


MIDlet-1: AsteroidZone, icons/App.png, asteroids.Game
MIDlet-Jar-Size: 16048
MIDlet-Jar-URL: asteroids.jar
MIDlet-Name: Asteroids
MIDlet-Vendor: Jean-Francois Doue
MIDlet-Version: 1.4
MIDxlet-API: CJSP-1.0.0
MIDxlet-Resident: Y
MIDxlet-Drawing-Size: 240x260

Then you can turn it into a screen saver too. Also, that
MIDxlet-Drawing-Size makes it full screen QVGA! You can try this with a lot of free MIDP1.0 games or apps like Spruce Bowling etc. and see if it works. Sometimes they scale really well, other times they don't. Note that you HAVE to put the MIDxlet-API: CJSP-1.0.0 tag in there for the additional tags to work.

Once you have edited the JAD file you'll have to put the JAD and JAR files on a web site to download them to your phone. You might have to change the MIDlet-Jar-URL value to an explicit http://yourserver/asteroids.jar to make it point to the JAR to make it work, I'm not so sure about that part.

Hope this helps!

Almost clear.

I found that the Vodafone wallpaper example, that I tried use qvga resolution. The special atributes in jad are the followings:
MIDxlet-Network: N
MIDxlet-API: VSCL-1.0.1
MIDxlet-Resident: Y
MIDxlet-Application-Resolution: 120-240,130-320

So it seems, I have to specify MIDxlet-API attribute even if I don't use it (in contrast of the Vodafone doc, that tells nothing about using this attribute in this context).

I tried that with my application, and works! Hurray!!! I can port my applications to Sharp GX-2x devices.

The Vodafone devices (eg GX-20) use VSCL (Vodafone Service Class Library) that is a "J-phone clone". I don't know what is CJSP exactly, but I try to investigate.

This is why t_yosuke817 couldn't download the example.

ru sure the code for the gx22 is correct? coz it wont let me download after i edit the jad file....
