    m3g file creator

    hi, I'm tring to build a "m3g file creator" program that will
    dynamaicly build a m3g file in the server_side and then pass
    the file to a mobile client (the reason why I can't just use a grathics
    program like for example - blender is beacouse I don't know in advance
    the world I need to create, that is the data of the worls is dynamic and
    changes from time to time).

    after creating the m3g file the client will use the loader class (from the jsr-184)
    to load the world.

    I started building the program and acording to the m3g format I build a file
    with an empty world (just to see if I can load it).

    when I tried to load the file I got this exeption:
    java.io.IOException: no ':' in URL
    at javax.microedition.m3g.Loader.loadHelper(+375)
    at javax.microedition.m3g.Loader.load(+17)
    at test4.M3GCanvas5.createSceneGraph(M3GCanvas5.java:68)
    at test4.M3GCanvas5.<init>(M3GCanvas5.java:38)
    at test4.RotateLineMidlet.<init>(RotateLineMidlet.java:10)
    at java.lang.Class.runCustomCode(+0)
    at com.sun.midp.midlet.MIDletState.createMIDlet(+34)
    at com.sun.midp.midlet.Selector.run(Selector.java:151)

    does anyone know of a source code / or a jar file that does what I'm tring to do

    does anyone know where I can find the source code of the loader class, so that I can
    see what the problem is.

    I would be glad for any help...

    Re: m3g file creator

    I assume the blender m3g exporter is open source, so you could have a look at that.
    You can download the phoneme source code from sun, but not sure if they open sourced the 3d stuff
