I am using Thomas' Game sample and his JPCT extentions (Both are Great Help ! Thanks for open sourcing them !!! ) for creating a world with a cuboid and a plane surface which is having a spotlight.
I really know nothing about shaders, but at the same time trying/eager to have some basic shadowsmapping in my work . 
What I did -
1. On My Oncreate Method I loaded custom shaders .
ZipInputStream zis = new ZipInputStream(res.openRawResource(R.raw.data));
ZipEntry ze;
try {
while ((ze = zis.getNextEntry()) != null) {
BLABLA....

ShaderProvider.setShader(ze.getName(), sb.toString());
}

zis.closeEntry();
zis.close();
          BLABLAh....
2. On my OnSrfacechanged...
shadowHelper = new cz.chladek.jpct.extension.ShadowProjector();
world.getLightController().setShadowHelper(shadowHelper);

3.Ondrawfrme::..
shadowHelper.update(world, fb);


4.  Removed               world.renderScene(fb);
world.draw(fb);

fb.display(); This from my ondrawframe.


Also THis is what in the update method..............
public void update(World world, FrameBuffer fb) {
if (light != null) {
if (!setted) {
Enumeration<Object3D> objects = world.getObjects();
while (objects.hasMoreElements()) {
Object3D object = objects.nextElement();
if (!object.getName().startsWith("particle")) {
PolygonManager pm = object.getPolygonManager();
int maxID = pm.getMaxPolygonID();
for (int i = 0; i < maxID; i++)
pm.addTexture(i, textureID, TextureInfo.MODE_MODULATE);
}
}
projectionMatrix = projector.getProjectionMatrix(fb, nearPlane, farPlane);
setted = true;
}
updateProjector();
Camera originalCam = world.getCamera();

world.setCameraTo(projector);
fb.setRenderTarget(shadowTexture, 1, 1, 1, 1, true);
fb.clear(RGBColor.WHITE);
Tools.renderWithShader(world, fb, depthShader);
fb.display();
fb.removeRenderTarget();
world.setCameraTo(originalCam);
}
}

And Tools.renderwithshader......................
public static void renderWithShader(World world, FrameBuffer fb, GLSLShader shader) {
Enumeration<Object3D> objects = world.getObjects();
while (objects.hasMoreElements()) {
Object3D obj = (Object3D) objects.nextElement();
if (obj.getVisibility()) {
GLSLShader objShader = obj.getShader();
shaders.add(objShader);
obj.setShader(shader);
}
}

world.renderScene(fb);
world.draw(fb);

objects = world.getObjects();
int i = 0;
while (objects.hasMoreElements()) {
Object3D obj = (Object3D) objects.nextElement();
if (obj.getVisibility()) {
GLSLShader objShader = shaders.get(i);
obj.setShader(objShader);
i++;
}
}
shaders.clear();
}


**********************************************************************
  ___ Result was a blank black screen .___...I also used this
shadowHelper.blitShadowMap(fb, halfW - 64, fb.getHeight() - size - 10, size);
to blit the shadowTexture ... but it is also blank white blit .

Then I did many funny experiments with different laughable  results but none produced the desired results.

also my log o/p is full of this-
02-27 10:59:17.330: I/jPCT-AE(7147): Additional visibility list (106) created with size: 512
02-27 10:59:17.350: I/jPCT-AE(7147): Additional visibility list (107) created with size: 512

  I am making a blender script which exports a text file which is readable in jbrush ,which I can load in android. But I am bit confused because of wrong positioning of objects in exported scene files.
for example -- I have 2 3d objects in blender and set both of their positions to different co-ords and export them  . But when I load them in jbrush/device , and set both their  translation to (0,0,0), then I want that both objects should coincide . But they are not coinciding  . I want some suggestions to correct my code for positioning  of objects please help!

   I wanted to reduce the loading  time . Is that possible ? I mean , once the data is in the disk , I don't want it to be re-written . Is there is a way to check that ?

      I have a .3ds model (a simple box used as a crate ) which is deformed .It simply double in height halved in width. This never happened before. Everything is running fine ....i.e no error. I'm using jbrush for scene loading.

Hello!

    I have a problem in rotating my 3d box object in proportional to the jbox2d physics engine's box rotation. The rotation and translation of the physics shape is correct and my 3d box's translation are correct.But I'm messing with the rotation of my 3d box along its axis. It keeps rotating even if the rotation of the physics object has stopped and even rotates unrealistically fast or slow any time. I have never used a physics engine  before so maybe I am doing it in the wrong way. Can anybody tell me how to make it proportional.
