texture coordinate - uv mapping

Hi,

I have a little problem with the collada export 1.4 on Blender.

I simply textured a cube with an image *.jpg (like the attach file).
I exported this cude textured and I get this result:


	<library_images>
		<image id="Paper0029_2_thumblarg-img" name="Paper0029_2_thumblarg-img">
			<init_from>/Users/....../Desktop/Paper0029_2_thumblarge.jpg</init_from>
		</image>
	</library_images>
       .......
	<library_geometries>
		<geometry id="Cube_001" name="Cube_001">
			<mesh>
				<source id="Cube_001-Position">
					<float_array count="24" id="Cube_001-Position-array">
						..........
                                       </float_array>
					<technique_common>
						.........
					</technique_common>
				</source>
				<source id="Cube_001-Normals">
					<float_array count="18" id="Cube_001-Normals-array">
                                                ..........
                                        </float_array>
					<technique_common>
                                                ..........						
					</technique_common>
				</source>
				<vertices id="Cube_001-Vertex">
					<input semantic="POSITION" source="#Cube_001-Position"/>
				</vertices>
				<triangles count="12" material="Material">
					<input offset="0" semantic="VERTEX" source="#Cube_001-Vertex"/>
					<input offset="1" semantic="NORMAL" source="#Cube_001-Normals"/>
					

0 0 1 0 2 0 2 0 3 0 0 0 4 1 7 1 6 1 6 1 5 1 4 1 0 2 4 2 5 2 5 2 1 2 0 2 1 3 5 3 6 3 6 3 2 3 1 3 2 4 6 4 7 4 7 4 3 4 2 4 4 5 0 5 3 5 3 5 7 5 4 5</p>
				</triangles>
			</mesh>
		</geometry>

I don’t understand why the texture coordinates don’t appear.

I try to export another example more complex and I get easily the xml part about the uv mapping coordinates


<source id="Cylinder_001-UV">
	<float_array count="2280" id="Cylinder_001-UV-array">
                  .....
         </float_array>
	<technique_common>
                  .....
	</technique_common>
</source>

How do I hnow how the cube is mapped in my first example?
Is it normal the coordinates don’t appear in this first example?

Tks
