newbie problem with textures...

i am doing some little 3-d maps for the documentation of the spatial configuration of scene elements in a theatrelab here in copenhagen.
wanting to learn processing i am using this task as a way to get started...
but i cannot make texturing compute in my code.
i.e. in other code, such as the examples in posted online elswhere on this site texturing works, even if i use my own .jpg that i cannot see in my own code.
so i hope that some of you guys can lead me on the way by looking through my code below as i figure i must have done _something_ wrong:
BImage a;
float xmag, ymag = 0;
float newXmag, newYmag = 0;
void setup()
{
size(400, 300);
noStroke();
colorMode(RGB, 1);
//skal være 200*200 jpg
a = loadImage("gulv.jpg");
}
void loop()
{
background(1,1,1);
push();
translate(width/2, (height/2)+40, -50);
newXmag = mouseX/float(width) * TWO_PI;
newYmag = mouseY/float(height) * TWO_PI;
float diff = xmag-newXmag;
if (abs(diff) > 0.01) { xmag -= diff/4.0; }
diff = ymag-newYmag;
if (abs(diff) > 0.01) { ymag -= diff/4.0; }
//rotateX(-ymag);
rotateY(-xmag);
//scale(ymag);
scale(4);
//GULV
beginShape(QUADS);
texture(a);
vertex(30,0,-30, 0,0);
vertex(30,0,30, 0,200);
vertex(-30,0,30, 200,0);
vertex(-30,0,-30, 200,200);
endShape();
//RAMME
push();
scale(1.5);
rotateY(0.5);
beginShape(QUADS);
fill(0.1, 0.1, 0.1);
//front
vertex(0, 0, 0);
vertex(1.5, 0, 0);
vertex(1.5, -10, 0);
vertex(0, -10, 0);
vertex(1.5, -8.5, 0);
vertex(8.5, -8.5, 0);
vertex(8.5, -10, 0);
vertex(1.5, -10, 0);
vertex(8.5, 0, 0);
vertex(10, 0, 0);
vertex(10, -10, 0);
vertex(8.5, -10, 0);
vertex(1.5, -1.5, 0);
vertex(8.5, -1.5, 0);
vertex(8.5, 0, 0);
vertex(1.5, 0, 0);
//bagside
vertex(0, 0, -1.5);
vertex(1.5, 0, -1.5);
vertex(1.5, -10, -1.5);
vertex(0, -10, -1.5);
vertex(1.5, -8.5, -1.5);
vertex(8.5, -8.5, -1.5);
vertex(8.5, -10, -1.5);
vertex(1.5, -10, -1.5);
vertex(8.5, 0, -1.5);
vertex(10, 0, -1.5);
vertex(10, -10, -1.5);
vertex(8.5, -10, -1.5);
vertex(1.5, -1.5, -1.5);
vertex(8.5, -1.5, -1.5);
vertex(8.5, 0, -1.5);
vertex(1.5, 0, -1.5);
//inderside
vertex(1.5, -1.5, -1.5);
vertex(1.5, -8.5, -1.5);
vertex(1.5, -8.5, 0);
vertex(1.5, -1.5, 0);
vertex(1.5, -1.5, -1.5);
vertex(8.5, -1.5, -1.5);
vertex(8.5, -1.5, 0);
vertex(1.5, -1.5, 0);
vertex(8.5, -1.5, -1.5);
vertex(8.5, -8.5, -1.5);
vertex(8.5, -8.5, 0);
vertex(8.5, -1.5, 0);
vertex(1.5, -8.5, -1.5);
vertex(8.5, -8.5, -1.5);
vertex(8.5, -8.5, 0);
vertex(1.5, -8.5, 0);
endShape();
pop();
pop();
