import - Issue with Standalone in Processing -

-

i have sketch running in processing 2.1.2, , runs fine sketch window. when try export standalone windows application, processing creates application.windows folder, contains 'lib' , 'source' subdirectories. when double-click application, showing me blank window.

can guide me on how resolve issue? coding of program given below:

import toxi.geom.*; import toxi.geom.mesh.*; import toxi.processing.*; import processing.serial.*; trianglemesh mesh; toxiclibssupport gfx; pimage img; string input; serial port; int x,y,z; void setup() {   size(448, 299,p3d);   println(serial.list());   port = new serial(this,serial.list()[0], 9600);   port.bufferuntil('\n');   mesh=(trianglemesh)new stlreader().loadbinary(sketchpath("check.stl"),stlreader.trianglemesh);   gfx=new toxiclibssupport(this);   img=loadimage("imagei.jpg"); } void draw() {   background(img);   translate(width/2,height/2,0);   rotatex(radians(x));     // pitch   rotatey(radians(y));    // roll   rotatez(radians(z));   // yaw   directionallight(192, 168, 128,0, -1000, -0.5);   directionallight(255, 64, 0, 0.5f, -0.5f, -0.1f);   nostroke();   scale(2);     gfx.mesh(mesh,false); } void serialevent(serial port) {  input = port.readstring();  if(input != null) {    string[] values = split(input, " ");    println(values[0]);    println(values[1]);    println(values[2]);    x= int(values[0]);y= int(values[1]);z= int(values[2]);  }  }

edit line of program:

mesh=(trianglemesh)new stlreader().loadbinary(sketchpath("check.stl"),stlreader.trianglemesh);

by:

mesh=(trianglemesh)new stlreader().loadbinary(sketchpath("data/check.stl"),stlreader.trianglemesh);

and rest of program fine, check , let me know if error.
