hi all, here is my problem, i hope someone can help me :
here is the code i use before using the gluUnProject method : 

int[] viewport=new int[4]; 
gl.glGetIntegerv(gl.GL_VIEWPORT,viewport); 
double[] proj=new double[16]; 
gl.glGetDoublev(gl.GL_PROJECTION_MATRIX,proj); 
double[] model=new double[16]; 
gl.glGetDoublev(gl.GL_MODELVIEW_MATRIX,model); 

but after this my tables are still filled with '0'
