Problems with selection

Please, give me working sample of selection!

My code is:

public void mouseClicked(MouseEvent e) {
	System.out.print(glEngine.doSelect(e.getPoint().x, e.getPoint().y));				
}

…

public int doSelect(int x, int y) {
float selectionRadius = 7f;
int hits;
int nearestNum;
float nearestRo;

	int[] selectBuf = new int[1024];
	
	int vp[] = new int[4];

	int width = camera.getWidth();
	int height = camera.getHeight();
            gl.glViewport(0, 0, width, height);
	gl.glGetIntegerv(GL.GL_VIEWPORT, vp);
	vp[0] = 0;
	vp[1] = 0;
	vp[2] = camera.getWidth();
	vp[3] = camera.getHeight();

	gl.glSelectBuffer(1024, selectBuf);
	gl.glRenderMode(GL.GL_SELECT);
	
	gl.glInitNames();
	gl.glPushName(0);

	gl.glMatrixMode(GL.GL_PROJECTION);
	gl.glLoadIdentity();
	glu.gluPickMatrix(x, camera.getHeight() - y, selectionRadius,
			selectionRadius, vp);
	camera.applyProjection();
	gl.glMatrixMode(GL.GL_MODELVIEW);
	gl.glLoadIdentity();
	camera.applyView();

	render(GL.GL_SELECT);
	
	gl.glFlush();

	hits = gl.glRenderMode(GL.GL_RENDER);

	...... // HITS ARE ALWAYS 0!!!
}
