public class HelloSpark {
  public static void main(String[] args) {

        String splats[] = request.splat();
        String str = "Number of splat parameters: " + request.splat().length;
        str = str + "<br /> splat parameters are ";
        
        for(String s : splats){
          str = str + s + "  ";
        }
