i found this, it looks like it is going to work

String str = "testing";
  byte[] outBytes = str.getBytes();
  response.setContentType ("application/x-msexcel");
  response.setContentLength(outBytes.length);
  
  response.setHeader ("Content-Disposition", "inline;filename=\"ComputeOrder.csv\""); 

  byte[] buf = outBytes;
  int length = 0;
  ServletOutputStream op = response.getOutputStream ();
  op.write(buf,0,buf.length);
  op.close();
