在java类中用js实现跳转页面

try{	
    //通过设置，防止js中文乱码
    response.reset();   
    request.setCharacterEncoding("GBK");
    response.setContentType("text/html; charset=GBK");
    ServletOutputStream servletOutputStream  = response.getOutputStream();
    String s = "咨询成功！";
    //用js实现转页
    servletOutputStream.println("<script language='JavaScript'>alert('"+s+"')         </script>");
    servletOutputStream.println("<script language=javascript>window.location.href=\"/satQuestionAction.do?method=qtAdd\"</script>");
			
  }catch (Exception e) {
}
