下面是后台action
@Action(value="copyBook",results={@Result(type="stream",params={"inputname","inputStream"})})
public String copyBookInfo()
{
HttpServletResponse response = ServletActionContext.getResponse();
HttpServletRequest request = ServletActionContext.getRequest();
response.setCharacterEncoding("UTF-8");
ByteArrayOutputStream output = new ByteArrayOutputStream();
String info="";
try
{
setBookId(Integer.parseInt(request.getParameter("bookId")));
planeCopyUtil.copyBook(bookId);
info="成功";
output.write(info.getBytes("UTF-8"));
inputStream=new ByteArrayInputStream(output.toByteArray());
output.close();
}
catch(Exception e)
{
e.printStackTrace();
}
return SUCCESS;
}
这是前台
function copy(){
var bookId = llbId();
$.ajax({
type: 'post',
dataType:"text",
data:{"bookId":bookId},
url: '/AirRecord3/copyBook',
cache: false,
success: function (data) {
alert(1);
},
error: function (msg) {
alert("异常"+msg);
}
});
}
出现这样的错误

表示我是初学者求大神指教

你的ajax进入到后台了么？ 执行过程怎么样
