java httpexchange对jquery的响应ajax调用为空

I'm using ajax to do a post to a java program I've written (that implements com.sun.net.httpserver.httphandler). I've got a problem that I can do the ajax call and see it get caught in the java program, however in Firebug, the response is empty.

我正在使用ajax对我编写的java程序（实现com.sun.net.httpserver.httphandler）发帖。我有一个问题，我可以执行ajax调用，看到它被java程序捕获，但在Firebug中，响应为空。

Here is my ajax code.

这是我的ajax代码。

jQuery.ajax({
    type: "POST",
    url: "http://localhost/applications/nvn",
    data: "command=GetNVN",
    dataType:"text",
    success: function(msg){
    var fdsa;
    fdsa++;
    init(msg);
    },
    error: function( foo ){
    var fff;
    fff++;
    }
});

And here is my server code.

这是我的服务器代码。

    Headers headers = t.getRequestHeaders();
    Set<Map.Entry<String, List<String>>> entries = headers.entrySet();

    StringBuffer response = new StringBuffer();
    for (Map.Entry<String, List<String>> entry : entries)
      response.append(entry.toString() + "\n");

    t.sendResponseHeaders(200, response.length());
    OutputStream os = t.getResponseBody();
    os.write(response.toString().getBytes());
    os.close();

The error handler in the jQuery code has an object that says "error" in it. One additional detail, my server is on port 80 so as far as I know, there is no cross domain querying going on... I think.

jQuery代码中的错误处理程序有一个对象，其中包含“错误”。另外一个细节，我的服务器在端口80上，据我所知，没有跨域查询...我想。

Any suggestions are appreciated,

I figured it out.

我想到了。

I was making a cross domain ajax call. I just changed the content-type to jsonp and it worked.

我正在进行跨域ajax调用。我刚刚将内容类型更改为jsonp并且它有效。
