Java获取上传POST文件

Question

我正在开发一个项目，可以将文件从本地PC网络浏览器（Chrome或IE）上传到手机网络服务器。

我有些如何设法将文件上传到服务器，代码就像这样

$.ajax({
        url: loc,
        type: "POST",
        data: formdata,
        processData: false,
        contentType: false,
        success: function (res) 
        {
                $.prompt("File uploaded", 
            {
                buttons : 
                {
                    "OK" : true
                },
                callback : refreshFileCallback
            }); 
        }
    });

如何在java中通过POST发送上传的文件？

            httpService.setParams(params);

            HttpRequestHandlerRegistry reqistry = new HttpRequestHandlerRegistry();

            reqistry.register("*" + SUFFIX_ZIP, new HttpZipHandler(webRoot));

            reqistry.register("*", new HttpFileHandler(webRoot));

            httpService.setHandlerResolver(reqistry);

            isLoop = true;
            while (isLoop && !Thread.interrupted()) 
            {
                Socket socket = serverSocket.accept();
                DefaultHttpServerConnection conn = new DefaultHttpServerConnection();
                conn.bind(socket, params);
                Thread t = new WorkerThread(httpService, conn);
                t.setDaemon(true);
                t.start();
            }
        } 
        catch (IOException e) 
        {
            isLoop = false;
            e.printStackTrace();
        } 
        finally 
        {
            try 
            {
                if (serverSocket != null) 
                {
                    serverSocket.close();
                }
            }
            catch (IOException e)
            {
            }
        }
    }

    public void close() 
    {
        isLoop = false;
    }

}

如果不可能，请建议我另一种方法，如何将文件从HTML上传到java
