openfire smack发送包404错误意味着什么？

Question

当使用Smack将数据包发送到openfire时,我得到错误remote-server-not-found(404).任何人都可以解释这个错误意味着什么？它意味着无法连接到服务器或数据包有问题？

        PacketFilter responseFilter = new PacketIDFilter(packet.getPacketID());
        PacketCollector response = connection.createPacketCollector(responseFilter);

        connection.sendPacket(packet);



        // Wait up to a certain number of seconds for a reply.
        Packet result = response.nextResult(timeout);



        // Stop queuing results
        response.cancel();



        if (result == null) {
            throw new XMPPException("No response from server.");
        }
        else if (result.getError() != null) {  

            System.out.println("error:"+result.getError());   //i get error here.... 404
            throw new XMPPException(result.getError());
        }

// ---下面是我如何连接到openfire.

        ConnectionConfiguration config = new ConnectionConfiguration("localhost", 5222);
        config.setCompressionEnabled(true);
        config.setSASLAuthenticationEnabled(true);



        XMPPConnection connection = new XMPPConnection(config);
        // Connect to the server
        connection.connect();
        // Log into the server
        connection.login("test", "test","testresource");

我附上了从日志中收到的xmpp xml

我遇到了一个类似的问题,我刚刚解决了.

我在本地计算机上运行了一个Openfire服务器,我正在使用Smack API与服务器通信.在Openfire中,我定义了两个用户:发送者和接收者.我没有使用电子邮件地址作为用户名.

在我的代码中,我在一个线程上有一个"sender"连接,在一个单独的线程上有一个"receiver"连接.最初,在发送消息时,我收到了remote-server-not-found(404)来自Openfire服务器的错误响应.我发现,当发件人创建聊天请求时,我需要将参与者设置为receiver@[Openfire domain].

因此,如果您的Openfire域名是foo,那就是receiver@foo.显然,这不是"接收者"用户的电子邮件地址.通常,域实际上只是运行Openfire服务器的计算机的名称.
