java - 尝试注册 XMPP

Question

我正在尝试创建一个帐户，然后登录到我的 XMPP 服务器。

我已经走到这一步了:

                try {
                    System.out.println("trying to register for XMPP");
                    XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
                            .setServiceName("jabber.org")
                            .setHost(AppConfig.XMPP_HOST)
                            .setPort(Integer.parseInt(AppConfig.XMPP_PORT))
                            .build();

                    XMPPTCPConnection connection = new XMPPTCPConnection(config);
                    connection.connect();
                    AccountManager accountManager = AccountManager.getInstance(connection);

                    accountManager.createAccount(name, password);

                    connection.login(name, password);

                } catch (Throwable e) {
                    e.printStackTrace();
                }

这是输出:

错误发生在

connection.connect();

我在 linux 上使用 Ejabberd。

日志显示已成功建立连接，所以我真的不知道出了什么问题。

可能是什么问题？

首先你需要检查服务器是否支持In-Band Registration .据我所知，在 jabber.org 上的公共(public)注册是 disabled许久。
