java - 在简单的 JXTA 2.7 应用程序中获取异常

Question

我正在 JXTA 2.7 中开发一个简单的程序，它向我显示以下错误。

public static void main(String[] args) throws IOException, PeerGroupException {
        System.setProperty(Logging.JXTA_LOGGING_PROPERTY, Level.OFF.toString());
        NetworkManager manager = new NetworkManager(NetworkManager.ConfigMode.EDGE, "Test");
        System.out.println(" S t a r t ing JXTA");
        manager.startNetwork();
        System.out.println(" JXTA St a r t ed ");            
}

错误:

......

我无法弄清楚这里出了什么问题。我已经下载了缺少的库 jetty并将其放入库路径(netbeans 7.0.1)。请大家帮帮我。

您需要将 netty 包含到您的类路径中。您可以从 netty.io 网站获取它。
