JxtaServerSocket问题

Question

我正在使用 JxtaServerSocket （接收方）和 JxtaSocket （发送方）通过 LAN 传输文件。首先，我发送文件名而不是其大小。之后，我等待 offset 开始从中发送文件。如果我在本地（在一台计算机上）启动程序的两个部分，它可以正常工作，但如果在不同的计算机上，它就不起作用：

有一件有趣的事情，接收器获取文件名，但没有其他信息。 我想知道到底是什么原因导致这种奇怪的事情发生呢？ 另一方面，我想这可能是 JXTA 的错。

Answer 1

我与 Eugene 在 JXSE/JXTA 电子邮件列表上进行了讨论。他的堆栈跟踪之一似乎表明他在需要 TCP/HTTP 连接的场景中使用了 ADHOC 配置（仅使用多播）。我建议改用 EDGE / RDV 配置。从那以后我还没有收到反馈。我认为这解决了他的问题......
