原谅我，但我对此很陌生。我的工作计算机上有一个 JNLP 文件，并且可以在家工作。我设置了我的 VPN，并将 JNLP 文件复制/粘贴到我的家用计算机上。但是，当我启动它（我使用 Windows 7 Home Premium 升级到 Java 7）时，我遇到了无法启动应用程序的问题。

它显示无法加载资源，然后

com.sun.deploy.net.FailedDownloadException: Unable to load resource: http: //pbs-sj1/pbs/jnlp/tnp/msgr/alt.jnlp
    at com.sun.deploy.net.DownloadEngine.actionDownload(Unknown Source)

这是在包裹部分下

我在网上做了很多研究，但老实说，大部分似乎都是在开发人员层面。我只是想让 JNLP 文件启动。

有任何想法吗？

错误消息告诉您它无法确定您要访问的主机：

java.net.UnknownHostException: pbs-sj1

可能最简单的做法是在您拥有此 .jnlp 文件的盒子上编辑您的主机文件并添加：

127.0.0.1 pbs-sj1

然后确保您的实际 .jnlp 文件位置与您指定的其余路径 (/pbs/jnlp/tnp/msgr/alt.jnlp) 对齐。这是在Win7上编辑主机文件的方法。

-或者-

与其弄乱 Hosts 文件，不如使用文件 URL 来指定在 Windows 上找到 .JNLP 文件的位置——例如，

file:///C:/Documents%20and%20Settings/your_login/alt.jnlp

（我假设您知道将这些地址中的任何一个粘贴/键入到启用 Java 的浏览器的地址栏中）
