我支持使用 Jetty 9.0.6 和 JRE 1.7.0_45 的 Web 应用程序，并且该文件Jetty\webapps夹中的所有 war 文件都已成功部署。我遇到的唯一问题是webapps\root在 Jetty 启动期间我在日志文件中收到拒绝连接消息的文件夹。

该root文件夹包含一个非常基本的结构。

root/
root/index.html
root/WEB-INF/
root/WEB-INF/web.xml

基本上，根文件夹的目的是将查询重定向到根 (/) 到另一个路径。

此文件夹在 99% 的时间内成功部署在未受影响的服务器上。当它确实发生在特定服务器上时，它会始终如一地发生。成功的日志条目如下所示。

2014-06-26 18:05:36.408:INFO:oejsh.ContextHandler:main: Started o.e.j.w.WebAppContext@1347593{/,file:/C:/Program%20Files/MyApplication/Jetty/webapps/root/,AVAILABLE}{C:\Program Files\MyApplication\Jetty\webapps\root}

Jetty 在 Windows 服务器上运行。我在 Windows Server 2003 和 Windows Server 2008 R2 上看到过这个问题，但并不是在所有运行这些操作系统版本的服务器上都会发生。我检查了文件夹的文件夹权限，root并将它们与没有此问题的服务器进行了比较，没有区别。我还将root文件夹从没有问题的服务器复制到有问题的服务器，问题仍然存在。

任何人都可以建议可能导致这种情况发生的原因或在哪里进一步解决这个问题？

请记住，更改 Jetty 的版本不是我的选择，也不是更新 JRE。

当 jetty 解析 web.xml 并尝试下载 DTD 时，可能会发生这种情况。尝试从 xml 中删除 DTD，它可能看起来像这样：

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" >.

作为替代检查 URL 和 java 代理设置。
