GWT应用程序获取“404请求的资源不可用”
问题描述：
我不知道为什么当我访问我的GWT应用程序时，我总是收到“404请求的资源不可用”。我目前正在我的TomEE/8.5.6（7.0.2）上托管我的GWT应用程序。GWT应用程序获取“404请求的资源不可用”
这是情况。
我能够用我的GWT应用程序从 “TomEE Web应用程序管理器” 为（HTTP）：//192.168.1.70：8080 /指数
但是，当我输入（HTTP）： //www.zethanath.tk在浏览器中，我会得到（HTTPS）：//www.zethanath.tk/与HTTP状态404
这里是我的配置的细节。

我一直在想，我需要端口8080 “的DocumentRoot” 关联/ opt/tomcat/webapps/Index“，但我不确定如何。
这是我的UFW的细节。路由器。

非常感谢帮助。

Uoo，你真的不应该使用DocumentRoot，否则你会暴露整个战争。
您更好地使用mod_proxy的重定向请求到Tomcat的HTTP端口：
ProxyPass/http://localhost:8080/
ProxyPassReverse/http://localhost:8080/
或者，如果你想重定向到Tomcat上下文（前 '索引'。）：
ProxyPass/http://localhost:8080/Index/ retry=1
ProxyPassReverse/http://localhost:8080/Index/
Header edit Location ^([^/]*//[^/]*)?/Index/(.*)$ $1/$2
ProxyPassReverseCookiePath /Index/

非常感谢您的回复。这是我的/opt/tomcat/conf/web.xml的内容。请注意，我的GWT应用程序存储在/ opt/tomcat/wepapps /中，名称为Index.war，所以我一直在想我可能不需要在最后配置“welcome-file-list”。

如果你不知道什么我的意思是“暴露整个战争”刚刚打开http：//localhost/WEB-INF/web.xml与当前的配置。 –
非常感谢您的回复。另外，有什么办法可以坚持Mod JK？我听说Mod JK更好，所以我从Mod Proxy切换到Mod JK。我不能再切换回来:) – sethanath
另请注意，我在http虚拟主机的末端执行了Mod_rewrite。这篇文章会将用户重定向到SSL vhost，SSL vhost会使用Mod JK将用户重定向到GWT应用程序。 – sethanath
