Question

我有一个简单的servlet应用程序。我创建了war文件并在我的本地服务器上尝试过 - 一切顺利。然后我决定在openshift服务器上发布它。

这是链接http://asciiart-pbweb.rhcloud.com/ 我按照这些说明将我的war文件重命名为ROOT.war

https://developers.openshift.com/servers/tomcat/deployment-options.html 并将所有内容推送到服务器。

但是现在它变成了503错误。我无法弄清楚出了什么问题。

我输入了这个命令

 rhc tail asciiart

以及

的完整输出
