在openshift中运行项目后打开空白页

Question

我在openshift中部署了一个web应用程序。虽然构建和部署是成功的，但我在点击应用程序时得到了一个空白页面：

http://adoreindia-adoreindia.a3c1.starter-us-west-1.openshiftapps.com/

下面是pom.xml。

该应用程序在本地系统中运行良好。请建议我如何解决这个问题。

删除概要文件标记并更正上下文根、工件id，因为your-context-root-name解决了这个问题。

Answer 2

在构建日志中，查找.war文件的名称：

信息建设战争: /tmp/src/target/yourcontextrootname-0.0.1-SNAPSHOT.war

“您的上下文名称”是应用程序的上下文根--您应该看到您的上下文根名。(How to change context root of a dynamic web project in Eclipse?)

为了能够在OpenShift3启动程序中访问我的应用程序，我必须在.war文件的后面添加如下的名称
