我使用Vaadin框架编写了我的第一个Web应用程序，现在我正尝试在线部署它。我将它导出到.war文件并在此处上传：http://www.eatj.com/但是在尝试运行时我收到有关安全性的错误。（项目名称 - JTPWebApp）

离线工作正常。我使用此代码

创建了文件server.policy和client.policy

grant  
{  
    permission java.security.AllPermission;  
};

但是我不知道在将它们放到哪里之后，在导出到.war文件后我看不到它们。对不起，如果这很简单，但我正在编写我的第一个网络应用程序而且我现在卡住了。

Answer 1

我强烈建议您尝试将第一个应用部署到OpenShift Redhat。这很简单，没有安全管理员也可以使用。
