Hi,
你好，

我正在尝试启动 JBoss 示例应用程序“jboss-as-helloworld”。并得到了这样的例外：

JBoss 7.0 Runtime Server has started and I can access JBoss start page http://localhost:8080and JBoss console.
JBoss 7.0 运行时服务器已启动，我可以访问 JBoss 起始页http://localhost:8080和 JBoss 控制台。
I didn't change any code or xml, everything is default. Tell me if it is need to provide additional info to investigate this issue.
我没有更改任何代码或 xml，一切都是默认的。请告诉我是否需要提供其他信息来调查此问题。

From the error, it looks like "Hello world" already deployed on the server (perhaps you selected to install examples):
从错误来看，“Hello world”似乎已经部署在服务器上（也许您选择安装示例）：
Caused by: org.jboss.msc.service.DuplicateServiceException: Service jboss.naming.context.java.app.jboss-as-helloworld is already registered
Try undeploy this app and then deploy again. Or you could rename your first "hello world" app and deploy - so there is no name conflict.
尝试取消部署此应用程序，然后再次部署。或者您可以重命名您的第一个“hello world”应用程序并进行部署 - 这样就不会有名称冲突。

- Manually deleted the existing project in deployment folder.
- Restarted the server
- Deployed the application again.
