您好，

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

JBoss 7.0 Runtime Server已经启动，我可以访问JBoss起始页http://localhost:8080和JBoss控制台。

我没有更改任何代码或xml，一切都是默认的。告诉我是否需要提供其他信息来调查此问题。

Answer 1

从错误中看，服务器上已经部署了“Hello world”（可能是您选择安装示例）：

Caused by: org.jboss.msc.service.DuplicateServiceException: Service jboss.naming.context.java.app.jboss-as-helloworld is already registered

尝试取消部署此应用，然后重新部署。或者您可以重命名您的第一个“hello world”应用程序并进行部署 - 因此没有名称冲突。

Answer 2

以下是我解决问题的步骤。

停止服务器。
转到部署路径。
手动删除部署文件夹中的现有项目。
重新启动服务器
再次部署应用程序。
