嗨，

我正在尝试启动 JBoss 示例应用程序“jboss-as-helloworld”。 并得到这样的异常(exception):

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额外信息来调查此问题。

最佳答案

从错误来看，“Hello world”似乎已经部署在服务器上(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 - 这样就不会发生名称冲突。

关于java - JBoss HelloWorld 应用程序未启动，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/15765651/
