我正在尝试评估是否可以升级到 jboss 7.1.1 我创建了我的 grails 应用程序的 war 文件：
grails war
然后我将战争文件放在 jboss 独立部署目录中。由于我在输出中看到，它似乎被服务器拾取：
11:43:19,026 INFO [org.jboss.as.server] (DeploymentScanner-threads - 2) JBAS018559: Deployed "my-application-0.1.war"
11:43:19,483 INFO [org.jboss.osgi.framework.internal.HostBundleState] (MSC service thread 1-4) Bundle started: my-application:0.1.0
但是，当我尝试访问 127.0.0.1/my-application 时，我收到 404 错误消息。关于发生了什么或如何调试此问题的任何想法？
更新：我刚刚在 jboss 日志中注意到了这个错误：
12:33:48,499 ERROR [org.jboss.as] (MSC service thread 1-2) JBAS015875: JBoss AS 7.1.1.Final "Brontes" started (with errors) in 4214ms - Started 151 of 227 services (1 services failed or missing dependencies, 74 services are passive or on-demand)
我发现另一个关于 grails 应用程序的 stackoverflow 问题没有与 jboss 一起运行，这与我面临的问题非常相似。我尝试了建议的解决方案并编辑了standalone.xml 文件。现在我面临一条实际的错误消息，在浏览器中我仍然收到 404 消息。这是来自 JBoss 日志的错误：
