我有一個web應用程序。當我嘗試通過NetBeans中部署它，JBoss服務器引發以下錯誤：我應該如何解決JBoss中的java.lang.IllegalStateException「已經註冊」？
DEPLOYMENTS IN ERROR:
Deployment "vfs:///path/to/my/Application.ear" is in error due to the following reason(s): java.lang.IllegalStateException: Container jboss.j2ee:ear=Application.ear,jar=Application-ejb.jar,name=Another,service=EJB3,VMID=583c10bfdbd326ba:71d035f1:132a4c6a8ba:-7ffd + is already registered

我發現很多結果時，我google一下，所以這種錯誤似乎經常出現。但是我看到的所有結果都是論壇中的帖子，沒有顯示如何以一般方式解決問題。
問題似乎是應用程序已經在JBoss中註冊了。我在哪裏可以獲得已註冊的JBoss應用程序列表？我如何取消註冊一個應用程序（如果這可能有幫助）。
什麼是嘗試解決這類問題的好方法？
