我在 TomEE 服务器上使用 OpenJPA。

我构建了我的 .war，将其部署在服务器上，但是当我使用我的应用程序打开页面时，我得到了这个 execption：

javax.servlet.ServletException: WebBeans context with scope type annotation @RequestScoped does not exist within current thread
  javax.faces.webapp.FacesServlet.service(FacesServlet.java:229)
  filters.NoCacheFilter.doFilter(NoCacheFilter.java:42)

  com.ocpsoft.pretty.PrettyFilter.doFilter(PrettyFilter.java:145)

好的，我发现问题出在哪里。

首先，我必须阅读启动我的 TomEE 服务器的日志。我在那里发现，我的一个 EJB 类有问题。我用事务管理器注入资源：

   @Resource
   private UserTransaction userTransaction;

但我忘记通过以下方式注释我的服务 EJB：

@Stateless
@TransactionManagement(TransactionManagementType.BEAN)
public class TaskService {
  ...
}

如果“某人”不加批判地删除了应用程序的登录页面，也可能会发生这种情况。
