我第一次使用Java EE，我能够获得一个hello world应用程序，可以同时使用调用ejb的Web客户端和控制台客户端。
在我确认代码正常工作后，我添加了一个使用logback进行日志记录的记录器。一旦我在我的代码中添加了记录器，我就会收到以下错误，如果我删除了logback，则错误就会消失。
有没有办法在EJB上运行logback？

显然是：The logback demo page列出了一个包含Web应用程序的示例。

作为旁注：唯一失败的部署是web，客户端控制台应用程序正常工作。
我收到错误：

Error occurred during deployment: Exception while preparing the app : Unable to load the EJB module. DeploymentContext does not contain any EJB. Check the archive to ensure correct packaging for C:\Users\roberth\Programming_Projects\NetBeans\WebInterface\build\web.
If you use EJB component annotations to define the EJB, and an ejb or web deployment descriptor is also used, please make sure that the deployment descriptor references a Java EE 5 or higher version schema, and that the metadata-complete attribute is not set to true, so the component annotations can be processed as expected.
