Java EJB:部署时注释处理出错

部署我的应用程序时，我收到一条警告“注释处理中出错：{0}”。后面是NoClassDefFoundError。它以前部署过，在我的应用程序开始发出这些警告和错误之前，我没有对它做任何更改

它突然启动，我甚至安装了新版本的Glassfish并重新安装了Netbeans。这种情况以前发生过，但重新启动IDE和Glassfish有助于解决此问题。（目录结构也保持不变）

我的应用程序结构如下： 应用 EJB（-Lib目录包含RemoteInterfaceLibrary.jar） WAR（-Lib目录包含EJB.jar和RemoteInterfaceLibrary.jar） 远程接口图书馆

感谢您的帮助。

EJB是否打包在战争中？您可以尝试单独部署ejb，然后部署WAR吗？

当我从project（右键单击project）>properties>run中选择不同的Glassfish 4.0服务器配置时，它似乎神奇地重新开始工作（一次部署整个应用程序）。

ejb.jar位于WAR lib文件夹中。EJB部署很好，但在部署war时，我得到了以下结果：“异常描述：PersistenceUnit[xxx ejbPU]的预部署失败。”第二次尝试时，我得到了以下结果：“java.lang.RuntimeException:绑定JNDI名称bean时出错。UserListRemote for EJB UserListBean”
