Java 在glassfish中找不到ejb类？

我有一个JavaEE应用程序，我正试图从servelate调用EJB，但每次我都会遇到这个错误

HTTP Status 404 - Not Found

type Status report

messageNot Found

descriptionThe requested resource is not available.

我查了一下玻璃鱼日志我看到了

来自EJB文档（）：

名称-指定要在环境中查找引用EJB的名称

您使用的是（name=“sfm”），这意味着容器将查找它所知道的名为“sfm”的bean，这在您的例子中是错误的，除非您在beans.xml中定义了bean名称（但您没有提到它，所以我假设您没有提到）

---

只需删除（name=“sfm）部分，不要忘记重新部署应用程序。

仍然找不到严重的：Class[Lejbexercises/StatlessFundManagerBean；]。加载[Class controllers.TestStatelessEJB]时出错您能否在EJB初始化的位置重新部署应用程序和服务器后日志行。这可能是部署问题。您如何尝试访问网页？我刚刚复制了您的示例。一切正常（没有name=“sfm”）.仔细看，我注意到您的第一个问题是根本无法访问servlet。请确保在浏览器中键入正确的地址。这就是我想问的问题？您的项目是否位于我的doc\netbeansProjects中？不，我使用的是Eclipse
