java - GlassFish 中的 EJB 应用程序部署失败

Question

我已将 2 个项目作为类库添加到我的 ejb 项目中。这些 cliass 库项目仅包含用于域和其他一些值对象的 SE Java 类。我使用 GlassFish 3，IDE 是 Netbeans 7.0.1。所有类库项目、ejb 项目和 Web 项目(其中存在 JSP 和 servlet)的“清理和构建”任务均成功，并且此清理和构建由 IDE 完成。但是ejb项目无法部署，因为它给出异常(java.lang.RuntimeException: java.lang.NoClassDefFoundError:)，表示未找到类库。

我多次删除和添加这些库。但总是同样的错误。当我不使用那些类库并且不使用它们时，那​​么就可以部署ejb应用程序。我认为，问题是，如果已导入任何其他项目并将其添加到 ejb 应用程序，则 IDE 无法部署 ejb 应用程序。(我不太清楚，但我猜)。

我是 ejb 新手。请让我知道如何将此 ejb 应用程序与其他项目一起部署。提前致谢
这是错误。

您需要在您的 war 中部署外部库(例如在WEB-INF/lib中)或以某种方式将其放置在容器类路径中(不推荐)。如何执行此操作取决于您的容器和构建工具/IDE。
