我已将 2 个项目作为类库添加到我的 ejb 项目中。这些 cliass 库项目只有 SE Java 类，它们用于域和一些其他值对象。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，此清理和构建由 IDE 完成。但是无法部署 ejb 项目，因为它给出了异常（java.lang.RuntimeException: java.lang.NoClassDefFoundError:）表示找不到类库。

我多次删除并添加了这些库。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，可以部署 ejb 应用程序。我认为，问题是，如果任何其他项目已导入并添加到 ejb 应用程序中，IDE 将无法部署 ejb 应用程序。（我不确切知道，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。在此先感谢
这是错误。

您需要在您的战争中部署您的外部库（例如 in WEB-INF/lib）或以某种方式将其放置在容器类路径中（不是首选）。如何做到这一点取决于您的容器和您的构建工具/IDE。
