【问题描述】：
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”任务都成功了，这个清理和构建由 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:）说找不到类库。
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。请告诉我如何将这个 ejb 应用程序与其他项目一起部署。提前感谢
这是错误。
