在GlassFish中EJB应用程序部署失败

Question

我已经将2个项目添加为我的ejb项目的类库。这些cliass库项目只有SE Java类用于域和其他一些值对象。我使用GlassFish 3，IDE是Netbeans 7.0.1。所有类库项目，ejb项目和web项目（存在JSP和servlet）的任务'Clean & Builds'都是成功的，并且这个清洁& Build由IDE完成。但ejb项目无法部署，因为它提供了例外（java.lang.RuntimeException: java.lang.NoClassDefFoundError:），表示找不到类库。

我删除并多次添加这些库。但总是相同的错误。当我不使用这些类库并且不使用它们时，那​​么可以部署ejb应用程序。正如我的想法，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无法部署ejb应用程序（我不确切，但我猜）。

我是新来的ejb。请让我知道如何与其他项目一起部署这个ejb应用程序。在此先感谢
这里是错误。

您需要（例如，在WEB-INF/lib）你的战争中部署的外部lib或以某种方式将其放置在容器类路径中（不推荐）。如何做到这一点取决于你的容器和你的buildtool/ide。
