在GlassFish中EJB應用程序部署失敗

Question

我在我的ejb項目中添加了2個項目作為類庫。 這些氣候庫項目只有SE Java類，它們用於域和其他一些值對象。 我使用GlassFish 3，IDE是Netbeans 7.0.1。 所有類庫項目，ejb項目和Web項目（包含JSP和servlet的項目）的“清理和構建”任務均成功完成，並且清理和構建由IDE完成。 但是ejb項目無法部署，因為它會給出異常（ java.lang.RuntimeException: java.lang.NoClassDefFoundError: ：），提示未找到類庫。

我多次刪除並添加了這些庫。 但是總是相同的錯誤。 當我不使用這些類庫並且不使用它們時，可以部署ejb應用程序。 我認為問題是，如果導入了任何其他項目並將其添加到ejb應用程序中，則IDE無法部署ejb應用程序（我不知道，但我想確切）。

我是ejb的新手。請讓我知道如何與其他項目一起部署此ejb應用程序。 提前致謝
這是錯誤。

您需要在戰爭中部署外部庫（例如，在WEB-INF/lib ）或以某種方式將其放置在容器類路徑中（不推薦使用）。 如何執行此操作取決於您的容器和您的buildtool / ide。
