Question

我正在构建一个使用javax.smartcardio库的Karaf OSGI应用程序。当我部署它时，它给了我以下错误：

我想将javax.smartcardio库打包为一个包。有关于如何从.jar构建包的链接，但我在JDK中找不到javax.smartcardio库。

它在JDK中吗？我是否必须做任何特殊的事情才能访问它。谢谢。

Answer 1

如果它是JDK的一部分，请确保将其导出为系统包。为此编辑 etc / jre.properties 文件。

您需要将相应的包添加到您使用的JVM部分。通常，如果已知，最好以正确的版本导出它。

将javax.smartcardio打包为OSGI Bundle
