Java 从命令提示符创建jar时出错

我试图创建一个jar文件。它应该包含一个连接到jdbc并检索结果的java主程序

我试图创建一个jar，jar创建成功，但在运行时出现了belw错误

  **java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver**

到底哪里出了问题？我是否正确地创建了jar？为什么找不到ojdbc6？

因为oracle驱动程序不在类路径上？Hi immibis。你能告诉我ojdbc6.jar将被放置在何处并将正确的命令发送到run吗？我知道我们可以将Classpath:header添加到mainfest文件中。因此，如果我想添加外部清单文件..jar创建命令是什么，Classpath:header的路径值应该是什么
