原文 2015-01-02 17:39:17 5 1 java/ eclipse/ jdbc/ jar

I have implemented simple Swing application which creates database and added mysql-connector-java-5.1.18-bin.jar to my projects build path. 我已经实现了简单的Swing应用程序，它创建数据库并将mysql-connector-java-5.1.18-bin.jar添加到我的项目构建路径中。 it works fine when I run in Eclipse as a project. 当我在Eclipse中作为项目运行时，它工作正常。 But I exported this project to runnable jar file it doesnt work. 但我将此项目导出到runnable jar文件它不起作用。

I write some code to print exceptions to file. 我写了一些代码来打印文件的异常。 It gives this line : java.lang.ClassNotFoundException : com.mysql.jdbc.Driver 它给出了这一行： java.lang.ClassNotFoundException：com.mysql.jdbc.Driver

I already added required jars to my project. 我已经为我的项目添加了必需的罐子。 I cant understand why it doesnt work ? 我不明白为什么它不起作用？

It seems that your JAR is not having the required libraries. 您的JAR似乎没有所需的库。

You need to export the application using the option Package required libraries into generated JAR . 您需要使用选项Package required libraries into generated JAR将应用程序导出Package required libraries into generated JAR 。
