com.mysql.jdbc.Driver运行Jar文件时出错，尽管我的构建路径

Question

我创建了一个带有rmi的java swing应用程序，并导出了Jar文件Client.Althout我的Jar文件正在运行第一个mySql连接时出现以下错误消息。当我在Eclipse中编译和运行程序时，一切都很完美，Error只作为Jar文件出现。到目前为止，我已经在这里和generell进行了搜索，已经看到问题与我的构建路径有关，但是在构建路径和类路径中包含了mysql-connecor-java-5.1.37-bin.jar。

错误讯息：

然后我的构建路径是这样的：

我必须在我的构建路径中包含更多jar，因为当我导出Jar文件时出错了并出现此错误。我在Eclipse中做过它 出口 - ＆gt; JAR文件 - ＆gt;选择目的地 - ＆gt;生成清单文件 - ＆gt;选择Main类 - ＆gt;完成

这是我的classpath

从Eclipse生成的MANIFEST.MF内部只有

Manifest-Version: 1.0 Main-Class: clientValantis.Main
