Java 类位于jar中时的ClassNotFoundException

我有一个问题：

Caused by: java.lang.ClassNotFoundException: javax.transaction.SystemException

即使它位于javax/transaction/SystemException.class中jar的根

该类是否位于错误的目录中

以下是相应的日志：

我以这种方式运行jar：

sudo java -cp bidder.jar com.drbanner.bidder.MainClass

请将您的清单和文件树附加到JAR中。您是如何运行应用程序的？jar文件的路径是什么？

sudo java -cp bidder.jar com.drbanner.bidder.MainClass
