Java 从构建路径运行application.jar时出现问题

Java 从构建路径运行application.jar时出现问题,java,Java,我正试图用串行通信编写一个程序。为此,我使用了Java通信API(comm.jar)。当我从IDE(NetBeans)运行我的程序时,它可以工作,但当我试图从它的构建位置(从'C:\Users\Bipin panday\Documents\NetBeansProjects…\dist'文件夹)运行时,我的应用程序.jar没有运行 从生成位置运行时无法工作的程序代码为: CommPortIdentifier portIdentifier = portEnum.nextElement();
