在cmd或Powershell中,我执行java -jar file.jar(javaw不返回任何内容,但也不运行程序)。

它使用swing,当我运行它时:

Exception in thread "AWT-EventQueue-0" java.lang.NoSuchMethodError: javax.swing.JDialog.setAutoRequestFocus(Z)V
        at file.fileView.initComponents(fileView.java:852)
        at file.fileView.<init>(fileView.java:42)
        at file.fileApp.startup(fileApp.java:50)
        at org.jdesktop.application.Application$1.run(Application.java:171)

        at java.awt.EventDispatchThread.pumpEvents(Unknown Source)
        at java.awt.EventDispatchThread.run(Unknown Source)

它说他们不是.requestFocus的方法。

这是使用Netbeans自动生成的,它在Netbeans中运行良好。但是,它不在cmd / powershell中。

谢谢,

我相信你在netbeans中使用java 7,并且你从命令行使用旧版本的java。 setAutoRequestFocus是java 7的新功能。
