I don't use NetBeans myself, but there's a good step-by-step guide which has screenshots for everything you need to build an executable jar file. 我自己不使用NetBeans，但是有一个很好的循序渐进指南，其中提供了构建可执行jar文件所需的所有屏幕截图。

In particular, did you fill in the "Main Class" property in the project properties? 特别是，您是否在项目属性中填写了“ Main Class”属性？ I know you says you've filled in the "Starting form" but that may not be the same thing... 我知道您说您已经填写了“开始表格”，但是可能不一样...

Look in the MANIFEST.MF file in the jar file. 在jar文件中的MANIFEST.MF文件中查找。 It should contain a Main-Class line containing the name of the class you want to start when invoking in this manner. 它应包含一个Main-Class行，其中包含以这种方式调用时要启动的类的名称。 If the line is there, doublecheck the spelling of both the class name and Main-Class. 如果该行在那里，请仔细检查类名和Main-Class的拼写。
