executable jar file not running

Question

I have created a runnable Jar file of quite large dimension (125,000 kb). When I run it the application inside this jar file is not shown but in the Task Manager the javaw.exe (which should be linked to this jar file) process is running. Does anyone know what the problem is and how it may be overcome?

Answer 2

您必须在主类示例中传递一些代码：如果要打开表单，请在主类中编写以下命令：-new（）.setVisible（true）;
