jar文件问题

Question

当我尝试从netbeans运行jar文件时，它工作正常，但是当我尝试通过命令提示符运行时，它使我在线程错误中得以执行，但是当我检查任务管理器时，它表明javaw.exe正在运行。 .......确切是什么以及为什么此错误仅出现在命令提示符下？

Answer 1

compile your application with:

>javac -jar example.jar ClassName.java

Run:

>java -jar example.jar ClassName

Answer 2

Can you please paste the exception that you get.

When running from command line, you have make sure that classpath for your program is set properly.

Make user that you have set the main-class in your manifest file of you jar.
