How to run Java .jar without MANIFEST.MF?

问题

Is it possible to run a Java app which doesn't contain MANIFEST.MF file? Of course, there's static main method,just lacks manifest file. And the app is depending on several external .jar files.

If is this possible, how to do that?

It is possible, you can specify the class to run from the command line:

java -cp yourJar.jar your.main.Class
