I have to create a jar file. I’m a beginner. I created a manifest file as forjar.txt which contains,

Main-Class: gmain

where gmain is my java file name. In command prompt, I compiled it and typed the following command.

jar cfm v.jar forjar.txt gmain.class

It created a jar file. But, while I run it, nothing happens. While I compile, nearly 25 classes get created, because my file includes many classes within it. So, should I include that too while creating jar file? Or is there any simple way such that including the entire contents of a particular folder. My folder contains images too that are needed by the program. Kindly guide me.
