manifest file not containing an attribute

Question

Hi,

Thanks for your answers. I'm still having a fault saying manifest file does not contain a file/object attribute, after I had created my jar file for my application. I'm doubting maybe I didn't know what exactly the main-class represent in a manifest file while writing the code. please illustrate taking an example from the HelloWorld .

Thanks

Answer 1

Take a look at Setting an Application's Entry Point

EDIT:

Test.java

package pk;

public class Test{
   public static void main(String []args) {
       System.out.println("Hello World");
   }
}

mf manifest file entry

Main-Class: pk.Test

Compilation

>javac Test.java -d .

Create a Jar

>jar -cvfm my.jar mf pk

Test the jar

>java -jar my.jar
