java - Create an executable jar for Swing app -

-

i have created java application called app.java. uses gson. hence created jar gson.jar , created manifest file (manifest.mf) following content.

manifest-version: 1.0 class-path: test.jar gson.jar main-class: app

i created test.jar using following command:

jar cfm test.jar manifest.mf *

edit: jar cfm test.jar manifest.mf * is producing jar seen on disk.

and run using 

java -jar test.jar

the application throws classnotfoundexception exitlistener. when code uses exitlistner removed, runs normal run using java app. missing?

either add jar has exitlistener class in in class-path

class-path: test.jar gson.jar <exitlistenerjar>

or write own exitlistener , use in app.

edit

on other thought can use code , add application

import java.awt.event.windowadapter; import java.awt.event.windowevent;  public class exitlistener extends windowadapter {     public void windowclosing(windowevent event) {         system.exit(0);     } }

php - Changing the visibility scope of parent methods in child classes -

-
i've got validator class , uservalidator class extends it. my validator has public method setrule(...) public visibility. when extend want change visibility of setrule(...) parent method private/protected within child it's visible child , no outsiders can call method from child. is possible? if so, how achieve it? from architectural point of view not recommended. stated in comments clean way set method protected children can access it. i cannot think of single use case put me in need call public method on parent class not allowed call on child class. that's against open/closed principle. classes should open extension, not modification. since not question i'll provide way how can achieved though. note: this method makes use of class responsible instantiation it's hack. solution not make use of php's native language features when throwing accessibility errors. first let's define classes had <?php class validator { ...
