После создания .jar из моей IDE я не могу запустить его

Question

Я не знаю, существует ли этот вопрос и нашел ли он ответ, но сейчас я ищу в Google и даже на этом сайте уже месяц, но я не нашел решения своей проблемы.

Я разрабатываю приложение для управления запасами с NebtBeans 8.2 и EclipseLink JPA 2.1 с jdk 8.

Вот моя проблема: когда я компилирую и запускаю с IDE, все работает, кроме предупреждений, но один разЯ сгенерировал .jar и пытаюсь запустить, программа вылетает и выдает мне такую ​​ошибку:

java -jar "/home/instantech/Bureau/JAVA Projects/AfricaBadja/dist/AfricaBadja.jar"

Это мой ManagerEntity, который инициализирует соединение с базой данных:

package Entity;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;

import javax.persistence.Persistence;

/**
 *
 * @author instantech
 */
public class ManagerEntity {

    private final EntityManagerFactory emfactory;
    private final EntityManager entitymanager;

    public ManagerEntity() {
        this.emfactory = Persistence.createEntityManagerFactory("AfricaBadjaPU");
        this.entitymanager = this.emfactory.createEntityManager();
    }

    public EntityManagerFactory getEmfactory() {
        return emfactory;
    }

    public EntityManager getEntitymanager() {
        return entitymanager;
    }

    public void close() {
        this.entitymanager.close();
        this.emfactory.close();
    }

    public boolean save(Object object) {
        try {
            this.getEntitymanager().getTransaction().begin();
            this.getEntitymanager().persist(object);
            this.getEntitymanager().getTransaction().commit();
            this.close();
            return true;
        } catch (Exception e) {
                System.err.println("Error : " + e.getMessage());
        } 

        return false;

    }

    public boolean remove(Object object, Integer id) {
        try {
            this.getEntitymanager().getTransaction().begin();
            object = this.getEntitymanager().find(object.getClass(), id);
            this.getEntitymanager().remove(object);
            this.getEntitymanager().getTransaction().commit();
            this.close();
            return true;
        } catch (Exception e) {
            System.err.println("Error : " + e.getMessage());
        }

        return false;
    }


}

Если кто-то может помочь мне исправить эту ошибку.
