FileNotFoundException для метода tomcat.addwebapp (), выполняющего встроенный tomcat в толстом фляге, вне целевой папки maven

Я пытаюсь запустить толстую банку где-нибудь за пределами проекта Maven.Работающий jar создается из eclipse (Export -> Runnable jar -> Извлечение необходимых библиотек в сгенерированный jar).Этот jar содержит все jar зависимостей и внешних jar-файлов в lib, а также файлы классов.

Снимок maven-зависимостей в eclipse -> Maven Dependencies

Ниже мой Основной класс выполняется из исполняемого фляги. 

 String contextPath = "/";
 String appBase = "webapp/";  

 Tomcat tomcat = new Tomcat();     
 tomcat.setPort(8081);
 tomcat.getHost().setAppBase(appBase);

 String path=null;
String decodedPath=null;
 try {
    path=App.class.getProtectionDomain().getCodeSource().getLocation().getPath();

    decodedPath = URLDecoder.decode(path, "UTF-8");
        System.out.println("path of Main==>"+decodedPath);
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

 ClassLoader cl= App.class. getClassLoader();

 System.out.println("0===>"+cl.getResource("webapp/" ));
 System.out.println("1 getPath===>"+cl.getResource("webapp/").getPath());
 System.out.println("2 toExternalForm===>"+cl.getResource("webapp/").toExternalForm());
 System.out.println("3 toString===>"+cl.getResource("webapp/").toString());
 System.out.println("4. getFile===>"+cl.getResource("webapp/").getFile());


 File f = new File(cl.getResource("webapp/").toString());
 Context webContext = tomcat.addWebapp(contextPath, f.toString());  //here i am getting File Not found Exception


     try {

          Desktop.getDesktop().browse(new URL("http://localhost:8081/jsp/Archive.jsp").toURI());

         } catch (Exception e) {

           e.printStackTrace();
          }


    tomcat.start();
    tomcat.getServer().await();


     System.out.println("  tomcat started........");


}

Я получаю значение ниже Ошибка в строке Context webContext = tomcat.addWebapp(contextPath, f.toString()); во время выполнения jar runnibg как java -jar fatFromEclipse.jar в E:/JAR

E:\JAR>

Пожалуйста, помогите мне решить проблему.Я много искал, но большинство решений, которые я нашел, запустили jar в целевой папке проекта maven.Здесь я хочу распространить jar в целом, так что другому пользователю просто нужно дважды щелкнуть по нему и запустить внутри него веб-приложение.Заранее спасибо!
