Не удается развернуть пример приложения Java Web Start.

Я только начинаю создавать приложение Java Web Start. Я не могу правильно развернуть его локально, так как продолжаю получать следующее исключение

Я следую следующим руководствам по JWS

А) Официальная документация по Java

Б) Java Web Start (Jnlp), пример Hello World

Я сделал следующие шаги:

1. Упаковал мои файлы .class в исполняемую банку.

2. Подписал банку

3. Создал файл jnlp

4. Создал html файл

Поместили банку, jnlp и html-файл в один каталог JWS и вызвали html-файл.

JWS\

Demo.jar
NewFile.html
Test.jnlp

Мой файл Test.jnlp выглядит так:

 <?xml version="1.0" encoding="utf-8"?>
    <jnlp spec="1.0+" codebase="http://localhost:8080/" href="Test.jnlp">
        <information>
            <title>Jnlp Testing</title>
            <vendor>SUM</vendor>
            <homepage href="http://localhost:8080/" />
            <description>Testing Testing</description>
        </information>
        <security>
            <all-permissions/>
        </security>
        <resources>
            <j2se version="1.6+" />
            <jar href="Demo.jar" />
        </resources>
        <application-desc main-class="com.mytest.TestJnlp" />
    </jnlp>
