Web Java Start

Front-end
#1

Pessoal estou seguindo este tutorial para executar o Web Java Start:

http://www.mballem.com/post/java-web-start

Porem quando eu executo o arquivo jnlp acontece o seguinte erro:

“Não é possível carregar o recurso : http://localhost:8080/JavaAppSart/file/appDesktop.jar”

Arquivo d Acionamento:

<jnlp spec="6.0+" codebase="http://localhost:8080/JavaAppStart/" href="desktop.jnlp">
  <information>
    <title>My First Java Web Start - Desktop</title>
    <vendor>Programando com Java</vendor>
    <homepage href="http://mballem.wordpress.com/"/>
    <description kind="short">
                  Exibe lista de estados brasileiros.
         </description>
    <offline-allowed/>
  </information>
  <resources>

  </resources>
  <application-desc main-class="com.wp.mb.appdesktop.AppDesktop"/>
  <update check="always"/>
</jnlp>[/code]

Exceção:

Segue anexo, como estão os arquivos testes no Netbeans.

Pelo que eu estou lendo, se eu entendi direito, ele diz que o arquivo jar não existe… mas eu acho que esta certo rsss
