Lançar Jar Runnable da Web Start

Question

Esta é a minha primeira vez tentando usar Web Start, e eu estou tentando lançar meu jar executável. Eu recebo o seguinte erro de minha página da web como eu clico no link para iniciar o pote. Alguém pode me ajudar? O exemplo o Bloco de notas do tutorial funciona bem a partir de outro link na página de teste (JNLP e frasco na mesma pasta que eu tenho também). O frasco e jnlp são definitivamente na mesma pasta, mas o frasco não pode ser encontrado. Agradecemos antecipadamente.

Estrutura das pastas:

/MyApp
/MyApp/MyApp.jnlp
/MyApp/MyApp.jar

JNLP arquivo:

<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0+" codebase="http://localhost/MyApp" href="MyApp.jnlp">
   <information>
      <title>MyApp Demo</title>
      <vendor>Company Name</vendor>
   </information>
   <resources>     
    <jar href="MyApp.jar"/>   
    <j2se version="1.5+" href="http://java.sun.com/products/autodl/j2se"/>
   </resources>
   <application-desc main-class="MyAppMain"> 
    <argument>arg1</argument> 
    <argument>arg2</argument> 
  </application-desc>
</jnlp>

Answer 1

Eu encontrei o meu reson para porque este arquivo não será carregado. Este foi um erro de permissões. A conta tentando acessar o arquivo JAR não funcionavam ter permissões janelas. Eu tinha criado o JAR de Eclipse e exportados para a minha área de trabalho, em seguida, copiado sobre isso para o diretório JNLP. Essas permissões não foram alteradas para o JAR após a copiar / colar.
