Tarro lanzar Ejecutable desde Inicio Web

Question

Esta es mi primera vez tratando de utilizar Web Start, y yo estoy tratando de lanzar mi tarro ejecutable. Me sale el siguiente error de mi página web como hacer clic en el enlace para iniciar la jarra. ¿Puede alguien ayudarme? El ejemplo el Bloc de notas desde el tutorial funciona bien desde otro enlace en la página de prueba (JNLP y tarro en misma carpeta que tengo también). El frasco y jnlp son definitivamente en la misma carpeta, sin embargo, el frasco no se pueden encontrar. Gracias de antemano.

Estructura de carpetas:

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

JNLP del archivo:

<?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

He encontrado mi reson por qué este archivo no se cargará. Este fue un error de permisos. La cuenta se intenta acceder al archivo JAR ni tienen permisos de Windows. Que había creado el archivo JAR desde Eclipse y exportados a mi escritorio, luego se copia encima en el directorio JNLP. Esos permisos no se cambiaron para el JAR después de que el copiar / pegar.
