Web StartからRunnable Jarを起動します。

Question

Web Startを初めて使用しようとしています。実行可能なjarを起動しようとしています。 jarを起動するリンクをクリックすると、私のWebページから次のエラーが表示されます。誰か助けてくれますか？チュートリアルのメモ帳の例は、テストページの別のリンク（JNLPと私と同じフォルダ内のjar）からうまく動作します。 jarとjnlpは確かに同じフォルダにありますが、jarファイルは見つかりません。前もって感謝します。

フォルダ構造：

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

JNLPファイル：

<?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>

私は、このファイルがロードされない理由のために私のresonを見つけました。これは権限エラーでした。 JARファイルにアクセスしようとしているアカウントがWindows権限を持っていませんでした。 EclipseからJARを作成してデスクトップにエクスポートし、JNLPディレクトリにコピーしました。これらの権限は、コピー/ペースト後のJARでは変更されませんでした。
