從Web Start啓動Runnable Jar

這是我第一次嘗試使用Web Start，並試圖啓動我的可運行jar。當我點擊鏈接啓動jar時，我的網頁出現以下錯誤。誰能幫我嗎？本教程中的記事本示例可以在測試頁面上的另一個鏈接上正常工作（JNLP和jar也在我的文件夾中）。 jar和jnlp絕對在同一個文件夾中，但jar無法找到。提前致謝。從Web Start啓動Runnable Jar

文件夾結構：

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

JNLP文件：

<?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>

我發現我爲什麼這個文件將不會加載振振有辭。這是一個權限錯誤。試圖訪問JAR文件的帳戶沒有Windows權限。我從Eclipse創建了JAR並將其導出到桌面，然後將其複製到JNLP目錄中。複製/粘貼後，這些權限不會更改爲JAR。
