从启动Web Start的运行的JAR

Question

这是我第一次尝试使用网络开始，我试图启动我运行的JAR。我碰到下面的错误，从我的网页，我点击启动罐子的链接。谁能帮我吗？从本教程中的记事本示例工作从测试页面上的其他链接罚款（同一文件夹JNLP和JAR，因为我有太多）。罐子和JNLP肯定是在同一个文件夹中，但罐子里无法找到。由于事先。

的文件夹结构：

/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>

Answer 1

我发现我为什么这个文件将不会加载振振有辞。这是一个权限错误。该帐户试图访问没有必须窗户权限的JAR文件。我创造了Eclipse中的JAR并远销到我的桌面，然后复制过来到JNLP目录。这些权限没有改变的复制/粘贴后的JAR。
