首先，我的 jar 文件工作正常，但每次我尝试启动 .jnlp 时都会出现运行时异常，这

CacheEntry[file:/C:/Users/Erick/Documents/GitHub/TarotBuddyOnline/out/artifacts/JavaFXApp/JavaFXApp.jnlp]: updateAvailable=true,lastModified=Thu Oct 03 16:41:19 EDT 2013,length=965

我正在使用生成的 .jnlp，即使我开始新项目并尝试使用 FXML 运行 Hello World，我也会收到相同的错误。

在我添加之前

  <security>
  <all-permissions/>
</security>

我收到了这个错误

这是jnlp，

<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0" xmlns:jfx="http://javafx.com" href="JavaFXApp.jnlp">
  <information>
    <title>Sample JavaFX Application</title>

  <applet-desc  width="600" height="400" main-class="com.javafx.main.NoJavaFXFallback"  name="JavaFXApp" >
    <param name="requiredFXVersion" value="2.2+"/>
  </applet-desc>
  <jfx:javafx-desc  width="600" height="400" main-class="sample.Main"  name="JavaFXApp" />
  <update check="background"/>
</jnlp>

我试图让它在网站上运行顺便说一句，我做错了什么？

使用 JavaFX 2.2，您需要对您的应用程序进行签名才能在浏览器中使用 FXML。

JavaFX 2.2 FXMLLoader 在内部使用反射来执行它的工作——这在提供给嵌入网页的未签名沙盒应用程序的特权中不起作用。
