问题描述

我是 web-start 新手，我们正在使用 exe4j 从 One-jar 创建可执行文件.为了制作我们应用程序的网络启动版本"，我正在尝试使用指定主类的网络启动来午餐 One-JAR，但我收到以下错误 -

I new to web-start and We are using exe4j to create executable from One-jar. In-order to make a "web start version" of our application I am trying to lunch One-JAR using web start with the specified Main-Class but I am getting the following error -

 java.security.AccessControlException: access denied (java.util.PropertyPermission one-jar.main-class read)

JNLP 包含 --

    <?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" codebase="" href="">
    <information>
        <title>Applet Takes Params</title>
        <vendor>Protype example</vendor>
    </information>
    <resources>
        <!-- Application Resources -->
        <j2se version="1.5+"
              href="http://java.sun.com/products/autodl/j2se"/>
        <jar href="Application.jar" main="true" />
    </resources>
    <application-desc main-class="com.simontuffs.onejar.Boot">
  </application-desc>
   <update check="background"/>
</jnlp>

我正在尝试直接启动 Application.jar，com.simantuffs.onejar.Boot 是为 JAR 指定的主要类.我还发现这个 link 说我们不能使用 web-start 启动 One-Jar.请帮忙.

I am trying to launch a Application.jar directly and com.simontuffs.onejar.Boot is the main class specify for JAR. I am also found this link that says we can not launch One-Jar with web-start. please help.

推荐答案

access denied (java.util.PropertyPermission one-jar.main-class read)

一个网络启动应用程序.可以访问任何声明 all-permissions 的属性.如果是沙盒，则只能访问以 jnlp 为前缀的属性 &其他一些被视为安全"的 JRE 属性.

A web start app. can access any property if it declares all-permissions. If it is sand-boxed, it can only access properties prefixed with jnlp & some other JRE properties that are considered 'safe'.
