JWS启动中拒绝PropertyPermission访问

Question

我是Web入门的新手，我们使用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”，我尝试使用具有指定Main-
Class的网络启动功能对One-JAR进行午餐，但是出现以下错误-

 java.security.AccessControlException: access denied (java.util.PropertyPermission one-jar.main-class read)
    at java.security.AccessControlContext.checkPermission(Unknown Source)
    at java.security.AccessController.checkPermission(Unknown Source)
    at java.lang.SecurityManager.checkPermission(Unknown Source)
    at java.lang.SecurityManager.checkPropertyAccess(Unknown Source)
    at java.lang.System.getProperty(Unknown Source)
    at com.simontuffs.onejar.Boot.run(Boot.java:186)
    at com.simontuffs.onejar.Boot.main(Boot.java:137)

    at java.lang.Thread.run(Unknown Source)

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 ，而 com.simontuffs.onejar.Boot
是为JAR指定的主要类。我还发现此链接表明我们无法通过网络启动来启动One-Jar。请帮忙。

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

网路启动应用程式。可以声明任何属性all-permissions。如果是沙盒，则只能访问以jnlp＆为前缀的属性以及一些其他“安全” JRE属性。
