我是web-start的新手,我们正在使用exe4j从One-jar创建可执行文件。为了制作我们的应用程序的“web启动版本”,我正在尝试使用指定的Main-Class使用web start午餐One-JAR,但是我收到以下错误 -
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.simontuffs.onejar.Boot 是为JAR指定的主类。我也发现这个link表示我们无法通过web-start启动One-Jar。请帮忙。
答案 0 :(得分:3)
access denied (java.util.PropertyPermission one-jar.main-class read)
一个网络启动应用。如果声明all-permissions
,则可以访问任何属性。如果是沙盒,则只能访问前缀为jnlp
&amp;的属性。其他一些被认为是“安全”的JRE属性。
