Java webstart权限问题

我正在尝试创建一个webstart应用程序。 它现在运行，但不读取我的所有设置

当我启动jnlp文件并尝试使用Inputstream读取另一个jars资源时，就会出现问题

我已经验证了我的JAR，它们都使用相同的密钥库

我有一个叫Browser的jar，它试图读取另一个叫Bone的jar

以下是我如何读取类BoneModule中的设置：

InputStream settingsStream = IOUtil.getInputStream("bone.settings");
            InputStream defaultSettintgsStream = IOUtil
                    .getResourceAsStream("/com/mee/bone/bone.settings", BoneModule.class);
            SimpleProperties storage = new SimpleProperties(settingsStream,
                    new SimpleProperties(defaultSettintgsStream, null).getProperties());
            storage.setStoreFilename("bone.settings");
            boneSettings.addStorage(storage);

我已将jnlp文件设置为：

 <?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0+" codebase="http://ip-adress/lib" href="launch.jnlp">
 <information>
    <title>Bildlabbet</title>
    <vendor>mee</vendor>
    <offline-allowed/>
 </information>
 <security>
 <all-permissions/>
 </security>
 <resources>
    <j2se version="1.7+" initial-heap-size="32m" max-heap-size="128m" />
    <property name="jnlp.versionEnabled" value="false"/>
    $dependencies
</resources>
<application-desc
      name="Bildlabbet"
      main-class="com.mee.browser.BildlabbetBrowser"
      width="300"height="300">
</application-desc>
</jnlp>

甚至可以这样读吗？现在，我正在本地驱动器上阅读我的jar，因为这是webstart所做的

值得一提的是，我正在从临时目录中读取jar。我已尝试调试临时文件夹的文件权限

如果我从服务器（而不是本地）读取jars资源，这是否已修复

任何建议都很好

谢谢大家!

试试这个：

授予{
权限java.io.FilePermission“/dir/yourfile”，“读、写”
}
