Java webstart權限問題

我試圖創建一個webstart應用程序。它現在運行，但沒有閱讀我所有的設置。Java webstart權限問題

當我啓動jnlp文件並嘗試使用InputStream讀取另一個Jars資源時，會發生此問題。

我已經驗證了我的罐子，它們都使用相同的密鑰庫。

我有一個名爲Browser的jar試圖讀取另一個名爲Bone的jar。

這是我讀裏面我班BoneModule的設置：

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);

我已經把我的JNLP文件到這一點：

<?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>

正如你在這裏看到的，我無法讀取其他jar中的設置文件。我的客戶端和瀏覽器我的策略設置爲：

grant codebase "file:${jars}" { 
    permission java.security.AllPermission; 
}; 

grant codebase "file:/var/www/lib/*" { 
permisson java.security.AllPermisson; 
}; 

grant codebase"file:/http://ip-adress/lib/*" { 
permisson java.security.AllPermission; 
}; 

grant codebase "file:/home/ubuntu/bildlabbet/lib/*"{ 
permission java.security.AllPermission; 

grant { 
permission java.util.PropertyPermission "*", "read, write"; 
}; 

grant { 
permission java.security.AllPermission; 
};

它甚至有可能讀這樣嗎？因爲它現在正在閱讀我的jar在本地驅動器，因爲它是webstart所做的。

要提及的是即時通訊從臨時目錄中讀取jar。我已經嘗試調試臨時文件夾的文件權限。

這是固定的，如果我從服務器，而不是本地讀取罐子資源？

任何建議會很好！

謝謝！

試試這個：

grant { permission java.io.FilePermission "/dir/yourfile", "read, write" }
