在 glassfish 2.1 中從 toplink 移動到 eclipselink 時出現安全異常

我的應用程序在 toplink 上執行良好，但我需要一些 eclipselink 功能，所以我決定交換。

我將提供者更改persistence.xml為：

<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>

並添加了以下屬性（儘管我不確定是否需要）：

<property name="eclipselink.target-server" value="SunAS9"/>

我已經嘗試eclipselink.jar用我的應用程序打包，我已經嘗試$GFHOME/lib通過 glassfish 管理 ui 將其放入並添加到類路徑後綴中。無論我做什麼，我都會得到：

並且該應用程序未部署。

編輯 - 我嘗試更改為安全設置，但遇到了另一個問題

我會認為以下（已經在 server.policy 中）允許 eclipselink.jar完全訪問，但顯然不是。

// Core server classes get all permissions by default
grant codeBase "file:${com.sun.aas.installRoot}/lib/-" {
   permission java.security.AllPermission;
};

我添加了以下內容：

grant {
   permission java.security.AllPermission;
};

現在我得到：

WARNING: "IOP00810257: (MARSHAL) Could not load class org.eclipse.persistence.indirection.IndirectList"

在客戶端

我剛剛意識到的編輯是GlassFish v2.1——讓 Application Client 和 Eclipselink 一起工作？並確保 jar 與應用程序捆綁在一起，它現在可以工作了。

根本原因是 GlassFish 在啟用了 SecurityManager 的情況下執行，而 EclipseLink 沒有在 GlassFish V2 中執行所需的所有權限。TopLink Essentials 獲得了 GlassFish 的特殊權限，要解決您的問題，只需將這些權限擴展到 EclipseLink。此部落格詳細介紹瞭如何為 GlassFish 配置安全策略。
