我正在尝试从 servlet 访问 IBM FileNet P8 V5 数据存储，并且需要帮助以正确获取 WebSphere 配置。
我在带有 IBM WebSphere 的 RedHat 7 服务器上全新安装了 FN P8。
它在普通的 Java 类中运行良好；连接到服务器并检索数据存储名称。
我将代码复制到 servlet，但出现错误：“ com.filenet.api.exception.EngineRuntimeException: FNRCS0005E: SECURITY_INVALID_CREDENTIALS: 不允许访问内容引擎，因为内容引擎 API 库或 Web 服务接口 (WSI)侦听器找不到所需的安全上下文信息。在安全上下文中找不到预期的凭据“
根据教程，我需要设置运行时环境。这就是我坚持的地方。我尝试通过 JVM 设置中的 WebSphere 控制台添加 jaas.conf.WebSphere，但显然没有正确执行。

带有 servlet 的应用程序安装在同一台服务器上。
