我正在尝试从 servlet 访问 IBM FileNet P8 V5 数据存储，需要帮助来正确配置 WebSphere。
我在装有 IBM WebSphere 的 RedHat 7 服务器上全新安装了 FN P8。
我尝试了 https://www.ibm.com/support/knowledgecenter/en/SSNW2F_5.0.0/com.ibm.p8.ce.dev.ce.doc/ss_ecl_cews.htm 上给出的示例代码
它在纯 Java 类中工作正常;连接到服务器并检索数据存储名称。
我将代码复制到servlet，但收到错误： " 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。这就是我被困住的地方。我尝试通过 JVM 设置中的 WebSphere 控制台添加 jaas.conf.WebSphere，但显然没有正确操作。

带有 servlet 的应用程序安装在同一台服务器上。
我看到你的 jaas 节为 null，这意味着它将采用 FileNetP8 作为默认节。代替空，请尝试FileNetP8WSI，因为您正在使用WSI端点进行连接。
Subject subject = UserContext.createSubject(conn, username, password, "FileNetP8WSI");
如果您提供空，它将使用"FileNetP8"，这是用于IIOP连接的jaas节
