从servlet访问FileNet内容引擎
我正在尝试从servlet访问IBM P8 V5数据存储，并且需要帮助来正确地进行WebSphere配置。
我在装有RedHat 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
它在普通的Java类中工作得很好；连接到服务器并检索数据存储名称。
我将代码复制到servlet中，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FNRCS0005E库或SECURITY_INVALID_CREDENTIALS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所需的凭据”
根据本教程，我需要设置运行时环境。这就是我被困的地方。我尝试通过WebSphere控制台在JVM设置中添加jaas.conf.WebSphere，但显然没有正确操作。

// Make connection.

Subject subject = UserContext.createSubject(conn, username, password, null);
UserContext.get().pushSubject(subject);
try

// Get default domain.
Domain domain = Factory.Domain.fetchInstance(conn, null, null);
System.out.println("Domain: " + domain.get_Name());
// Get object stores for domain.
ObjectStoreSet osSet = domain.get_ObjectStores();
ObjectStore store;
Iterator osIter = osSet.iterator();
while (osIter.hasNext())
{
store = (ObjectStore) osIter.next();
System.out.println("Object store: " + store.get_Name());
}
System.out.println("Connection to Content Engine successful");
}
finally
{
UserContext.get().popSubject();
}
out.println("<p>Completed</p>");
out.println("</body></html>");
}
/**

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
doGet(request, response);
}
}带有servlet的应用程序安装在同一台服务器上。

我看到您的jaas节为null，这意味着它将接受FileNetP8作为默认节。在使用WSI端点进行连接时，尝试使用FileNetP8WSI而不是null。
Subject subject = UserContext.createSubject(conn, username, password, "FileNetP8WSI");如果提供null，它将使用"FileNetP8“这是用于IIOP连接的jaas节。
