Applies to:Oracle AutoVue VueLink Integration - Version 20.0.0 and later
Information in this document applies to any platform.
In this particular example AutoVue is integrated with Web Center Content (WCC) and WCC is integrated with Oracle Access Manager (OAM) so that all users are authenticated to UCM using SSO (single sign on). The way this works is that first the user requests are proxied through Oracle HTTPS Server (OHS). The requests are then passed over to OAM which redirects the client URL to the UCM SSO page. The below architectural diagram illustrates this setup.
The following error message shows up when a user tries to view any file using AutoVue from WCC:
The above error points to the machine where OHS Server is installed. The HTML source page of the AutoVue Applet also shows that the client is attempting to communicate with the VueServlet located on the OHS machine but both the VueServlet and VueLink are installed on a different machine. This is an excerpt of the HTML source page that embeds the AutoVue Applet:
Integrated UCM with OAM so that users can authenticate to UCM using single sign on.
