404 Not Found Error in the Siebel Mobile Web Client
If users receive a 404 Not Found error in external data sections of the Siebel Mobile Web client, then the constructed external URL went to a valid host name but specified a URL path that does not exist. This usually indicates that a Symbolic URL is not correctly defined.
