This is the way it works:
IMPORTANT: This feature will function only if you have selected External Configuration in the ConfigTool.
Now, when you bring up OM Web Viewer it will show the login screen and below it the banner file. You cannot proceed unless you click OK at the bottom
This feature was added to Web Viewer in SO01856 Cumulative Build 185 for v12.1 and is included in any build higher than that.
VERY IMPORTANT. The SPLASH Screen was found to be vulnerable and updated in LU09689 Security or Integrity Problem (Cumulative Build 239) and above
This impacted how it works. Now:
The text is streamed to the browser through a hidden HTML iframe. As the default size is very small (around 300 pixels), it is necessary to specify the required dimensions in the specialLogonInstructions.html file. In the first line, use the keywords Height and Length to specify the required height and length of the IFRAME.
Example:
Height=500,Length=800
The keywords are case-sensitive but the order does not matter.
An anchor with an href, for example <a href="webViewer.htm">Web Viewer</a> might not work in LU09689 Security or Integrity Problem (Cumulative Build 239) or later.
TIP: You may create the .html file from an MS Word document by saving it as an HTML file. Any embedded images will be saved separately in a subdirectory.
