Hello,
You do not want to do this by touching the Dashboard.do file. This is beacuse that page is not ALWAYS the page a user will go to. The "landing page" that a user goes to after logging on is customizable by the USER, so the dashboard may not be the page everyone goes to.
The best way to implement this is to have a landing page PRIOR to the user seeing the Login Page that is part of the DLP UI.
So I would reccommend modifying the redirect page that the Vontu UI uses. If you know anything about HTML and tomcat, there is an index.html page that is the DEFAULT page that the Enforce Server will go to when trying to logon.
You can modify that landing page with what ever verbiage you want, and then once someone hits the OK button, it will then redirect it to the login page of the Enforce UI.
There are 2 different index.html pages that you will need to experiment with and possibly both.
Vontu\Protect\tomcat\webapps\ROOT
Vontu\Protect\tomcat\webapps\ProtectManager
DISCLAIMER: Make changes to the system are not reccommended and may have an impact on support and upgrades in the future.. do this at your own risk.
Good luck..
Ronak
