Hi,
I would restart Virtual DataPort server followed by Virtual DataPort Information Self-Service Tool server and try to launch the Virtual DataPort Information Self-Service Tool.
From the logs, it appears the internal Derby database might not be stopped properly before the last shutdown.
Additionally, if you still need help and if you are a user with valid Support account, you may open a support case at the [Denodo Support Site](https://support.denodo.com/) and the support team will help you.
Hope this helps!
