Yes, true. But this worked 100% for the Realm with that same driver.

Someone already solved that problem. I need to a parameter "username",
not "user".

Now, I am having a different problem. My database connection is not
being released even though I am closing it. 

Could someone help me out with this? (I am inlcluding my server.xml file
just in case).

When I start up the server, however, I get the following exceptions in
the log file:
