Hi All,

I'm looking for some help trying to find out why I can not get Dspace
version 5.3 to load in tomcat.

Right now I have a Centos 7 machine, with Tomcat running through HTTPS.
I've check that the connector is working between httpds and tomcat because
tomcats start-up page is viewable. I've downloaded the 5.3 source, compiled
it and moved the xmlui interface into the webapps area of tomcat, replacing
the ROOT folder content with the xmlui folder content.

I've checked the log files and I'm seeing the following error:

I'm running postgres, check that it is running and that I'm able to connect
to the database.

Thanks for any help.
