Help!

I’m trying to manually install the latest stable version of (xWiki 10.11.3) in Tomcat 9 on a Windows server, using Oracle 12c.

I put the jdbc driver in my lib folder and made the changes as directed to the xwiki.properties and the hibernate file, etc.

My database set up fine, but when I try to open xWiki for the first time, I get the following exceptions below: can anybody help?

It’s this part that is interesting :slight_smile: i.e. the root cause…

Yep the answer is generally located in the very last Root Cause.

LOL sorry guys… I wasn’t thinking, blame it on the hour I lost on daylight savings!

I looked at the last root cause and finally realized that my connection was getting rejected by our data warehouse. Made a phone call and now I’m in business… :slight_smile:

Thanks for the replies!
