Hi All

I tried to add the Search tool to a Site in my Sakai 10.1 OOTB
installation.  I then clicked on the Admin button of the Search tool and
got the error below.

I then enabled elasticsearch (search.enable = true), but when I then
startup Tomcat, I get errors all over the place. I would like to have a
look at the tool and the implementation thereof, but can't get that far due
to all the errors. Am I doing something wrong and has anyone else
experienced the same as I did for Sakai 10.1?
