From the TomEE 9 console I can see that the activeMQ KahaDB is using C:\Windows\system32\activemq-data\localhost\KahaDB as its default storage directory.

Since C:\Windows\system32 is a protected folder it is causing the ActiveMQ to split out this INFO

I found this link that documents how I can custom configure the KahaDB. The configuration looks simple enough, but
I just don't know what xml file to put the configuration in? I tried server.xml but it didn't work.
Below is the content of server.xml:
