Hi,

I am working on Centos 6x.
I installed OM v2.2 and connected it to mysql according to directions I
found on Tutorials+for+installing+OpenMeetings+and+Tools /
the newest being "Installation of OpenMeetings 2.x and 3.x in CentOS
6.5.pdf"

all went perfectly

I then installed OM v3.00 following the same directions, only changing
directory and database names.

I get the following error, but NOT being a spring bean, I don't no how to
proceed, nor am I sure I am providing the information you need to assist.

The following properties are available in the configuration:

the persistence.xml looks (partley) like this
