Hi Robert,

you can be 100% sure that if you have in your persistence.xml written:
Url=jdbc:derby:openmeetings
That it will NOT connect to MySQL.

The default persistence.xml that ships with OpenMeetings_1_8_x.zip is using
Apache Derby and not MySQL.
mysl_persistence.xml of course has differences to persistence.xml as it
actually are two configuration files for different database vendors.

See:
