I can 100% sure I can connect to the mysql db 'test' with 'root'
username and empty password. Do you have mysql installed? A default
mysql installation should have a DB call 'test'
the error message I got are different:
2009-12-19 12:41:05.486:INFO::No Transaction manager found - if your
webapp requires one, please configure one.
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException:
