Create a new DBAccess instance for a data source.
As such, we can initiate multiple databases (data sources) at the same time.

Parameters:

dbFQPath - the fully qualified path to data source

user - user to connect to

password - password associated to user

props - a Properties object specifying extra properties
E.g. HSQLDB may requires ifexists=true for checking database existence.
Set this to null if no special properties are needed.

Throws:

DBInstanceException

loadDriver

public static void loadDriver(java.lang.String driver)
                       throws JDBCDriverException
