How do you specify how to interpret the elements of the array? e.g. how
should this be handled? :

Object[] awkwardArray = new Object[] { new Integer(42), "42", "foo" };
statement.setObject(1, awkwardArray);

JDBC2's PreparedStatement.setArray() is the standard way: you wrap the
underlying array in an appropriate Array implementation of your own.
This also solves the problem of deciding how to interpret the array
elements: the Array interface allows you to explicitly provide a SQL
type for the elements.

However the CVS driver does not implement setArray usefully for this
case. I have an unapplied patch that was posted to the list some time
ago that implements this (getting quite old now..), which is a bit of a
nasty hack but does the job. See
