There ought to be mappings for the sql.date, if not, ask for them or add
them, its faster that way. Similarly, there is support for Vector, so you
could use that to add ArrayLists. Use the source in
org/apache/axis/encoding/ser as your starting point.

sql.Date should map to xsd:datetime ; ArrayList becomes a sequence of
elements in XML . I guess part of the problem there is typing. When you
export/import a simple typed array, its obvious what you send and receive.

Note I find xsd:datetime trouble. Java runtimes add the correct timezone
info from a Calendar object, and expect the timezone to be valid on receipt.
.NET doesnt, it assumes local TZ everywhere. This leads to more confusion,
the further from GMT you are, but confusing it is when things are 8 hours
apart on a local system.

Nowadays I have given up on time and use a long instead, with that mapped to
the classic time_t datatype
