java.util.Calendar - Why?
Hi,
Based on the documentation, it appears that xsd:dateTime is mapped to
java.util.Calendar. Why is that? Wouldn't java.util.Date make more sense?
Thanks

That is certainly not true. Contrary to some people's beliefs,
java.util.Date is alive and well in the latest JDK ;-)

Re: sample code: using java.util.Date instead of java.util.Calendar
Posted by Dennis Sosnoski <dm...@sosnoski.com>.
From the Schema specification, "dateTime represents a specific instant
of time". Although a timezone-like offset from UTC is allowed in the
representation of a dataTime value, as I understand it this is not part
of the dateTime *value* - in other words, it's just a convenience that
is meant to be stripped away during parsing of the value, just like
leading zeroes on a number. This is implied by both the definition of
dateTime and by the canonical representation, which does not allow an
offset.
That makes the (non-deprecated) java.util.Date the closest match to a
dateTime. The problem is that people keep trying to add timezone
information (even though it's not supported by Schema), which is
apparently why the JAX-RPC spec requires using Calendar instead.
Calendar is specifically "for converting between a Date object and a set
of integer fields such as YEAR, MONTH, DAY, HOUR, and so on", and
requires a specific time zone and associated set of conversion rules in
order to be meaningful. Trying to match up a Schema dateTime with a
Calendar is ambiguous at best - for instance, what timezone do you
attach to 2003-10-26T01:15:00-05:00 (which can be either 1:15 am CDT or
1:15 am EST, if I got my math right).
I think this really is an error in the JAX-RPC spec, though I doubt
they'll be willing to make a change. You know Schema better than I do,
Stu - what do you think?

sample code: using java.util.Date instead of java.util.Calendar
Posted by "Stu Halloway (DevelopMentor)" <st...@develop.com>.
Hi,
In response to "ow"s request for java.util.Date <-> xsd:dateTime
conversion, I have written an Axis sample that uses a custom generator
in WSDL2Java to bind dateTime to java.util.Date instead of
java.util.Calendar. You can download the sample set at [1], the sample
is called StaffLocator.
Note: I am not endorsing (or condemning) this approach and I understand
that this mapping is contra the JAX-RPC spec. It's just a sample. :-)
Please let me know if there are better approaches or if there are other
samples you would like to see.

Why force people who do not need the power of Calendar to go through conversion
(say, 5000 records for every call)? People who want to use Calendar will also
have to go through conversion since you can't store Calendar in the database
and the rest of JDK expects Date all over the place, not Calendar.
Sounds like a very strange design choice to me.

Ahem... I would complain had they not chosen to use Calendar.
Calendar.getTime() makes conversion to a Date object easy, and Calendar
is much more powerful. Date doesn't support TimeZones very well at all.
Of course, there's more pain involved than there would have been in
java.util.Date had been implemented RIGHT the first time, but that's a
whole different ballgame. :-)

Yes, this is bad since it means endless conversions between
java.util.Date/java.sql.Date and the Calendar.
I'm surprised no one complained yet.

Mark,
Apache Axis implements JAX-RPC 1.0 Spec. We cannot release a version of Axis
if we don't pass the TCK (http://www.jcp.org/en/resources/tdk) for JAX-RPC
1.0. The specification states that xsd:dataTime be mapped to
java.util.Calendar. If you have a problem with the spec, there is a

Apache Axis implements JAX-RPC 1.0 Spec. We cannot release a version of Axis if we don't pass the
