Date format manipulations
Hi, all.
I think I'm working too hard to get the end result I'm looking for. Is
there a better way?
Background: I'm working with a schema available at
http://www.openarchives.org/OAI/2.0/OAI-PMH.xsd. The fragment in
question is this:
<simpleType name="UTCdatetimeType">
<annotation>
<documentation>Datestamps are to either day (type date)
or to seconds granularity (type
oai:UTCdateTimeZType)</documentation>
</annotation>
<union memberTypes="date oai:UTCdateTimeZType"/>
</simpleType>
<simpleType name="UTCdateTimeZType">
<restriction base="dateTime">
<pattern value=".*Z"/>
</restriction>
</simpleType>
My task is to produce an XML document compliant with the schema. I need
the datetime defined as UTCdatetimeType to be in UTC format, e.g.
...
<header>
<identifier>host:repository:1</identifier>
<datestamp>2008-04-04T20:16:33.068Z</datestamp>
</header>
...
I'm doing it, but it feels like too much work to do it like this:
Calendar datestamp = Calendar.getInstance();
datestamp.setTimeZone(TimeZone.getTimeZone("UTC"));
UTCdateTimeZType dtmz =
UTCdateTimeZType.Factory.newInstance();
dtmz.setCalendarValue(datestamp);
UTCdatetimeType utcdtm = (UTCdatetimeType)
dtmz.changeType(UTCdatetimeType.type);
hdr.xsetDatestamp(utcdtm);
Is there a simpler, more straightforward way that I'm just not finding?
Thanks.

Thanks for the suggestion, Radu. I've gotten in such a rut using
*.Factory.newInstance(...) that I'd overlooked the
*.Factory.newValue(...) option, which is a bit better than what I had
done.
I thought I understood why I was having the issue (java Calendar mapping
to both types in the union, xmlbeans using the first that matches), but
its good to have it confirmed.

Re: Date format manipulations
Posted by Radu Preotiuc-Pietro <ra...@bea.com>.
There is a slightly simpler/cleaner way:
Calendar datestamp = Calendar.getInstance();
datestamp.setTimeZone(TimeZone.getTimeZone("UTC"));
UTCdateTimeZType dtmz =
UTCdateTimeZType.Factory.newValue(datestamp);
UTCdatetimeType utcdtm =
UTCdatetimeType.Factory.newValue(dtmz);
hdr.xsetDatestamp(utcdtm);
But the main reason you have to work hard is that the same Java type
(Calendar) corresponds to both union members. So if you had say a union
of int and string and did hdr.setValue("string") then it would be
obvious which of the union members "matches" but in your case it's not,
because Calendar is the Java class for both "date" and "dateTime".
XMLBeans in this case picks the first union type that matches. If you
wanted the first union member, then doing
Calendar datestamp = Calendar.getInstance();
datestamp.setTimeZone(TimeZone.getTimeZone("UTC"));
hdr.setDatestamp(datestamp);
would produce the result you wanted. But you want the second union
member, so you have to use xsetDatestamp() and a specific type to convey
this information.
Hope this makes sense,
Radu
