public static final DateFormat getDateTimeInstance()
Gets the date/time formatter with the default formatting style for
the default locale.
i.e. it is the server locale.

Hi Gurkan!
Thanks for asking Gavin. It was clear to me that getDateTimeInstance always uses the servers Locale, but thats exactly the problem.
I sent an example why this is a problem to the jboss list already yesterday in the evening, but my message waits for moderator approval, and it seems that the moderator is on vacation (sent another mail a few days ago) :(
My original mail:
Question about parsing Date fields in XML based metadata
Hi!
It's a bit late so please excuse me if my thoughts/sentences are a bit weird.
The web_beans-1.0-pr-spec has the following definition in section 9.2.5:
> The initial value of a field of type java.util.Date or
> java.util.Calendar is specified using a format that can be
> parsed by java.text.DateFormat.getDateTimeInstance().parse().
Now my question: DateFormat.getDateTimeInstance() is Locale aware. This may not always be positive.
I'm working on international projects, and if I build a WAR in vienna (Locale de_AT), and my colleagues in mountain view (Locale US) and Bangalore (maybe Locale hi_IN) like to deploy it, then it's very likely that they get parsing exceptions for e.g. default values provided via web-beans XML definition, isn't it?
Shouldn't we better use e.g. the xs:dateTime format like in SOAP?
http://www.w3.org/TR/xmlschema-2/#dateTime
SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ");
Another question:
Let's say I have a Calendar field in MyWebBean.java. Which kind of Calendar should it actually inject? GregorianCalendar? Or should it throw a DefinitionException? (Generall question about handling of abstract members)
