XMLGregorianCalendar to DateTime Java

Question

When I get the DateTime from XML it is XMLGregorianCalendar:

2010-12-02T10:00:00

Than I make a String that looks like this:

2010-12-02 10:00:00

But when I try to parse it into a workable DateTime (joda.datetime) via:

DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd HH:mm:ss");
DateTime dt = formatter.parseDateTime("2010-12-02 10:00:00");

It returns this:

2010-12-02T10:00:00.000+01:00

Where I want it to look like the String but than as DateTime so I can use it....

Answer 1

The correct way to do this is using the javax.xml.bind.DatatypeConverter class which provides a way to create java.util.Date or java.util.Calendar from the String. You can then easily convert that to Joda time if you want to.

DatatypeConverter docs: http://jaxb.java.net/nonav/2.2.4/docs/api/javax/xml/bind/DatatypeConverter.html

Answer 2

I assume the date string you're getting back is basically dt.toString()

You need to format the date using the formatter you have created, otherwise the format bares no relevance. Try this:

System.out.println(formatter.print(dt));

When you set the date using the formatter it purely uses the format you've defined to parse the string... this does not have any effect on the DateTime object so you still need to use your formatter when converting it back to a string
