Note some important points about XMLGregorianCalendar:
1) XML Schema supports three data types such as date, time and datetime and defined by three tags xsd:date, xsd:time and xsd:dateTime. While working with XML using JAXB framework then JAXB XJC maps all these types to XMLGregorianCalendar.
2) It’s possible to define xml schema for converting XMLGregorianCalendar to Date. The XJC(Binding compiler) will generate Date instead of XMLGregorianCalendar. I will show this way for you soon.
3) One more important thing, you should use constructor to create instance of GregorianCalendar instead of GregorianCalendar.getInstance(). Because it’s same as Calendar.getInstance() and can return different instances base on Local settings.
That’s it. Hope that you could catch up how to convert XMLGregorianCalendar to Date in Java and Date to XMLGregorianCalendar. You can also refer to the Complete Java XML tutorial to get more Java Xml knowledge.
Happy learing!
