public final class JAXB extends Object
Methods defined in this class are convenience methods that combine several basic operations
in the JAXBContext
, Unmarshaller
, and Marshaller
.
They are designed
to be the prefered methods for developers new to JAXB. They have
the following characterstics:
DataBindingException
(which will have JAXBException
as its cause
. It is expected that
people who prefer the checked exception would use
the rest of the JAXB API directly.
In addition, the unmarshal methods have the following characteristic:
DataBindingException
.
Similarly, the marshal methods have the following characteristic:
DataBindingException
.
All the methods on this class require non-null arguments to all parameters. The unmarshal methods either fail with an exception or return a non-null value.

xml
- Reads the entire file as XML.public static <T> T unmarshal(URL xml, Class<T> type)
xml
- The resource pointed by the URL is read in its entirety.public static <T> T unmarshal(URI xml, Class<T> type)
xml
- The URI is turned into URL
and then
follows the handling of URL.public static <T> T unmarshal(String xml, Class<T> type)
xml
- The string is first interpreted as an absolute URI.
If it's not a valid absolute URI
,
then it's interpreted as a Filepublic static <T> T unmarshal(InputStream xml, Class<T> type)
xml
- The entire stream is read as an XML infoset.
Upon a successful completion, the stream will be closed by this method.public static <T> T unmarshal(Reader xml, Class<T> type)
xml
- The character stream is read as an XML infoset.
The encoding declaration in the XML will be ignored.
Upon a successful completion, the stream will be closed by this method.public static <T> T unmarshal(Source xml, Class<T> type)
xml
- The XML infoset that the Source
represents is read.public static void marshal(Object jaxbObject, File xml)
jaxbObject
- The Java object to be marshalled into XML. If this object is
a JAXBElement
, it will provide the root tag name and
the body. If this object has XmlRootElement
on its class definition, that will be used as the root tag name
and the given object will provide the body. Otherwise,
the root tag name is infered
from
the short class name
.

it will be overwritten.DataBindingException

to the
resource pointed by this URL. Note that not all URLs support
such operation, and exact semantics depends on the URL
implementations. In case of HTTP URLs

this will perform HTTP POST.DataBindingException
