Package javax.xml.bind
Class JAXB
java.lang.Object
javax.xml.bind.JAXB
Class that defines convenience methods for common, simple use of JAXB.
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:
- Generally speaking, the performance is not necessarily optimal. It is expected that people who need to write performance critical code will use the rest of the JAXB API directly.
- Errors that happen during the processing is wrapped into
DataBindingException
(which will haveJAXBException
as itscause
. 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:
- Schema validation is not performed on the input XML.
The processing will try to continue even if there
are errors in the XML, as much as possible. Only as
the last resort, this method fails with
DataBindingException
.
Similarly, the marshal methods have the following characteristic:
- The processing will try to continue even if the Java object tree
does not meet the validity requirement. Only as
the last resort, this method fails with
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.

Method Details
-
unmarshal
Reads in a Java object tree from the given XML input.- Parameters:
xml
- Reads the entire file as XML.
-
unmarshal
Reads in a Java object tree from the given XML input.- Parameters:
xml
- The resource pointed by the URL is read in its entirety.
-
unmarshal
Reads in a Java object tree from the given XML input.- Parameters:
xml
- The URI isturned into URL
and then follows the handling of URL.
-
unmarshal
Reads in a Java object tree from the given XML input.- Parameters:
xml
- The string is first interpreted as an absolute URI. If it's nota valid absolute URI
, then it's interpreted as a File
-
unmarshal
Reads in a Java object tree from the given XML input.- Parameters:
xml
- The entire stream is read as an XML infoset. Upon a successful completion, the stream will be closed by this method.
-
unmarshal
Reads in a Java object tree from the given XML input.- Parameters:
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.
-
unmarshal
Reads in a Java object tree from the given XML input.- Parameters:
xml
- The XML infoset that theSource
represents is read.
-
marshal
Writes a Java object tree to XML and store it to the specified location.- Parameters:
jaxbObject
- The Java object to be marshalled into XML. If this object is aJAXBElement
, it will provide the root tag name and the body. If this object hasXmlRootElement
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 isinfered
fromthe short class name
. This parameter must not be null.xml
- XML will be written to this file. If it already exists, it will be overwritten.- Throws:
DataBindingException
- If the operation fails, such as due to I/O error, unbindable classes.
-
marshal
Writes a Java object tree to XML and store it to the specified location.- Parameters:
jaxbObject
- The Java object to be marshalled into XML. If this object is aJAXBElement
, it will provide the root tag name and the body. If this object hasXmlRootElement
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 isinfered
fromthe short class name
. This parameter must not be null.xml
- The XML will besent
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 ofHTTP URLs
, this will perform HTTP POST.- Throws:
DataBindingException
- If the operation fails, such as due to I/O error, unbindable classes.
-
marshal
Writes a Java object tree to XML and store it to the specified location.- Parameters:
jaxbObject
- The Java object to be marshalled into XML. If this object is aJAXBElement
, it will provide the root tag name and the body. If this object hasXmlRootElement
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 isinfered
fromthe short class name
. This parameter must not be null.xml
- The URI isturned into URL
and then follows the handling of URL. See above.- Throws:
DataBindingException
- If the operation fails, such as due to I/O error, unbindable classes.
-
marshal
Writes a Java object tree to XML and store it to the specified location.- Parameters:

. This parameter must not be null.xml
- The string is first interpreted as an absolute URI. If it's nota valid absolute URI
, then it's interpreted as a File- Throws:
DataBindingException
- If the operation fails, such as due to I/O error, unbindable classes.
-
marshal

, it will provide the root tag name and the body. If this object hasXmlRootElement

-
