JAXB: XSD datatypes mapping to Java DataTypes

Below is the list of mappings from XSD data types to Java data types

XSD types	Java DataTypes
byte	byte
int	int
integer	java.math.BigInteger
decimal	java.math.BigDecimal
long	long
float	float
double	double
duration	javax.xml.datatype.Duration
date	javax.xml.datatype.XMLGregorianCalendar
dateTime	javax.xml.datatype.XMLGregorianCalendar
string	java.lang.String
nonNegativeInteger	java.math.BigInteger
nonPositiveInteger	java.math.BigInteger
unsignedByte	short
unsignedInt	long
unsignedLong	java.math.BigInteger
unsignedShort	int
anyURI	java.lang.String
base64Binary	byte [] (byte array)
boolean	boolean
ENTITIES	List
ENTITY	java.lang.String
time	javax.xml.datatype.XMLGregorianCalendar
gDay	javax.xml.datatype.XMLGregorianCalendar
gMonth	javax.xml.datatype.XMLGregorianCalendar
gYear	javax.xml.datatype.XMLGregorianCalendar
gMonthDay	javax.xml.datatype.XMLGregorianCalendar
gYearMonth	javax.xml.datatype.XMLGregorianCalendar

Whatever data types are not there in Java JAXB has created appropriate datatypes in their API, for example, XMLGregorainCalendar. Now the question is how to convert it our facourite dataypes like java.util.Date or java.sql.Date or java.util.Calendar etc. You can probably write an Adaptor class which has static methods to do all these conversion.
