If I have an node "label" in the xml

I have "_label" field in the class and "getLabel" and "setLabel" method.

The following is from the JAXB 2 specification (JSR-222):

8.12 Default Mapping

This section describes the default mapping of program elements. The default mapping is specified in terms of default annotations that are considered to apply to a program element even in their absence.

8.12.1 Java Identifier To XML Name

The following is the default mapping for different identifiers:

• class name: a class name is mapped to an XML name by de capitalization using java.beans.Introspector.decapitalize(class name ).
• enumtype name: enumtype name is mapped to an XML name by de capitalization using java.beans.Introspector.decapitalize(enumtype name).
• A property name (e.g. address) is derived from JavaBean access method (e.g. getAddress) by JavaBean de capitalization of the JavaBean property name java.beans.Introspector.decapitalize(JavaBeanAcc essMethod)
