The XStreamMarshaller does not require any configuration, and can be configured in an application context directly. To further customize the XML, you can set an alias map, which consists of string aliases mapped to classes:

<beans>

    <bean id="xstreamMarshaller" class="org.springframework.oxm.xstream.XStreamMarshaller">
        <property name="aliases">
            <props>
                <prop key="Flight">org.springframework.oxm.xstream.Flight</prop>
            </props>
        </property>
    </bean>
    ...

</beans>

	Note
	Note that XStream is an XML serialization library, not a data binding library. Therefore, it has limited namespace support. As such, it is rather unsuitable for usage within Web services.
