Holiday Sample: Error creating bean with name 'holiday'

[ceciliafava]

I'm trying the HolidayService Sample from Spring ws tutorial and the error isI dont' understand the bean holiday where is it)

Error creating bean with name 'holiday': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Unknown type of result: class javax.xml.transform.dom.DOMResult
	at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1455)
	at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:519)
	at org.springframework.beans.factory.support.AbstractAutowire

My server is Tomcat and I'm following step by step the tutorial:
The doubt is about the service, what about applicationContext configuration?, the tutorial dont' say anything about and I write:

@Service
public class HumanResourceServiceImpl  implements HumanResourceService {

    private static final Log logger = LogFactory.getLog(HumanResourceServiceImpl.class);

    public void bookHoliday(Date startDate, Date endDate, String name) {
        logger.info("Booking holiday for [" + startDate + "-" + endDate + "] for [" + name + "] ");
    }
}

and the applicationContext: because the serice is there:

<context:annotation-config />
<context:component-scan base-package="com.mycompany.hr.service"/>

Thanks! If you know about a book for me, tell me please because Spring Ws Cookbook was so advanced..
