how i can log on xfire with log4j for requests and responses in XML SOAP

Hi all I have a web service with xfire and spring 3.0, I need to send to logg requests and responses xml web service, I have been looking but can not find anything.

hope you can help me as integrate with log4j.

that my code in my servlet.xml:

    <bean id="interfazXFireService"  class="org.codehaus.xfire.spring.remoting.XFireExporter">
      <property name="serviceFactory">
         <ref bean="xfire.serviceFactory" />
      </property>
      <property name="xfire">
         <ref bean="xfire" />
      </property>
      <property name="serviceBean">
         <ref bean="remoteMyServiceXfire" />
      </property>
      <property name="serviceClass">
         <value>
            com.test.xfire.service.RemoteMyServiceXfire
         </value>
      </property>
   </bean>  

I solved the problem agreando few handlers input, output and in case of failures, I also modified my log4j.properties file by adding the corresponding lines.

I have been guided by the following link: http://docs.codehaus.org/display/XFIRE/Logging

stay well and my code:

<bean id="LoggingHandler" class="org.codehaus.xfire.util.LoggingHandler"></bean>
    <bean id="DOMInHandler" class="org.codehaus.xfire.util.dom.DOMInHandler"></bean>
    <bean id="DOMOutHandler" class="org.codehaus.xfire.util.dom.DOMOutHandler"></bean>

    <bean id="interfazXFireService" class="org.codehaus.xfire.spring.remoting.XFireExporter">
    <property name="inHandlers">
    <list>
        <ref bean="DOMInHandler" />
        <ref bean="LoggingHandler" />
    </list>
    </property>
    <property name="outHandlers">
    <list>
        <ref bean="DOMOutHandler" />
        <ref bean="LoggingHandler" />
    </list>
    </property>
    <property name="faultHandlers">
        <list>
        <ref bean="DOMOutHandler" />
        <ref bean="LoggingHandler" />
    </list>
    </property>
    <property name="serviceFactory">
        <ref bean="xfire.serviceFactory" />
    </property>
    <property name="xfire">
        <ref bean="xfire" />
    </property>
    <property name="serviceBean">
        <ref bean="remoteMyServiceXfire" />
    </property>
    <property name="serviceClass">
        <value>
            com.test.xfire.service.RemoteMyServiceXfire
        </value>
    </property>
</bean> 

and my stay well log4j.properties file:

log4j.category.org.codehaus.xfire = ALL
log4j.category.org.apache.commons.httpclient = ALL
log4j.category.httpclient.wire = ALL
