Using Spring-WS for creating a client

Sample config for WebServiceTemplate

<bean id="saajMessageFactory" class="org.springframework.ws.soap.saaj.SaajSoapMessageFactory">
    <property name="soapVersion">
      <util:constant static-field="org.springframework.ws.soap.SoapVersion.SOAP_12"/>
    </property>
  </bean>

  <bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller"
        p:contextPath="com.whatever:com.another.package"/>

  <bean id="wsTemplate" class="org.springframework.ws.client.core.WebServiceTemplate"
        p:messageFactory-ref="saajMessageFactory"
        p:defaultUri="http://whatever"
        p:marshaller-ref="marshaller"
        p:unmarshaller-ref="marshaller"/>

To specify more than 1 path for the marshaller, just use colons to separate the packages.
