I have coded using following example
http://justcompiled.blogspot.com/2010/11/web-service-client-with-spring-ws.html
The following changes i have done:
Genereate classes using wsconsume batch file from jboss bin,
I have kept jars

saaj1.3.jar, spring-ws-core-1.0.4.jar,spring-xml-1.0.4.jar
spring-oxm-tiger-1.0.4.jar,spring-oxm-1.0.4.jar 

in jboss/../lib

Following is in my spring configuration file:

<bean id="messageFactory" class="org.springframework.ws.soap.saaj.SaajSoapMessageFactory">
        <property name="messageFactory">
            <bean class="com.sun.xml.messaging.saaj.soap.ver1_1.SOAPMessageFactory1_1Impl"/>
        </property>
    </bean>

    <bean id="test1ObjectFactory" class="test.webservices.ObjectFactory"/>
    <bean id="test1ServiceMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
        <property name="contextPath" value="test.webservices" />
    </bean>
    <bean id="test1ServiceTemplate" class="org.springframework.ws.client.core.WebServiceTemplate">
        <constructor-arg ref="messageFactory" />
        <property name="marshaller" ref="test1ServiceMarshaller"></property>
        <property name="unmarshaller" ref="test1ServiceMarshaller"></property>
        <property name="messageSender">
            <bean
                class="org.springframework.ws.transport.http.CommonsHttpMessageSender">
            </bean>
        </property>
        <property name="defaultUri" value="${webservice.url}" />
    </bean>
    <bean id="test1ServiceClient" class="test.webservices.test1ServiceClient">
        <constructor-arg ref="test1ServiceTemplate"></constructor-arg>
        <property name="test1ObjectFactory" ref="test1ObjectFactory"></property>
    </bean>

Now i have replaced everything and place webservice 1.5.0 jar. Stil i am facing this problem, Previously it worked. I haven’t done much chanegs. is any thing disturbed in my code? How to chesk ..How to track this. Any help is highly appreciated.
My ObjectFactory is simple:

@XmlRegistry
public class ObjectFactory {

    /**
     * Create a new ObjectFactory that can be used to create new instances of schema derived classes for package: test.webservices
     * 
     */
    public ObjectFactory() {
    }

    /**
     * Create an instance of {@link xxxResponse }
     * 
     */
    public XxxResponse createxxxResponse() {
        return new xxxResponse();
    }

    /**
     * Create an instance of {@link xxx }
     * 
     */
    public Xxx createXXX() {
        return new XXX();
    }

}

Input
Following are classlevel annotations

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "xxxData"
})
@XmlRootElement(name = "Xxx")

Response:

  @ XmlAccessorType(XmlAccessType.FIELD)
    @XmlType(name = "", propOrder = {
        "xxxResult"
    })
    @XmlRootElement(name = "XxxResponse")

The exception you’re getting is telling you that the JAXB context is expecting to receive elements with no XML namespace. It’s expecting this because your JAXB-annotated classes do not have a namespace defined anywhere. You’d expect to find this declared as @XmlNamespace, somewhere in the bound classes (or in package-info.java), but you don’t have that anywhere.

Spring-WS, however, is receiving responses that do have a namespace (the http://yyy.org in your example), and so the unmarshalling fails.

What I can’t explain is how this ever worked with Spring-WS 1.5.x – the namespace mismatch should fail for every version.

Whatever tool you used to generate the JAXB classes should have produced a package-info.java file that declared the namespace. Are you sure it’s not in there somewhere?
