New to Spring-ws. Problem with namespace issue

[mvPrasad Regula]

I am new to spring-ws. The following are the steps I know to do a wen services in spring
Part A
=====
1. Write an XSD --> Done
2. Write an interface --> Done
3. Write an implementation --> Done

Part B(Spring-WS stuff)
================
4. Write the web.xml --> Done
5. Write the SPring bean configuration XML file -->>>>FAILED. The problem I am facing here is as below.

    
<bean class="org.springframework.ws.server.endpoint.mapping.PayloadRootQNameEndpointMapping">
        <property name="mappings">
            <props>
                <prop key="{http://www.averconsulting.com/echo/schemas}EchoRequest"   //--> I am getting error at this line
                >echoEndpoint</prop>
            </props>
        </property>
        <property name="interceptors">
            <bean
                class="org.springframework.ws.server.endpoint.interceptor.PayloadLoggingInterceptor"
            />
        </property>
    </bean>

I am getting error at the following line of key for the property is set

<props>
<prop key="{http://www.averconsulting.com/echo/schemas}EchoRequest" //--> I am getting //error at this line
>echoEndpoint</prop>
</props>

Which ever site I visit they are saying that it should be same as the namespace. For a sample echo example which is existing on the net I can give this namespace mentioned by them. How about if I have a totally different schema for a different project. I am using Netbeans and Glassfish as server.

Just rectifying the above scentence

Everywhere it is mentioned that it should be same namespace mentioned in xsd.

My xsd has been placed in WEB-INF
