How to write a concurrent web service client

[scranthdaddy]

Hi, I have a requirement to parse a file that contains about 5,000 records and for each record, call a web service. Since each request can take up to 1 minute to get a response back, I would like to make the service calls concurrently. I am honestly not sure where to start and am looking for best practice suggestions.

Here is how I have defined my spring beans (this actually works):

    <bean id="xboxService" class="com.scranthdaddy.xbox.service.XboxServiceImpl">
        <property name="webServiceTemplate" ref="webServiceTemplate"/>
    </bean>

    <bean id="marshaller" class="org.springframework.oxm.xmlbeans.XmlBeansMarshaller"/>

    <bean id="webServiceTemplate" class="org.springframework.ws.client.core.WebServiceTemplate">
        <property name="defaultUri" value="http://xbox2.scranthdaddy.com"/>

        <property name="marshaller" ref="marshaller"/>

        <property name="unmarshaller" ref="marshaller"/>
    </bean>

Thanks!
