public class MappingForwardingService
extends AbstractService

This forwarding service will forward requests to another service, by mapping a request parameter value to a forward url. Both the request parameter name and mappings can be configured using the setIdParam(String) and setMapping(Map) methods respectively. Usually this service is configured using Spring with a bean definition like this:

<bean id="/serviceName" class="vodserver.service.ForwardingService">
        <property name="idParam" value="someReqParamName" />
        <property name="mapping">
                <map>
                        <entry key="mapping1" value="/otherService1?prm1=abc" />
                        <entry key="mapping2" value="/otherService2?prmA=xyz" />
                </map>
        </property>
</bean>

This defines a service that can be called as http://vodserver:port/serviceName?someReqParamName=mapping1, which will forward to /otherService1?prm1=abc.
