How to set 'service' dyanmically in HttpInvokerServiceExporter

How could I retrieve the exporter so that I can set the service (bean) attribute dyanmically? When is service exported? Is it at the time when servlet initializes or it is lazily loaded when the first client makes the (remote) call? I think the remote service servlet (or something similar) is initilized/loaded when Spring Dispatcher servlet initializes? If that is the case, I guess I could not set the service bean dynamically?


Thanks for any help,
