Hi,
I am using Spring 3.0.5.Release MVC for exposing a webservice and below is my

Following is what i am doing in controller (QPRController)
@RequestMapping(value = "/clientMetrics/{clientId}", method = RequestMethod.GET)
public ModelAndView getBatchProgressMetrics(@PathVariable String clientId) {
List<BatchProgressMetrics> batchProgressMetricsList = null;
batchProgressMetricsList = batchProgressReporter.getBatchProgressMetricsForClient(clientId);
ModelAndView mav = new ModelAndView("QPRXmlView", BindingResult.MODEL_KEY_PREFIX + "batchProgressMetrics", batchProgressMetricsList);
return mav;
}
And i get the following:
SEVERE:
Servlet.service() for
servlet rest threw exception
javax.
servlet.ServletException: Unable to locate object to be marshalled in model: {org.springframework.validation.BindingResult.batchProgressMetrics=
Note that BatchProgressMetrics is an interface so my MAV is returning list of BatchProgressMetrics objects and i have entry for its impl in classes to be bound in
servlet.xml.
Can you please help me as to what i am doing wrong. And yes if i send just batchProgressMetricsList.get(0) in MAV it just works fine.
