Could not find a match for URL Workbench

Question

I am trying to test my code from workbench by sending an xml file to my @restresource global class. I have a @httpPost method through which I wan to insert the record. When I try to send a request to my class I am getting error : URL not found My class code

@RestResource(urlMapping='/Lead')
global with sharing class ParentRest {
@HttpPost
global static Lead doPost() {
    RestRequest req = RestContext.request;
    system.debug('The request ' + req);
    return null;
}
}

My workbench Url

/services/apexrest/lead

Workbench header

Content-Type: application/XML; charset=UTF-8
Accept: */*

Error on workbench:

 [ {
 "errorCode" : "NOT_FOUND",
 "message" : "Could not find a match for URL /lead"
 } ]

What will be the reason. Anyone have any idea what will be the reason? Please guide me how to solve this issue.

I have solved the issue. Solution: If you have namespace defined in salesforce you need to define it with /services/apexrest/namespace/lead
