My Resource File

@Path("/configset")
public class ConfigSetResource {   
    @POST
@Path("/id{configsetid: (/[^/]+?)?}")
@Consumes({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
@Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
public ConfigSetResponse getConfigSet(@PathParam("configsetid") String sConfigSetId)    throws    Exception {
     //Code
    }
    }

Trying to access my resource API using below URL
ipaddress:8080/ConfigLiteJersey2/config/configset/id

Getting HTTP status 404 Not found.

Looks like I am not giving right servletclass mapping in web.xml. Please share your thoughts on this
