Hi Sergei,
It is returning the correct type ( RechargeRecords ), and this gets handled
via the aspect without any exception (debugged it with my own eyes), but an
exception is getting thrown after the code completion from within the
framework.
/@Path("/fi/rechargeHistory")
public interface RechargeHistoryService {
@GET
@Path("/query/msisdn/{msisdn}")
@Produces("text/xml")
public RechargeRecords query(@PathParam("msisdn") long msisdn,
@QueryParam("fromDate") int fromDate, @QueryParam("toDate")int toDate)
throws PAMSException;
}
