Well some of the naming conventions are confusing dear..like namespace is having Asynchronous in it,
Anyway, please check the following:
1. Sender side cc needs to have Best Effort
2. Try with receiver DT, MT, MI name as Response_Your_Request_MT so it could be Response_JDCB_Sen_MT (For exact please check the SAP documention for the JDBC receiver/sender adapter)
