1.	What Are The Extra Features Are Available In Ems Apart From Jms?
Answer» The JMS STANDARD specifies TWO delivery modes for messages, PERSISTENT and NON_PERSISTENT. EMS also includes a RELIABLE_DELIVERY mode that eliminates some of the overhead associated with the other delivery modes. For consumer sessions, you can specify a NO_ACKNOWLEDGE mode so that consumers do not need to acknowledge RECEIPT of messages, if desired. EMS also provides an EXPLICIT_CLIENT_ACKNOWLEDGE and EXPLICIT_CLIENT_DUPS_OK_ACKNOWLEDGE mode that restricts the acknowledgement to single messages. EMS extends the Map Message and Stream Message body types. These extensions allow EMS to EXCHANGE messages with TIBCO Rendezvous and Active Enterprise formats that have certain features not available within the JMS Map Message and Stream Message.
