SOAP over JMS

SOAP webservices can be accessed through HTTP  as well as JMS .
SOAP over JMS  gives message delivery guarantee and is  preferred where  message critical application  are deployed.


JMS provide two types of message communication


1) point to point
    (A) once message is received it is removed from Q
    (B) only one receiver can receive the message
2) publish / subscribe
    (A) message stays on topic even after one receiver reads it
    (B) multiple receivers can subscribe to same topic 




JMS webservices can be  developed  with two approaches


1) 1 way request
- web client will get unblock once  the request is  gone to destination  (Q/Topic)
- Q/Topic both can implement it
2) request - response
- web client will get unblock only after response gets back to the client
-Only Q can implement this type of web service
