Answer Posted / maanya shree
pub/sub ? Publish/Subscriber
Publish/Subscriber can have multiple Publisher who publish message and multiple Subscriber who subscribe the messages. This is like watching TV multiple channel and multiple users .
One message can have more then one subscriber.
All the publish messages have the header and subscriber consume the message based on the header.
In JMS we say Topic.
P2p ? Point to point
One message have only one subscriber. Multiple publisher can send multiple messages to the Queue but each message has only one subscriber.
What is the different between JMS and RPC? view answer
RPC : Remote procedure Call
In RPC the method invoker waits for the method to finish execution and return the control back to the invoker. Thus it is completely synchronous in nature.
JMS : Java Messaging System
While in JMS the message sender just sends the message to the destination and continues it's own processing. The sender does not wait for the receiver to respond. This is asynchronous behavior.
