jms adapter and gateway

[charile]

HI,All.

I hava some questions about the jms adpater and gateway.

(1)The jms adapter only supports oneway pattern,not supoorts request/reply pattern .

(2)And the jms gateway only support request/reply pattern,but not supoorts oneway pattern .

I think the jms adapter and gateway both should support oneway and request/reply pattern .But they cannot support oneway and request/reply pattern ,why ?

I am not sure i understand the question.
You use Gateway for by-directional communication
You use Adapter for uni-directional communication.

This is by design.

Yes.you are right.

The JMS Gateway is used for by-directional communication.
The JMS Adapter is used for uni-directional communication.


I have an other question.
why the JMS Gateway cannot be designed for by-directional and uni-directional communications.And the JMS Adapter should by designed for by-directional and uni-directional communications too .

Because the webservice gateway and adapter both support by-directional and uni-directional communications.

So i think the jms gateway and adapter support them too,maybe my idea about this is incorrectness.

Thanks!

There is no adapter in the WS, only gateways (inbound and outbound).
Having said that. . .
You have to look at this from a different perspective.
HTTP interaction is naturally by-directional: request -> response (there is always response)
JMS is always uni-directional: producer -> message -> consumer (there is never a response of any type).
If producer wants to get a reply from the consumer, then producer will become a consumer and consumer will become a producer and process repeats.

And even though we do have just channel-adapters for HTTP (and could for WS), those are just *ignoring* the inevitable response

Ok.

I got it.
