Publish-Subscribe how to get client(consumer) to send messages

[arthurportas]

Hi,

I'm developing a program using Publish-Subscribe and i want to know how to get client(consumer) to send messages(response) to server.

I know thack i can have acknoledge messages, but i need to send messages to server, to represent a sort of quizz scenario.

Do i need two topics, and sync them on server -side?

Thanks

I think what you are trying to do here is JMS Request/Reply. Have a look at  http://fusesource.com/docs/broker/5.5/explore_jms/ExploreJMSReqReply.html as it will allow you to send a request and wait for a synchronous response.

If you need to aggregate several responses before send the message back to the producer then have a look at FUSE Mediation Router (based on Apache Camel) and its Aggregator component ( http://fusesource.com/docs/router/2.8/eip/MsgRout-Aggregator.html )

Hope this helps,

-Marcelo

Hi, thanks for the reply.

What i'm trying to develop is a scenario similar to the 'Who whantst to be a millionaire' and publish questions that clients can reply using publish-subscribe.

I don't think Request and Reply is suitable.

Perhaps, both sides, server and client acting as producer/consumer?
