request-response via JMS from service

[davison]

hi,

I'm struggling to find an example of a pattern I thought would be obvious (so I expect I'm looking in the wrong places!).

I want to basically do the inverse of the gateway examples (channel -> service pojo -> channel). From a service tier object, I want to perform a blocking method call where the parameter is sent as a message on a JMS queue and the message that turns up on the reply queue is the return value from the method call. i.e.

public interface MyService {
    String someServiceMethod(String input);
}

with SI providing an implementation of that interface which effectively does "input -> channel -> broker -> reply-channel -> method return"

I can see how I can do this with a jms:outbound-gateway, but not without directly depending on the SI API.

Any pointers to an example of this?

Cheers,

We chatted about this on #spring I think. Did that solve your problem?

hi Iwein - yes, the gateway did work, and I did manage to make it work through the dynamic proxy implementation too (i.e. not depending on SI API's in the code). Thanks for your time

[iwein]

So when is that blog due comparing SI and Camel

Could you please attach the gateway sample configuration to this thread?

Thanks a lot,

I believe they were referring to the JMS gateway sample that is included in the Spring Integration distribution (or SVN).

You can find the samples here:
