For Java, have a look at vertx-proton which builds on top of proton-j and is a bit more intuitive (still not great) than proton-j for creating servers and clients. :)

Example “blocking” client https://github.com/EnMasseProject/enmasse/blob/master/amqp-u... , but might give an idea of how to set “dynamic source” required for rpc.

In general though I think the Qpid python and c++ examples might be better.
