How to invoke REST services cross servers in Jazz?

Hi all,

I would like to invoke a REST service cross servers in Jazz platform. As far as I know, I can build up a HTTP request and send it to the remote REST service from our local service via HTTP connection. Is there any other approach to do this invocation like as RPC way?

For example, at server A, I have my customized service named "Invoker" and it tries to invoke a service that is on server B and named "MyRESTService". Beside sending a HTTP request which makes up request parameters and URI of "MyRESTService" into it, do we have other way like a remote procedure call way to invoke this remote service?

Any instruction and samples are very appreciated!
