There are a few samples the show using callbacks in the Tuscany samples folder, look for the ones with "callback" in the name. The most recently added is one using the jms binding: http://svn.apache.org/repos/asf/tuscany/java/sca/samples/callbacks-jms, which is based on an INFOQ article about SCA asynchronous programming, see the sample README for details.
