    /**
     * This test will first sends a request to a dummy service deployed. That service will get
     * message contexts as inputs and will put a property in the service group context to count the
     * number of requests.
     * Then the client, upon receiving the response, extracts the sgc id from the received message
     * (this will come as a reference parameter in the ReplyTo EPR) and sets that as a top level
     * soap header in the next request to the same service group.
     * Server will correctly identify the service group from the information sent by the client and
     * retrieve the sgc earlier used and will use that for the current request as well.
     * The service will retrieve the request count from the sgc and increase that by one.
     * <p/>
     * Test will asserts whether the client gets the number of requests as 2, when he invokes two times.
