                        <li>
                            Start Synapse using the configuration numbered 702 (repository/conf/sample/synapse_sample_702.xml)
                            <div class="command">
                                Unix/Linux: sh synapse.sh -sample 702<br/>
                                Windows: synapse.bat -sample 702

            <subsection name="Executing the Client">
                <p>
                    Execute the sample client a few times with the following command. Note that
                    we still haven't started the sample Axis2 server.
                </p>
                <div class="command">
                    ant stockquote -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dtrpurl=http://localhost:8280/ -Dmode=placeorder
                </div>

                <p>
                    Deploy the SimpleStockQuoteService in the sample Axis2 server and start Axis2.
                </p>
                <p>
                    When you start the service you will see messages getting delivered to the service,
                    even though the service was actually down when we invoked the sample client.
                </p>
                <p>
                    Here in the 'main' sequence store mediator will store the placeOrder request
                    message in the 'MyStore' message store. Message processor will send the message
                    to the endpoint which is configured as a message context property. Message
                    processor will remove the message from the store only if the message is delivered
                    successfully.
