                    Demonstrate how to schedule tasks to invoke a named sequence periodically using

                    <ul>
                        <li>
                            Deploy the SimpleStockQuoteService in the sample Axis2 server and start Axis2
                        </li>
                        <li>
                            Start Synapse using the configuration numbered 301 (repository/conf/sample/synapse_sample_301.xml)
                            <div class="command">
                                Unix/Linux: sh synapse.sh -sample 301<br/>
                                Windows: synapse.bat -sample 301
                            </div>
                        </li>
                    </ul>
                </p>
            </subsection>
            <subsection name="Executing the Client">
                <p>
                    The above configuration adds a scheduled task and sequences to the Synapse runtime.
                    The task is configured to run every 5 seconds (note the 'interval' attribute on
                    the 'trigger' element).
                </p>
                <p>
                    In this sample, the sequence "SampleSequence" will be invoked by the task and
                    then from the sequence, the injected messages will be sent to the sample Axis2
                    server, which will send back a response to Synapse. So every 5 seconds you will
                    notice that Axis2 is generating a quote and Synapse is receiving the stock quote
                    response. You will also see "SampleSequence invoked" message getting logged on
                    the console.
