            <subsection name="Pre-requisites">
                <p>
                    <ul>
                        <li>
                            Start two instances of sample Axis2 server on HTTP ports 9000,9001. And deploy the SimpleStockQuoteService in all of them.
                        </li>
                        <li>
                            Start Synapse using the configuration numbered 854 (repository/conf/sample/synapse_sample_854.xml)
                            <div class="command">
                                Unix/Linux: sh synapse.sh -sample 854<br/>
                                Windows: synapse.bat -sample 854

            <subsection name="Executing the Client">
<p>
In this sample, the messages sent to Synapse will be route to a secondary channel(wiretap_uri) while they are being forwarded to the main channel(destination_uri).
</p> 
<p>
                    Invoke the client as follows.
                </p>
                <div class="command">ant stockquote -Dtrpurl=http://localhost:8280/</div>
