Sample 352: Accessing the Synapse MessageContext API Through Scripts
<definitions xmlns="http://ws.apache.org/ns/synapse">
<sequence name="main">
<in>
<!-- change the MessageContext into a response and set a response payload -->
<script language="js">
mc.setTo(mc.getReplyTo());
mc.setProperty("RESPONSE", "true");
mc.setPayloadXML(
<ns:getQuoteResponse xmlns:ns="http://services.samples/xsd">
<ns:return>
<ns:last>99.9</ns:last>
</ns:return>
</ns:getQuoteResponse>);
</script>
</in>

</sequence>
</definitions>
Objective
Demonstrate how to access various methods on the Synapse MessageContext API
using the script mediator
Executing the Client
This example shows how an inline JavaScript can access the Synapse message context
API to set its 'To' EPR and to set a custom property to mark it as a response. Execute
the stock quote client, and you will receive the response '99.9' as the last sale
price as per the above script.
ant stockquote -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dtrpurl=http://localhost:8280/
Note that the symbol 'mc' is bound to the Synapse MessageContext object by the
script mediator. Then the user can invoke various methods on the message context
using common JavaScript syntax such as mc.getProperty('name') and mc.setTo('epr').
