- Start the Synapse configuration numbered 150 (: i.e.
wso2esb-samples.sh -sn 150). - Start the Axis2 server and deploy the
SimpleStockQuoteService if not already done.
...
quote - sends a quote request for a single stock as follows. The response contains the last sales price for the stock which would be displayed.
| Code Block |

|
<m:getQuote xmlns:m="http://services.samples/xsd">
<m:request>
<m:symbol>IBM</m:symbol>
</m:request>
</m:getQuote>
|
customquote - sends a quote request in a custom format. The ESB would transform this custom request into the standard stock quote request format and send it to the service. Upon receipt of the response it would be transformed again to a custom response format and returned to the client, which will then display the last sales price.
