As the Callout Mediator performs a blocking call, it cannot use the default non-blocking http/s transports based on Java NIO. Therefore, it defaults to using the samples/axis2Client/client_repo/conf/axis2.xml as the Axis2 configuration and samples/axis2Client/client_repo as the client repository unless these are specified separately

<callout serviceURL="http://localhost:9000/services/SimpleStockQuoteService"
action="urn:getQuote">
<source xmlns:s11="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:s12="http://www.w3.org/2003/05/soap-envelope"
xpath="s11:Body/child::*[fn:position()=1] | s12:Body/child::*[fn:position()=1]"/>
<target xmlns:s11="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:s12="http://www.w3.org/2003/05/soap-envelope"
xpath="s11:Body/child::*[fn:position()=1] | s12:Body/child::*[fn:position()=1]"/>
</callout>
|
In this example, the Callout Mediator does the direct service invocation to the StockQuoteService using the client request, get the response and set it as the first child of the SOAP message body. Then using the Send Mediator, the message is sent back to the client.
