| <subsection name="Objective"> |
| <p> |
| Demonstrating how makefault mediator can be used to construct custom SOAP |
| faults and change the direction (in/out) of messages. |
| </p> |
| </subsection> |
| <subsection name="Pre-requisites"> |
| <p> |
| <ul> |
| <li> |
| Start Synapse using the configuration numbered 5 (repository/conf/sample/synapse_sample_5.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 5<br/> |
| Windows: synapse.bat -sample 5 |
| </div> |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the Client"> |
| <p> |
| When the MSFT stock quote is requested, an unknown host exception would be |
| generated. A connection refused exception would be generated for the SUN stock |
| request. These errors are captured and returned to the original client as a SOAP |
| fault in this example. |
| </p> |
| <div class="command">ant stockquote -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dtrpurl=http://localhost:8280/ -Dsymbol=MSFT</div> |
| <p>returns,</p> |
| <div class="consoleOutput"><soapenv:Fault xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> |
| <faultcode>soapenv:Client</faultcode> |
| <faultstring>java.net.UnknownHostException: bogus</faultstring> |
| <detail /> |
| </soapenv:Fault></div> |
| <p>And </p> |
| <div class="command">ant stockquote -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dtrpurl=http://localhost:8280/ -Dsymbol=SUN</div> |
| <p>returns, </p> |
| <div class="consoleOutput"><soapenv:Fault xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> |
| <faultcode>soapenv:Client</faultcode> |
| <faultstring>java.net.ConnectException: Connection refused</faultstring> |
| <detail /> |
| </soapenv:Fault></div> |
| <p> |
| Note that the response attribute is set to 'true' on the makefault mediator. |
| This instructs the mediator to change the direction of messages to 'response' |
| as messages are transformed into SOAP faults. |
