=============================================

Tips To Remember

1. Generating a response inside the proxy service for get request you need to add this property after removing the To header.

<property name="NO_ENTITY_BODY" scope="axis2" action="remove"/>

2. Making of soap-fault generating proxy

<proxy name="Faultproxy"
          transports="https http"
          startOnLoad="true"
          trace="disable">
      <description/>
      <target>
         <inSequence>
            <makefault version="soap11">
               <code xmlns:soap11Env="http://schemas.xmlsoap.org/soap/envelope/"
                     value="soap11Env:VersionMismatch"/>
               <reason value="500"/>
               <role/>
            </makefault>
            <respond/>
         </inSequence>
      </target>
   </proxy>

3. Script mediator to log thread names for wso2 esb each request

<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://ws.apache.org/ns/synapse">
   <localEntry key="stockquoteScript"
               src="file:repository/samples/resources/script/stockquoteTransform.js"/>
   <sequence name="fault">
      <log level="full">
         <property name="MESSAGE" value="Executing default &#34;fault&#34; sequence"/>
         <property name="ERROR_CODE" expression="get-property('ERROR_CODE')"/>
         <property name="ERROR_MESSAGE" expression="get-property('ERROR_MESSAGE')"/>
      </log>
      <drop/>
   </sequence>
   <sequence name="main">
      <in>
         <script language="js" key="stockquoteScript" function="transformRequest"/>
         <send>
            <endpoint>
               <address uri="http://localhost:9000/services/SimpleStockQuoteService"/>
            </endpoint>
         </send>
      </in>
      <out>
         <script language="js" key="stockquoteScript" function="transformResponse"/>
         <log level="custom">
            <property name="Fooo" expression="get-property('threadName')"/>
         </log>
         <send/>
      </out>
   </sequence>
</definitions>


Add a script as a local entry (eg: URL repository/samples/resources/script/stockquoteTransform.js)

* Your stockquoteTransform.js should look like this.

function transformRequest(mc) {
    var symbol = mc.getPayloadXML()..*::Code.toString();
    mc.setPayloadXML(
            <m:getQuote xmlns:m="http://services.samples">
                <m:request>
                    <m:symbol>{symbol}</m:symbol>
                </m:request>
            </m:getQuote>);
}

function transformResponse(mc) {

    mc.setProperty("threadName", java.lang.Thread.currentThread().getName());
    java.lang.Thread.sleep(10000);
}
 
Now open a soapUI and send your soap request to http://localhost:8280/ main sequence.

Now you should be able to see entries displayed in the console of each thread name. Alternatively you can also open the wso2carbon.log file which resides at [CARBON_HOME]/repository/logs to view the thread names generated to handle each request.
