Writing a Mock Service using WSO2 ESB

The following is WSO2 ESB configuration which will allow sending a mock response back to its caller.

<proxy xmlns="http://ws.apache.org/ns/synapse"
      name="testMockService"
      transports="https,http"
      statistics="disable"
      trace="disable"
      startOnLoad="true">
  <target>
     <inSequence>
        <log level="custom">
           <property name="MockService" value="Service Invoked"/>
        </log>
        <log level="full"/>
        <payloadFactory>
           <format>
               <response>
                    <response1>Sample Test Response</response1>
                    <info>http://www.wso2.com</info>
                 </response>
           </format>
           <args/>
        </payloadFactory>
        <header name="To" action="remove"/>
        <property name="RESPONSE" value="true" scope="default" type="STRING"/>
        <property name="NO_ENTITY_BODY" scope="axis2" action="remove"/>
        <send/>
     </inSequence>
  </target>
  <description/>
</proxy>

Note the following characteristics of the configuration,


      <payloadFactory>
           <format>
               <response>
                    <response1>Sample Test Response</response1>
                    <info>http://www.wso2.com</info>
                 </response>
           </format>
           <args/>
        </payloadFactory>


The above configuration snippet will allow constructing a new payload which should be sent, the xml elements listed between the <format/> tag will construct the new payload.

Note the following three properties,


        <header name="To" action="remove"/>
        <property name="RESPONSE" value="true" scope="default" type="STRING"/>
        <property name="NO_ENTITY_BODY" scope="axis2" action="remove"/>

The above will allow the message to be set back to be transmitted to the caller who sent the message,

using the <send /> will result in sending the constructed message back to the caller.
