Use mail transport in ESB to convert the SOAP message to a plain text mail

Scenario:
Imagine a scenario where you are using the mail transport in ESB. You need to convert the SOAP message to a plain text mail(without any XML in it). This blogpost is written to address it.

How To:
Following steps will guide you to get your scenario up and running.

1) Uncomment the mail TransportSender and TransportReceiver from axis2.xml

<transportSender name="mailto" class="org.apache.axis2.transport.mail.MailTransportSender">
   <parameter name="mail.smtp.host">smtp.gmail.com</parameter>
   <parameter name="mail.smtp.port">587</parameter>
   <parameter name="mail.smtp.starttls.enable">true</parameter>
   <parameter name="mail.smtp.auth">true</parameter>
   <parameter name="mail.smtp.user">synapse.demo.0</parameter>
   <parameter name="mail.smtp.password">mailpassword</parameter>
   <parameter name="mail.smtp.from">synapse.demo.0@gmail.com</parameter>
</transportSender>

<transportReceiver name="mailto" class="org.apache.axis2.transport.mail.MailTransportListener">
</transportReceiver>

2) Add the following line to axis2.xml's MessageFormatters.

<messageFormatter contentType="text/plain" class="org.apache.axis2.format.PlainTextFormatter"/>

3) Build the SimpleStockQuote service (which is residing inside the samples). Run sample axis2Server.

4) Use the attached proxy configuration.

<!-- Using the mail transport -->
<definitions xmlns="http://ws.apache.org/ns/synapse">
 <proxy name="StockQuoteProxy" transports="mailto">

     <parameter name="transport.mail.Address">synapse.demo.1@gmail.com</parameter>
     <parameter name="transport.mail.Protocol">pop3</parameter>
     <parameter name="transport.PollInterval">5</parameter>
     <parameter name="mail.pop3.host">pop.gmail.com</parameter>
     <parameter name="mail.pop3.port">995</parameter>
     <parameter name="mail.pop3.user">synapse.demo.1</parameter>
     <parameter name="mail.pop3.password">mailpassword</parameter>
     <parameter name="mail.pop3.socketFactory.class">javax.net.ssl.SSLSocketFactory</parameter>
     <parameter name="mail.pop3.socketFactory.fallback">false</parameter>
     <parameter name="mail.pop3.socketFactory.port">995</parameter>
     <parameter name="transport.mail.ContentType">application/xml</parameter>

     <target>
         <inSequence>
             <property name="senderAddress" expression="get-property('transport', 'From')"/>
             <log level="full">
                 <property name="Sender Address" expression="get-property('senderAddress')"/>
             </log>

             <send>
                 <endpoint>
                     <address uri="http://localhost:9000/services/SimpleStockQuoteService"/>
                 </endpoint>
             </send>
         </inSequence>
         <outSequence>
             <property name="Subject" value="Custom Subject for Response" scope="transport"/>
       <property name="messageType" value="text/plain" scope="axis2-client"/>
<script language="js"><![CDATA[
               mc.setPayloadXML(<ns:text xmlns:ns="http://ws.apache.org/commons/ns/payload">Plain text received!</ns:text>);
    ]]></script>
             <header name="To" expression="fn:concat('mailto:', get-property('senderAddress'))"/>
             <log level="full">
                 <property name="message" value="Response message"/>
                 <property name="Sender Address" expression="get-property('senderAddress')"/>
             </log>
             <send/>
         </outSequence>
     </target>
     <publishWSDL uri="file:repository/samples/resources/proxy/sample_proxy_1.wsdl"/>
 </proxy>
</definitions>

5) Send an email to synapse.demo.1@gmail.com

6) You will receive the response in plain text.
