Introduction

This sample demonstrates how you can convert a POX message to a SOAP request.

Prerequisites

For a list of prerequisites, see Prerequisites to Start the ESB Samples.

Building the sample

The XML configuration for this sample is as follows: 

<definitions xmlns="http://ws.apache.org/ns/synapse">
   <sequence name="main">
     <in>
       <!-- filtering of messages with XPath and regex matches -->
       <filter source="get-property('To')" regex=".*/StockQuote.*">
           <header name="Action" value="urn:getQuote"/>
           <send>
               <endpoint>
                   <address uri="http://localhost:9000/services/SimpleStockQuoteService" format="soap11"/>
               </endpoint>
           </send>
       </filter>
     </in>
     <out>
          <send/>
     </out>
   </sequence>
</definitions>

This configuration file  synapse_sample_50.xml is available in the <ESB_HOME>/repository/samples directory.

To build the sample

  1. Start the ESB with the sample 50 configuration. For instructions on starting a sample ESB configuration, see Starting the ESB with a sample configuration.

    The operation log keeps running until the server starts, which usually takes several seconds. Wait until the server has fully booted up and displays a message similar to "WSO2 Carbon started in n seconds."

  2. Start the Axis2 server. For instructions on starting the Axis2 server, see Starting the Axis2 server.

  3. Deploy the back-end service SimpleStockQuoteService. For instructions on deploying sample back-end services, see Deploying sample back-end services.

Executing the sample

The sample client used here is the Stock Quote Client, which can operate in several modes. For further details on this sample client and its operation modes, see Stock Quote Client.

To execute the sample client

  • Run the following command from the <ESB_HOME>/samples/axis2Client directory, specifying that the request should be a REST request.

    ant stockquote -Dtrpurl=http://localhost:8280/services/StockQuote -Drest=true

Analyzing the output

The request sent by the client is as follows:

POST /services/StockQuote HTTP/1.1
Content-Type: application/xml; charset=UTF-8;action="urn:getQuote";
SOAPAction: urn:getQuote
User-Agent: Axis2
Host: 127.0.0.1
Transfer-Encoding: chunked

75
<m0:getQuote xmlns:m0="http://services.samples/xsd">
   <m0:request>
      <m0:symbol>IBM</m0:symbol>
   </m0:request>
</m0:getQuote>0

It is a HTTP REST request, which will be transformed into a SOAP request and forwarded to the stock quote service.
