  1. Download and install WSO2 ESB from http://wso2.com/products/enterprise-service-bus. For a list of prerequisites and step-by-step installation instructions, refer to Getting Started Installation Guide in the WSO2 ESB documentation.
  2. Start the sample Axis2 server. For instructions, refer to the section Setting Up the ESB Samples Setup - Starting Sample Back-End Servicesthe Axis2 server in the WSO2 ESB documentation.

In the management console, navigate to the Main Menu, click Service Bus and then Source View menu and click Source View in the Service Bus section. Next, copy and paste the following configuration, which helps you explore the example scenario, to the source view.

  1. Send the following request using a SOAP client like SoapUI, and monitor the message using TCPMon.
     

    Code Block
    languagehtml/xml
    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://services.samples" xmlns:xsd="http://services.samples/xsd">
   <soapenv:Header/>
   <soapenv:Body>
      <ser:getQuote>     
         <ser:request>           
            <xsd:symbol>Foo<symbol>foo</xsd:symbol>
         </ser:request>        
      </ser:getQuote>
   </soapenv:Body>
</soapenv:Envelope>

  2. Notice that the request data is inside a SOAP envelope. When the request was monitored through TCPMon before it was sent to the ESB, it was structured as follows:

    Code Block
    POST /services/EnvelopeUnwrapProxy HTTP/1.1 
Accept-Encoding: gzip,deflate 
Content-Type: text/xml;charset=UTF-8 
SOAPAction: "urn:getQuote" 
Content-Length: 385 
Host: 127.0.0.1:8281 
Connection: Keep-Alive 
User-Agent: Apache-HttpClient/4.1.1 (java 1.5) 
 
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://services.samples" xmlns:xsd="http://services.samples/xsd">
   <soapenv:Header/>
   <soapenv:Body>
      <ser:getQuote>     
         <ser:request>           
            <xsd:symbol>Foo<symbol>foo</xsd:symbol>
         </ser:request>        
      </ser:getQuote>
   </soapenv:Body>
</soapenv:Envelope>

  3. The request sent to the back-end Axis2 server has the following structure:

    Code Block
    POST /services/SimpleStockQuoteService HTTP/1.1 
Content-Type: application/xml; charset=UTF-8 
Accept-Encoding: gzip,deflate 
SOAPAction: urn:getQuote 
Transfer-Encoding: chunked 
Host: localhost:9000 
Connection: Keep-Alive 
User-Agent: Synapse-HttpComponents-NIO 
 
e0 
<ser:getQuote xmlns:ser="http://services.samples">     
         <ser:request>           
            <xsd:symbol xmlns:xsd="http://services.samples/xsd">Foo<>foo</xsd:symbol>
         </ser:request>        
      </ser:getQuote> 
0

    This means that the SOAP envelope was removed by the ESB.
