How to test the Force HTTP 1.0 outgoing messages via WSO2 ESB and a REST request

There are few HTTP transport-specific properties in ESB.

Properties use in ESB access various types of information regarding a message that passes through the ESB. Also properties can be used to control the behavior of the ESB on a given message.

WSO2 ESB support HTTP 1.1 outgoing messages by default. To make it HTTP 1.0, there is a property that would help to perform it.
 

      <property name="FORCE_HTTP_1.0" value="true" scope="axis2"/>  

http://docs.wso2.org/wiki/display/ESB470/HTTP+Transport+Properties

By the following steps I will be explaining how to test this behavior if WSO2 ESB.

Download WSO2 ESB, http://wso2.com/products/enterprise-service-bus

To Setup :
----------------

1. Go to <ESB_Home>/samples/axis2Server/src/SimpleStockQuoteService and build it, ant
   
   
2. Start the Go to <ESB_Home>/samples/axis2Server and start the axis2Server by the following command, sh axis2server.sh.
   
   
3. Start the ESB Server, <ESB_Home>/bin by providing, sh wso2server.sh.
   
   
4. Run a tcpMon to view the outgoing messages.
   
   
5. Start the tcpmon in the <ESB_Home>/bin - sh tcpmon.sh
   Create 2 listeners as below. 
   
   
   1. Listen Port 8281, Target host – localhost, Target port – 8280 – Before hits the ESB
   2. Listen Port 9001, Target host – localhost, target port – 9000 – After passing through ESB and Before hits the backend

6. Log in to the ESB and provide the following synapse configuration.
   
   
   
   

    <?xml version="1.0" encoding="UTF-8"?>  
    <definitions xmlns="http://ws.apache.org/ns/synapse">  
      <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">  
       <header name="Action" value="urn:getQuote"/>  
       <filter source="get-property('To')" regex=".*/StockQuote.*">  
        <property name="FORCE_HTTP_1.0" value="true" scope="axis2"/>  
         <send>  
          <endpoint>  
            <address uri="http://localhost:9001/services/SimpleStockQuoteService"  
                format="soap11"/>  
          </endpoint>  
         </send>  
         <drop/>  
       </filter>  
       <send/>  
      </sequence>  
    </definitions>  
   

To Send the Rest request :

---------------------------------------------

1. Go to axis2Client, <ESB_Home>/samples/axis2Client and send the following REST request.

 ant stockquote -Dtrpurl=http://localhost:8281/services/StockQuote -Drest=true  

Observations :
-------------------------

1. On the server side, Standard :: Stock price = $157.06490695255485 will be generated.
2. Observe the tcpMon.

Rest request sent to ESB can be seen in port 8281,

POST /services/StockQuote HTTP/1.1

Outgoing message from ESB can be seen in port 9001,

POST /services/SimpleStockQuoteService HTTP/1.0
