Sample 900: Inbound Endpoint File Protocol Sample (VFS)

Objective: Using the file system as input medium using inbound file listener.

Prerequisites

Start the Axis2 server and deploy the SimpleStockQuoteService if not already done
Create three new directories in a test directory, for example, in, out, original in /home/user/test. Open ESB_HOME/repository/samples/synapse_sample_900.xml and edit the following values. Change transport.vfs.FileURI, transport.vfs.MoveAfterProcess, transport.vfs.MoveAfterFailure parameter values to the above in, original, original directories respectively.
Start the Synapse configuration numbered 900: wso2esb-samples.sh -sn 900
Copy ESB_HOME/repository/samples/resources/vfs/test.xml to the directory given in transport.vfs.FileURI above.

test.xml file content is as follows:

<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsa="http://www.w3.org/2005/08/addressing">
    <soapenv:Body>
    	<m0:getQuote xmlns:m0="http://services.samples"> 
        	<m0:request>
            	<m0:symbol>IBM</m0:symbol>
            </m0:request>
        </m0:getQuote>
    </soapenv:Body>
</soapenv:Envelope>

VFS transport listener will pick the file from in directory and send it to the Axis2 service. The request XML file will be moved to original directory. The response from the Axis2 server will be saved to out directory.
