"WSO2 ESB has a feature rich file transport which is known as the VFS transport. This transport is currently used by lot of customers for implementing various file transfer and processing scenarios. VFS transport uses the versatile Apache Commons-VFS[1] library as the underline library for various file system related operations. This library provided a rich set of features which allows WSO2 ESB's VFS transport to connect to various types of remote file systems. " [1]
The VFS transport implementation is based on Apache Commons VFS implementation.

Lets try a sample.

Start the Axis2 server and deploy the SimpleStockQuoteService if not already done
You will have to modify the following locations accordingly. Create required folders (in,original,failure) and provide the path.

  <parameter name="transport.vfs.FileURI"></parameter> 
<parameter name="transport.vfs.MoveAfterProcess"></parameter>  
<parameter name="transport.vfs.MoveAfterFailure"></parameter> 
Use the following proxy service.

<proxy xmlns="http://ws.apache.org/ns/synapse" name="StockQuoteProxy2" transports="vfs" statistics="disable" trace="disable" startOnLoad="true">
   <target>
      <inSequence>
         <send>
            <endpoint>
               <address uri="http://localhost:9000/services/SimpleStockQuoteService" format="soap12" />
            </endpoint>
         </send>
      </inSequence>
      <outSequence>
         <property name="OUT_ONLY" value="true" />
         <send>
            <endpoint>
               <address uri="vfs:file:///home/achala/supportweek10/failure" />
            </endpoint>
         </send>
      </outSequence>
   </target>
   <parameter name="transport.vfs.ActionAfterProcess">MOVE</parameter>
   <parameter name="transport.PollInterval">10</parameter>
   <parameter name="transport.vfs.MoveAfterProcess">file:///home/achala/supportweek10/original</parameter>
   <parameter name="transport.vfs.FileURI">file:///home/achala/supportweek10/in</parameter>
   <parameter name="transport.vfs.MoveAfterFailure">file:///home/achala/supportweek10/failure</parameter>
   <parameter name="transport.vfs.FileNamePattern">.*.xml</parameter>
   <parameter name="transport.vfs.ContentType">text/xml</parameter>
   <parameter name="transport.vfs.ActionAfterFailure">MOVE</parameter>
</proxy>

Uncomment the VFS transport listener and sender (In the axis2.xml ) . Copy a file to the in folder.
