WSO2 ESB | VFS to Service Mediation

Question

I want to read a set of files from FTP server and then pass it to my service for transformation and then sent the transformed file to be written to the output folder via VFS. I configured the VFS protocol and also configured the endpoint. Please see below the configurations:

<?xml version="1.0" encoding="UTF-8"?>
    <proxy xmlns="http://ws.apache.org/ns/synapse"
           name="FileSystemVFSProxy"
           transports="https,http,local,vfs"
           statistics="disable"
           trace="disable"
           startOnLoad="true">
       <target>
          <inSequence>
             <log level="full"/>
             <send>
                <endpoint>
                   <address uri="http://localhost:8280/services/EDIMessenger" format="soap11"/>
                </endpoint>
             </send>
          </inSequence>
          <outSequence>
             <property name="transport.vfs.ReplyFileName"
                       value="test.xml"
                       scope="transport"
                       type="STRING"/>
             <property name="OUT_ONLY" value="true"/>
             <send>
                <endpoint>
                   <address uri="vfs:file:///D:/WSO2"/>
                </endpoint>
             </send>
          </outSequence>
       </target>
       <parameter name="transport.PollInterval">15</parameter>
       <parameter name="transport.vfs.ActionAfterProcess">MOVE</parameter>
       <parameter name="transport.vfs.FileURI">file:///D:/WSO2/content</parameter>
       <parameter name="transport.vfs.MoveAfterProcess">file:///D:/WSO2/original</parameter>
       <parameter name="transport.vfs.MoveAfterFailure">file:///D:/WSO2/Archive</parameter>
       <parameter name="transport.vfs.FileNamePattern">.*\.*</parameter>
       <parameter name="transport.vfs.ContentType">text/plain</parameter>
       <parameter name="transport.vfs.ActionAfterFailure">MOVE</parameter>
       <description/>
    </proxy>

The service configuration is as below:

<?xml version="1.0" encoding="UTF-8"?>
<serviceGroup name="EDIMessengerEx_1.0.0"
              hashValue="74dc0f1e0e5cef0a5d78d09dc7f0edb1"
              successfullyAdded="true">

   </service>
</serviceGroup>

When I am trying this, I am getting the below exception:

Any suggestions on what I may be doing wrong would be highly appreciated.

Answer 1

Please check the link below for testing your simple VFS file processing. The sample will read the data from a file, process each line inside sequence, and then move the process file into a predefined folder.

Answer 2

replace the localhost with the ip address of your machine, this should work if the service is up and running
