WSO2 Smook response not write to file - esb

Question

I'm trying write the response from a proxy with Smooks Mediator on a file but nothing happens.
The mediator get a csv file with vfs option, convert to xml output and send the csv to a out directory correctely.
In console i see the ws02-esb-service.log and the xml is correctly.
But i not do get write to file.
In /u01/app/wso2esb-4.7.0/tmp/send/convert then result not appears.
And not have any error.
This is the code.
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
name="SmookTest"
transports="vfs"

Answer 1

Since the VFS read as a plain/text format it will not engage the formarter until you explicitly mention it. Therefore you can mention the content type before you call the endpoint
Like
<property name="OUT_ONLY" value="true"/>
<property name="messageType"
value="application/soap"
scope="axis2"
type="STRING"/>
<send>
<endpoint name="grabar">
<address uri="vfs:file:///u01/app/wso2esb-4.7.0/tmp/send/convert"/>
</endpoint>
</send>

Answer 2

I found the solution.
adding format to endpoint and the file content are write correctly.
<address uri="vfs:file:///u01/app/wso2esb-4.7.0/tmp/send/convert"
format="soap11"/>
