h1. Exposing a SFTP connection as a service
In provide mode, the component expose an external service in the JBI environment to send SFTP commands on an SFTP server.
This service can either connects to an SFTP server configured in the ServiceUnit, or retrieve the SFTP server information in the XML message request (*Dynamic mode*).
\\
h2. Usage
When using the SFTP service, you can optionnaly define the SFTP connection information in your XML request. If you don't, the service unit parameters are used.
To configure the SFTP connection in your XML message request, you have to provide a connection element.
\\ {code:lang=xml}

<!--Optional:-->
<ver:connection>
<ver:server>?</ver:server>
<ver:port>?</ver:port>
<ver:user>?</ver:user>
<!--Optional:-->
<ver:password>?</ver:password>
<ver:folder>?</ver:folder>
<ver:passphrase>?</ver:passphrase>

</ver:connection>
...
{code}
{info}Operation need to be call explicitely in the form : \{service-namespace}operation
Example : \{[http://petals.ow2.org/components/sftp/version-1]}put{info}
h3. Put Operation
When the put operation is set on the incoming IN message, the component write the XML message to the SFTP server.
\\
The IN message looks like :
{code:lang=xml}<?xml version="1.0" encoding="UTF-8"?>
<ver:put xmlns:ver="http://petals.ow2.org/components/sftp/version-1">
<ver:body>xml body</ver:body>
<ver:filename>file name on the server</ver:filename>
<!--Optional:-->
<ver:connection>
...
</ver:connection>
</ver:put>
{code}
The service does not return a message.
The service might return an error when an element in the request is missing or if the SFTP connection failed.
The available exchange pattern is : *InOnly*.
\\
h3. MPut Operation
When the mput operation is set on the incoming IN message, the component write the attachments on the SFTP server.
The IN message looks like :
{code:lang=xml}<?xml version="1.0" encoding="UTF-8"?>
<ver:mput xmlns:ver="http://petals.ow2.org/components/sftp/version-1">
<ver:attachments>
<ver:filename><xop:Include xmlns:xop="http://www.w3.org/2004/08/xop/include" href="cid:test1.xml"/></ver:filename>
<ver:filename><xop:Include xmlns:xop="http://www.w3.org/2004/08/xop/include" href="cid:test2.xml"/></ver:filename>
</ver:attachments>
<!--Optional:-->
<ver:connection>
...
</ver:connection>
</ver:mput>
{code}
The service does not return a message.
\\
The service might return an error when an element in the request is missing or if the SFTP connection failed.
The available exchange pattern is : *InOnly*.
\\
h3. Get Operation
When the get operation is set on the incoming IN message, the component retrieve ONE file from the SFTP server and return it as an XML message content.
\\
The name of the file to retrieve is set in the XML IN content of the message.
\\
The IN message looks like :
\\
{code:lang=xml}<?xml version="1.0" encoding="UTF-8"?>
<ver:get xmlns:ver="http://petals.ow2.org/components/sftp/version-1">
<ver:filename>file name to retrieve</ver:filename>
<!--Optional:-->
<ver:connection>
...
</ver:connection>
</ver:get>
{code}
The OUT message returned to the consumer is the content of the XML file
\\
The service might return a Fault when an element in the request is missing or if the SFTP connection failed
\\
The available exchange patterns is : *InOut*.
{info}Only xml file could be processed otherwise an error will be raised.{info}
h3. GetAsAttachment Operation
When the get operation is set on the incoming IN message, the component retrieve ONE file from the SFTP server and return it as an attachment.
The name of the file to retrieve is set in the XML IN content of the message.
The IN message looks like :
{code:lang=xml}<?xml version="1.0" encoding="UTF-8"?>
<ver:getAsAttachment xmlns:ver="http://petals.ow2.org/components/sftp/version-1">
<ver:filename>file name to retrieve</ver:filename>
<!--Optional:-->
<ver:connection>
...
</ver:connection>
</ver:getAsAttachment>
{code}
The OUT message returned to the consumer contains files, as attachments, and an XML message report :
