h1. Exposing a FTP connection as a service
In provide mode, the component expose an external service in the JBI environment to send FTP commands on an FTP server.
The component can expose directly a generic FTP service without deploying a service unit (*Generic mode*) or use a service-unit (*Service-unit mode*).
In generic mode, parameter for the FTP connection are set in the XML message request in a connection node (see [Generic Mode configuration|#GenericModeConfiguration]).
h2. Usage
{info}
* Operation need to be call explicitely in the form : \{service-namespace}operation
Example : \{[http://petals.ow2.org/components/ftp/version-3|http://petals.ow2.org/components/sftp/version-1]}put
* All operations support wild card character
{info}
h3. Put Operation
When the put operation is set on the incoming IN message, the component write the XML message to the FTP 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/ftp/version-3">
<ver:body>xml body</ver:body>
<ver:filename>file name on the FTP 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 FTP 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 FTP 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/ftp/version-3">
<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>
</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 FTP 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 FTP 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/ftp/version-3">
<ver:filename>file name to retrieve</ver:filename>
</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 FTP 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 FTP 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/ftp/version-3">
<ver:filename>file name to retrieve</ver:filename>
</ver:getAsAttachment>
{code}
The OUT message returned to the consumer contains the retrieved file, as attachment:
{code:lang=xml}<?xml version="1.0" encoding="UTF-8"?>
<tns:getAsAttachmentResponse xmlns:tns="http://petals.ow2.org/components/ftp/version-3">
<tns:attachment>
<tns:filename><xop:Include xmlns:xop="http://www.w3.org/2004/08/xop/include" href="cid:test1.xml"/></tns:filename>
</tns:attachment>
</tns:getAsAttachmentResponse>
{code}
The service might return a Fault when an element in the request is missing or if the FTP connection failed
The available exchange pattern is : *InOut*.
h3. MGet Operation
When the mget operation is set on the incoming IN message, the component retrieves files from the FTP server, according to the file names (or filters) set in the XML request.
\\
There is no recursivity, sub folders are ignored.
Each file is set in the OUT message as an attachment. The IN message looks like:
\\
{code:lang=xml}<?xml version="1.0" encoding="UTF-8"?>
<ver:mget xmlns:ver="http://petals.ow2.org/components/ftp/version-3">
<!--1 or more repetitions:-->
<ver:filename>*.xml</ver:filename>
<ver:filename>myFile.txt</ver:filename>
</ver:mget>
{code}
The OUT message returned to the consumer contains files, as attachments:
\\
{code:lang=xml}<?xml version="1.0" encoding="UTF-8"?>
<tns:mgetResponse xmlns:tns="http://petals.ow2.org/components/ftp/version-3">
<tns:attachments>

</tns:attachments>
</tns:mgetResponse>
{code}
The service might return a Fault when an element in the request is missing or if the FTP connection failed
\\
The available exchange pattern is : *InOut*.

server.
The IN message looks like :{code:lang=xml}
<?xml version="1.0" encoding="UTF-8"?><ver:dir xmlns:ver="http://petals.ow2.org/components/ftp/version-3">
</ver:dir>{code}

The available exchange pattern is : InOnly.
h2. Configuration
{anchor:GenericModeConfiguration}
h3. Generic Mode
To allow the component to provide his generic service, the component must have a wsdl with the name : component.wsdl. An example of this file is available in the component.
To deactivate the generic service supplies by the component,simply erase the file : component.wsdl.
To configure the FTP connection in your XML message request, you have to provide a connection element.
\\ {code:lang=xml}
...
<ver:connection>
<ver:server>?</ver:server>
<ver:port>?</ver:port>
<ver:user>?</ver:user>
<ver:password>?</ver:password>
<!--Optional:-->
<ver:folder>?</ver:folder>
<ver:transfer-type>ascii|binary</ver:transfer-type>
<ver:connection-mode>active|passive (optional, default is active)</ver:connection-mode>
<ver:delete-processed-files>true|false(optional, default is active)</ver:delete-processed-files>
<ver:encoding>?</ver:encoding>
</ver:connection>
