h1. Feature
The FileTransfer component is a Binding Component (BC) which supports file transfers.
This component allows to:
* Expose a file system connector as a service which provide a set of 8 operations:
** *put:* Write the received JBI messages in a file with a specified name
** *mput:* Write the JBI message attachments it receives into files.
** *get:* Retrieve *Xml* file corresponding to a pattern, from a folder. Return it as message payload.
** *getAsAttachment:* Retrieve the first file corresponding to a pattern, from a folder. Return it as message's attachment.(XOP standard)
** *mGet:* Retrieve files corresponding to a pattern, from a folder. Return them as message's attachment.
** *checkFile:* Check the availability of a file.
** *del:* Delete one file.
** *dir:* List the content of a folder.
* Poll a configured directory for incoming files. At a poll, each file retrieved is put into a new JBI message, set as source or attachment. The message is sent to a target JBI service.
{info}All attachment are processed by using XOP rules.(XML-binary Optimized Packaging : [http://www.w3.org/TR/xop10/] ){info}

h2. Usage
h3. Put Operation
When the put operation is set on the incoming IN message, the component writes the XML message to the configured directory.
The created file takes the name described in the service unit (filename parameter) otherwise the operation name is taken. For each file created, the system date is appended to this file name.
The IN message looks like :
{code:lang=xml}
<?xml version="1.0" encoding="UTF-8"?>
<ver:put xmlns:ver="http://petals.ow2.org/components/filetransfer/version-3">?</ver:put>
{code}
The service does not return a message.
The available exchange pattern is : *InOnly*.
h3. MPut Operation
When the mput operation is set on the incoming IN message, the component writes the attachments on the configured directory.
The IN message looks like :
{code:lang=xml}
<?xml version="1.0" encoding="UTF-8"?>
<ver:mput>
<ver:attachments xmlns:ver="http://petals.ow2.org/components/filetransfer/version-3">
<!--1 or more repetitions:-->
<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 available exchange pattern is : *InOnly*.
h3. Get Operation
When the get operation is set on the incoming IN message, the component retrieves ONE file from the configured directory 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/filetransfer/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 an IO error occurs.
\\
The available exchange patterns is : *InOut*.
{info}Only xml file could be processed otherwise an error will be raised.{info}
h3. GetAsAttachement Operation
When the getAsAttachment operation is set on the incoming IN message, the component retrieve ONE file from the configured directory according to the filename(or filter) set in the XML request.
The retrieved 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:getAsAttachment xmlns:ver="http://petals.ow2.org/components/ftp/version-3">
<ver:filename>file name to retrieve</ver:filename>
</ver:getAsAttachment>
{code}

</tns:attachment>
</tns:getAsAttachmentResponse>
{code}
The service might return a Fault when an element in the request is missing or if an IO error occurs.
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 configured directory, according to the filenames (or filters) set in the XML request.
