h1. Component Configuration

The following attributes can be set during the installation phase to configure the component, using the params element of the jbi-install-component ANT task:


h2. Configuration of the component (CDK)

\\
{include:0 CDK Component Configuration Table}


{include:0 CDK Parameter scope}

h1. Service Configuration

{include:0 CDK SU Provide Configuration}

h2. PROVIDE SERVICE : Expose an external service in the JBI environment to send FTP commands on an FTP server


Petals FTP binding component allows JBI consumers to call FTP command. A JBI endpoint is registered into the JBI environment, and is linked to an FTP server, with a configured user/password.To use this service, the consumer has to call explicitely the *{service* *namespace{*}*}get/mget/put/mput/dir/del* operations.When the FTP component receives a message exchange from Petals platform, it call the FTP command associate with the jbi operation.

This service can either connects to an FTP server configured in the ServiceUnit, or retrieve the FTP server information in the XML message request.
\\
\\

h3. Service Unit descriptor



The service unit is configurable via its extensions in the jbi.xml file:
\\
{code:lang=xml}<?xml version="1.0" encoding="UTF-8"?>
<!-- JBI descriptor for PEtALS' "petals-bc-ftp" (FTP), version 3.0 -->

h3. Service Unit content&nbsp;



The Service Unit has to contain the following elements, packaged in an archive:
\\
* The META-INF/jbi.xml descriptor file, has described above,
* An optional wsdl file describing the related service

{code}service-unit.zip
+ META-INF
    - jbi.xml (as defined above)
    - service.wsdl (optional)
{code}

h3. FTP Service



\\
The petals-bc-ftp component provides 5 operations, when using the Ftp service:
\\
* *put* : copy incoming XML message on the FTP server
* *mput* : copy incoming message attachments on the FTP server
* *get* : get one specified file from the FTP server and return it as an XML message
* *mget* : get files from the FTP server and return them as attachments
* *dir* : return the files list on the FTP server
* *del* : remove file on the FTP server

When using the FTP service, you can optionnaly define the FTP connection information in your XML request. If you don't, the service unit parameters are used.
\\
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>

h4. 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*.
\\

h4. 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:attachments>
<!--Optional:-->
<ver:connection>
...
</ver:connection>
</ver:mput>
{code}

The available exchange pattern is : *InOnly*.
\\

h4. 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.
\\

...
</ver:connection>
</ver:get>
{code}

h4. 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"?>
