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}
...
<!--
Note : you must use one of the above authentication modes when
using dynamic configuration (ie using SU configuration)
-->
<!-- When using user / password authentication -->
<ver:connection>
<ver:server>server</ver:server>
<ver:port>port</ver:port>
<ver:user>user</ver:user>
<ver:password>password</ver:password>
<ver:folder>folder</ver:folder>
</ver:connection>
<!-- When using private key authentication -->
<ver:connection>
<ver:server>server</ver:server>
<ver:port>port</ver:port>
<ver:user>user</ver:user>
<ver:password>pathtoprivatekey</ver:password>
<ver:folder>folder</ver:folder>
</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}
<ver:put xmlns:ver="http://petals.ow2.org/components/sftp/version-1.0">
<!-- content to be put on the SFTP server -->
<ver:body>xml body</ver:body>
<!-- Name of the file to be created on the SFTP server -->
<ver:filename>filename</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 patterns are :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}
<ver:mput xmlns:ver="http://petals.ow2.org/components/sftp/version-1.0">
<\!--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 patterns are: 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-1.0">
<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 are: {{InOut}}.
h3. MGet Operation
When the mget operation is set on the incoming IN message, the component retrieves files from the SFTP 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/sftp/version-1.0">
<!--1 or more repetitions:-->
<ver:filename>*.xml</ver:filename>
<ver:filename>myFile.txt</ver:filename>
<!--Optional:-->
<ver:connection>
...
</ver:connection>
</ver:mget>
{code}
The OUT message returned to the consumer contains files, as attachments, and an XML message report:
\\
{code:lang=xml}<?xml version="1.0" encoding="UTF-8"?>
<tns:mgetResponse xmlns:tns="http://petals.ow2.org/components/sftp/version-1.0">
<tns:filename>source.xml</tns:filename>
<tns:filename>source2.xml</tns:filename>
<tns:filename>myFile.txt</tns:filename>
</tns:mgetResponse>
{code}
The service might return a Fault when an element in the request is missing or if the SFTP connection failed.
The available exchange pattern is: *InOut*.
h3. Dir Operation
When the dir operation is set on the incoming IN message, the component returns the file names listed from the SFTP
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/sftp/version-1>
<!--Optional:-->
<ver:connection>
...
</ver:connection>
</ver:dir>{code}
The OUT message returned to the consumer is defined as follow :
{code:lang=xml}<tns:dirResponse xmlns:tns="http://petals.ow2.org/components/sftp/version-1">
<!--Zero or more repetitions:-->
<tns:filename>file1.txt</tns:filename>
<tns:filename>linux.jpg</tns:filename>
</tns:dirResponse>
{code}
The service might return a Fault when an element in the request is missing or if the SFTP connection failed
The available exchange pattern is : *InOut*.
h2. Configuration
{note:title=Put XML content or send SFTP commands to the SFTP server}
PROVIDE SERVICE : Expose an external service in the JBI environment to put XML messages or send SFTP commands on an SFTP server
Petals SFTP binding component allows JBI consumers to send XML messages to an SFTP server. A JBI endpoint is registered into the JBI environment, and is linked to an SFTP server, with a configured user/password. When the SFTP component receives a message exchange from Petals platform, the XML content of the message is put on the SFTP server.
The component can also provide a generic SFTP service. This service allows the consumer to call SFTP commands. This service can either connects to an SFTP server configured in the ServiceUnit, or retrieves the SFTP server information in the XML message request.
To use this generic service, the consumer has to call explicitely the \{service namespace}get/mget/put/mput/dir operations.
{note}
h3. Service Unit descriptor
The service unit is configurable via its extensions in the jbi.xml file:
Excample of a Service Unit descriptor to provide a SFTP service:
{code:lang=xml}
<?xml version="1.0" encoding="UTF-8"?>
<!--
