h1. Feature
The FTP component is a Binding Component (BC) which supports FTP command.
This component provide a set of 5 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.
These operations are available in two modes:
* through a service provider implemented by a service unit. It's the recommended way,
* through an integration service directly provided by the component.
{info}All attachment are processed by using XOP rules (XML-binary Optimized Packaging : [http://www.w3.org/TR/xop10/]).{info}

h1. Exposing a FTP connection as a service
The component is able to expose an external service in the JBI environment to send FTP commands on an FTP server (*Service-unit mode*).
h2. Usage
The operations of the service exposed are explained here after:
* an operation need to be call explicitly in the form : \{service-namespace}operation (example: \{http://petals.ow2.org/components/ftp/version-3}put)
* all operations support wild card character
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.

h2. Configuration
All needed information must be defined in the service-unit JBI descriptor. This JBI descriptor is configured through parameters divided in following groups:
* *JBI parameters* that defines the service provider identification,
* *CDK parameters* that are parameters driving the service provider implementation at CDK layer,
* *CDK interceptor parameters* that are parameters driving interceptors at CDK layer,
* *Dedicated parameters* that are parameters driving the service provider implementation at component layer.
h3. CDK parameters defining service provider implementation
The following parameters correspond to the CDK configuration of the service provider implementation.
{include:0 CDK SU Provide Configuration 5.8.0}
h3. CDK parameters driving interceptors
The following parameters drive interceptors at CDK layer.
{include:0 CDK SU Interceptor configuration 5.8.0}
h3. Dedicated configuration
The following parameters correspond to the component specific configuration of the service provider implementation, divided in two groups:
* connection parameters,
* other parameters.

h3. Service unit content
The service unit has to contain the following elements, packaged in the archive:
* the META-INF/jbi.xml descriptor file as described above,
* it is also highly recommended to provide a WSDL description for service provider embedded in the service-unit. The service provider contract must implement the interface "\{http://petals.ow2.org/components/ftp/version-3}Ftp" defined in the abstract WSDL 'FtpServiceInterface.wsdl' available as resource in the component archive.
{code}
service-unit.zip
+ META-INF
- jbi.xml (as defined above)
- service.wsdl (recommended)
{code}

h1. The integration service
The component exposes directly a generic FTP service without deploying a service unit (*Integration service mode*). This generic service can be deactivate removing the file '{{component.wsdl}}' from the component archive.
In integration service mode, parameters for the FTP connection are set in the XML message request in a connection node added to the operation payload as following. See [connection parameters|#connection-parameters] for more details:
{code:lang=xml}
<?xml version="1.0" encoding="UTF-8"?>
<ftp:... xmlns:ftp="http://petals.ow2.org/components/ftp/version-3">

h3. Service unit content
The service unit has to contain the following elements, packaged in the archive:
* the META-INF/jbi.xml descriptor file as described above,
* it is also highly recommended to provide a WSDL description for service provider embedded in the service-unit. The service provider contract must implement the interface "\{http://petals.ow2.org/components/ftp/version-3}Ftp" defined in the abstract WSDL 'FtpServiceInterface.wsdl' available as resource in the component archive.
{code}
service-unit.zip
+ META-INF
- jbi.xml (as defined above)
- service.wsdl (recommended)
{code}
h3. Example
An example of a Service Unit descriptor to provide an FTP service:
{code:lang=xml}
<?xml version="1.0" encoding="UTF-8"?>

h1. The integration service
The component exposes directly a generic FTP service without deploying a service unit (*Integration service mode*). This generic service can be deactivate removing the file '{{component.wsdl}}' from the component archive.
In integration service mode, parameters for the FTP connection are set in the XML message request in a connection node added to the operation payload as following. See [connection parameters|#connection-parameters] for more details:
{code:lang=xml}
<?xml version="1.0" encoding="UTF-8"?>
<ftp:... xmlns:ftp="http://petals.ow2.org/components/ftp/version-3">
<ftp:connection>
<ftp:server>?</ftp:server>
<ftp:port>?</ftp:port>
<ftp:user>?</ftp:user>
<ftp:password>?</ftp:password>
<!--Optional:-->
<ftp:folder>?</ftp:folder>
<ftp:transfer-type>?</ftp:transfer-type>
<ftp:connection-mode>?</ftp:connection-mode>
<ftp:delete-processed-files>?</ftp:delete-processed-files>
<ftp:encoding>?</ftp:encoding>
</ftp:connection>
</ftp:...>
{code}
Example of a PUT request :
{code:lang=xml}
<?xml version="1.0" encoding="UTF-8"?>
<ftp:put xmlns:ftp="http://petals.ow2.org/components/ftp/version-3">
<ftp:body>xml body</ftp:body>
<ftp:filename>file name on the FTP server</ftp:filename>

<ftp:delete-processed-files>false</ftp:delete-processed-files>
<ftp:encoding>UTF-8</ftp:encoding>
</ftp:connection>
</ftp:put>

h1. Configuring the component
The component can be configured through the parameters of its JBI descriptor file. These parameters are divided in following groups:
* *JBI parameters* that have not to be changed otherwise the component will not work,
* *CDK parameters* that are parameters driving the processing of the CDK layer,
* *Dedicated parameters* that are parameters specific to this component.
h2. CDK parameters
The component configuration includes the configuration of the CDK. The following parameters correspond to the CDK configuration.
{include:0 CDK Component Configuration Table 5.8.0}
h2. Interception configuration
{include:0 CDK Component Interceptor configuration 5.8.0}
h2. Dedicated configuration
No dedicated configuration parameter is available.
h1. Business monitoring
h2. MONIT traces
{include:0 CDK BC Business Monitoring Traces 5.8.0}
h2. Flow tracing activation
{include:0 CDK BC Provides Business Monitoring Flow Tracing Activation 5.8.0}
h1. Monitoring the component
h2. Using metrics
Several probes providing metrics are included in the component, and are available through the JMX MBean '{{org.ow2.petals:type=custom,name=monitoring_*<component-id>*}}', where {{*<component-id>*}} is the unique JBI identifier of the component.
h3. Common metrics
{include:0 CDK Component Monitoring Metrics 5.8.0}
h3. Dedicated metrics
No dedicated metric is available.
h2. Receiving alerts
Several alerts are notified by the component through notification of the JMX MBean '{{org.ow2.petals:type=custom,name=monitoring_*<component-id>*}}', where {{*<component-id>*}} is the unique JBI identifier of the component.
{tip}To integrate these alerts with Nagios, see [petalsesbsnapshot:Receiving Petals ESB defects in Nagios].{tip}
h3. Common alerts
{include:0 CDK Component Monitoring Alerts 5.6.0}
h3. Dedicated alerts
No dedicated alert is available.
