2. Introductions
⢠Allows your Mule application to exchange files
with a file system
⢠You can implement the File connector as an
inbound endpoint (such as, a message
source), or as an outbound endpoint
⢠This endpoint implements a one-way
exchange pattern only
3. Configuration
⢠File endpoint configuration consists of two
stages:
â Place the File endpoint within the Mule flow you
are developing
â Configure the File endpoint by providing values for
the fields on the various tabs on the properties
editor
7. Outbound endpoint
Property Description
Display Name Defaults to the generic endpoint name.
Change the display name, which must be
alpha-numeric, to reflect the endpointâs
specific role, such as Order Entry Endpoint
Path The target directory on the connected file
system. If File is implemented as an inbound
endpoint, this would be the location within the
connected file system of the file being
transferred into the flow. For an outbound File
endpoint, this would be the directory on the
connected file system to which the file
currently in the flow is written.
8. Outbound endpoint
Move to Pattern (Applies to inbound File endpoints only) .
The pattern to be used when moving a file
according to the Move to Directory
property. It can use the patterns specified
by the filename parser configured (often
through a Connector template) for this
particular File endpoint.
Move to Directory (Applies to inbound File endpoints
only.) Typically, the file being received is
simply read by the inbound endpoint and
dispatched to the next building block in the
flow. To save a copy on the Mule host
machine, specify a path in this field.
9. Outbound endpoint
Connector Configuration Use the dropdown list to select a
previously created connector
configuration for this endpoint. If
you have not created a connector
configuration for this type of
endpoint, you can do so from this
window by clicking Add .
Click Edit to modify a previously
created global element.
Polling Frequency (Applies to inbound File endpoints
only.) Specify how often the
endpoint should check for
incoming messages. The default
value is 1000 ms.
10. Outbound endpoint
File Age (Applies to inbound File endpoints
only.) Sets a minimum period a file
must wait before it is processed.
This helps ensure that long files
are received in their entirety
before processing starts.
However, Mule and the connected
file system must be on
synchronized time for this feature
to work properly.
File Name Regex Filter (Applies to inbound File endpoints
only.) Configure a filter to restrict
the files being processed.
11. Outbound endpoint
File Name / Pattern (Applies to outbound File
endpoint only). Specify a
filename or pattern for naming
files that are sent from the File
endpoint to the connected file
system. If not set, the File
endpoint uses the same file-
naming pattern used for
incoming files
13. Advanced Tab
Property Description
Address Enter the address for this
endpoint, such
as http://localhost:8081/file.
Response Timeout Specify how long (in ms) the
endpoint waits for a response
from the connected file system.
Encoding Choose from a drop-down list the
character set used for message
data. (such as UTF-8).
14. Advanced Tab
Disable Transport Transformer Check this box if you do not want to
use the endpointâs default response
transport.
MIME Type Select from the dropdown list one
of the formats this endpoint
supports.
Connector Endpoint Use the dropdown list to select a
previously configured global
endpoint reference. If you have not
created a global element for this
type of endpoint, you can do so
from this window by clicking Add.
Click Edit to modify a previously
created global element.
15. Advanced Tab
Comparator (Applies to inbound File
endpoints only) . Specify the
comparator used to sort
incoming files, as
in org.mule.transport.file.compar
ator. If you write your own
comparator, it must implement
the java.util.Comparator interfac
e.
19. Transformers Tab
Property Description
Transformers References:
Request
Enter a list of synchronous
transformers that are applied to
the request before it is sent to
the transport.
Global Transformers
AND
Transformers to be applied
Reference the global
transformers you desire. Enter a
list of synchronous transformers
that are applied to the response
before it is returned from the
transport and order them for
your needs.
