java.lang.Exception

start

public void start()
           throws java.lang.Exception

Specified by:

start in interface Endpoint

Overrides:

start in class PollingEndpoint

Throws:

java.lang.Exception

createLockManager

protected LockManager createLockManager()

getClientPool

public FTPClientPool getClientPool()

Returns:

the clientPool

setClientPool

public void setClientPool(FTPClientPool clientPool)

Set a custom FTPClientPool. If this property has not been set, the FTP client pool will be created based on the information provided in the URI.

Parameters:

clientPool - the clientPool implementation to use

getUri

public java.net.URI getUri()

Returns:

the uri

setUri

public void setUri(java.net.URI uri)

Configures the endpoint from a URI.

getFilter

public java.io.FileFilter getFilter()

setFilter

public void setFilter(java.io.FileFilter filter)

Sets the filter to select which files have to be processed. When not set, all files will be picked up by the poller.

isDeleteFile

public boolean isDeleteFile()

setDeleteFile

public void setDeleteFile(boolean deleteFile)

Delete the file after it has been succesfully processed? Defaults to true

Parameters:

deleteFile -

isRecursive

public boolean isRecursive()

setRecursive

public void setRecursive(boolean recursive)

Specifies whether subdirectories should be polled. Defaults to true

Parameters:

recursive - is a boolean specifying whether subdirectories should be polled. Default value is true. .

getMarshaler

public org.apache.servicemix.components.util.FileMarshaler getMarshaler()

setMarshaler

public void setMarshaler(org.apache.servicemix.components.util.FileMarshaler marshaler)

Set a custom FileMarshaler implementation to control how the file contents is being translated into a JBI message. The default implementation reads XML contents from the file.
