Camel download files

I have maybe a stupid question but how I can to download files from ftp server. I use the route

.from("ftp:/test@localhost:21/?password=test") .to("file:/d:\\test")

I have the error : can not store null body. Why ? I read several examples Where is my error? Thanks

EDIT

I use the route :

.from("direct:xx") .from("ftp://test@localhost:21/?password=test") .to("file://d:\inbox");

And I have the error :

org.apache.camel.component.file.GenericFileOperationFailedException: Cannot write null body to file: d:\inbox\xxxxxxx at org.apache.camel.component.file.FileOperations.storeFile(FileOperations.java:237) at org.apache.camel.component.file.GenericFileProducer.writeFile(GenericFileProducer.java:277) at org.apache.camel.component.file.GenericFileProducer.processExchange(GenericFileProducer.java:165) at org.apache.camel.component.file.GenericFileProducer.process(GenericFileProducer.java:79)

Add parameter 'allowNullBody=true' to your TO file endpoint

to("file://d:\test?allowNullBody=true")

If you go deep into source code as state in org.apache.camel.component.file.FileOperations.storeFile(FileOperations.java:237), you will see the related GenericFileOperationFailedException happens when

  1. In Body of exchange is null
  2. allowNullBody is set to false

By default, allowNullBody in File producer is 'false' as state in Camel File Component. You need to change it to 'true' to allow storage of empty files.

This should work.

.from("ftp://test@localhost:21/?password=test").to("file://d:\\test")

I am pretty sure about the from part. But the to part you might have to change a little bit(wrt '/') because I have not worked on windows
