Corrupted files with Camel Ftp component - apache-camel

Question

I'm using apache camel to make a ftp client for downloading some files to some local directory. The program reads a xml file to get the name of the file that will be fetched from the ftp.The program seems to work except that the files downloaded are corrupted. Right now I'm trying to download some image files but the ones I get are 14.9Kb and corrupted, no error message shown.
This is my code:
main
public void main() throws FileNotFoundException {
BasicConfigurator.configure();
RutaFtp routeBuilder = new RutaFtp();
CamelContext ctx = new DefaultCamelContext();
try {
ctx.addRoutes(routeBuilder);
ctx.start();
Thread.sleep(10000);
ctx.stop();
}
catch (Exception e) {
e.printStackTrace();
}
}
camel route:
from("file:./?fileName=Datos.xml&noop=true")
.split(xpath("//Datos/imagen/text()"))
.setProperty("rutaArchivo", this.body())
.log(LoggingLevel.INFO, "imagen: ${body}")
.process(ExtraerNombre).to("direct:ftp").end();
from("direct:ftp")
.pollEnrich("ftp://"+user+"#"+ftp+"/?password="+password+"&recursive=true&passiveMode=true&fileName=${body}&delete="+borrado+"")
.to("file:C:/outputFolder?flatten=true").end();
}
I've tried using the streamDownload parameter but tha prevents the files to be downloaded (I don't know why)
.pollEnrich("ftp://"+user+"#"+ftp+"/?password="+password+"&recursive=true&passiveMode=true&streamDownload=true&fileName=${body}&delete="+borrado+"")

Download image file in binary mode
By default, Camel FTP is downloading file by ASCII mode.
Add binary=true into your ftp route will turn from ASCII mode to binary mode
