Re: Cannot write content of temp file to remote ftp

[janvandeklok]

Thnx Claus for your response.  If nesting of the .from is not allowwed I
would expect an exception to be thrown. Now the route just ends normally,
leaving the programmer is a desperate state :-).

I fixed it now. Not by using the pollEnrich but by setting the temp file in
the exchange body when the fillTempFileWithaLotOfData processor is done
writing the data to the temp file like this :


public void process(Exchange exchange) throws Exception {
try 
{
   .. lots of other code 
   //create a temp file
File myFile = new File(tmpFileUri);
BufferedWriter buffer = new BufferedWriter(new FileWriter(myFile));

// ... write lots of data to buffer 
   
buffer.close();
   * exchange.getIn().setBody(myFile);*
}
finally 
{
}
}

This seems to be working OK.

Thnx again.

Jan van de Klok

Re: Cannot write content of temp file to remote ftp

You cannot have from in the nested route in the rest-dsl.

If you want to upload a file to a FTP server and write the file using
a temp name, then use the tempFileName or tempPrefix options. The
tempPrefix is the easiest to get started with
http://camel.apache.org/file2

And if you want to trigger the upload using rest GET call then do a

rest GET
 poll enrich file
  to ftp
