Re: How to append text to the beginning of the file using Camel

[souciance]

You could perhaps PollEnrich to fetch the data from the file then then
simply concatenate the new portion to the file data and then write to the
same file again. But its easier to write some bean method to do this.

Hi

Yeah write your own java class / method that appends to the start of the file.

There is no such functionality out of the box, as fileExists=Append
appends at the end
