Help with newline while writing to the file.

[dmhatre <da...@gmail.com>]

Hi Folks,
   Need help adding newline while writing to the file.
I am writing very large file using Apache Camel's File Component.
I am using StringBuffer to store very large string and then passing (passing
string ex.getIn().setBody(stringbuffer.toString()); )  it to the 
file endpoint (<to uri="file:c://cameldata/loanet/outbound"/>)
This works fine and the file is created. But when I append "\n" newline
character
the newline character is displayed as it is in notepad and other editors.
Is it possible to print the data in next line instead?

for(int i=0;i<=10;i++){
    stringbuffer.append("some records \n");
}

What about using Stream component [1] for that purpose? Instead of
caching lines in StringBuffer you can send them to the file as they
arrive.

from("seda:linesQueue").to("stream:file?fileName=outputFile");

This is more message-oriented-middleware way of handling large output files :) .

It works for me on OSX. You may have to use '\r\n' if your OS in Windows...
And by the way, you know you can use
System.getProperty("line.separator");...

Best,
Christian
