I have also tried the \n and I have now implemented a converter but it seems,
that the
text.replaceAll("\n","<br/>");
Doesn't seem to work, because doing the following just prints the same result
in both System outs.
System.out.println(text);
text = text.replaceAll("\n", "<br/>");
text = text.replaceAll("\r", "<br/>");
System.out.println(text);
Do I perhaps have to escape the \ before the \n? It's a bit curious..
Regards
Andy

Sorry, \r was for my special case.
\n should be right for your case!
But definitely go with Mike's suggestion and do a converter...
