In a JasperReport(iReport) I need to replace the character"^" in a string with \r\n. It is a field expression.

First of all, are you sure it's really the character ^? Some editors show unknown characters using a ^; for instance, VI turns \r into ^M.

If you are certain it is ^ you need to replace, you need to look a bit closed at regular expressions. replaceAll takes a regular expression, and ^ is a special character in regular expressions representing the start. Either use replace (with String parameters, added in Java 5 or 6) or escape ^ to "\\^". That's two backslashes - one to escape for use in Java strings.
