This is how I deal with a BufferedReader in Scala:

val br:BufferedReader = ???
val strs = Stream.continually(br.readLine()).takeWhile(_ != null)

You will have a string for each line from the reader. If you want it in one single string:

val str = Stream.continually(br.readLine()).takeWhile(_ != null).mkString("\n")
