outputting json

Hi,

I'm looking for a way to output (build) json.

For example, I see there is a way to build xml
http://www.scala-lang.org/intro/xml.html

object XMLTest2 extends Application {
  import scala.xml._
  val df = java.text.DateFormat.getDateInstance()

  val dateString = df.format(new java.util.Date())
  def theDate(name: String) = 
  <dateMsg addressedTo={ name }>
    Hello, { name }! Today is { dateString }

  </dateMsg>;
  println(theDate("John Doe").toString())
}

Is there a way to output JSON rather than xml?


Something similar to what I"m looking for is found in groovy

Thanks,
