Your `listvalues` seems to be a java.util.List, not a scala.collection.immutable.List, right? In that case, toArray() will return a Array[Object], not an Array[String], which leads to the error you see. Have a look at http://www.scala-lang.org/api/current/index.html#scala.collection.JavaConversions$ and convert your Java list to a Scala list. Tobias
