scala - error: expected class or object definition

I have this (smart code):

import com.mongodb.casbah.Imports._
import com.mongodb.casbah.util.bson.conversions._
RegisterJodaTimeConversionHelpers() //error

object Main {
  def main(args: Array[String]) {
    val connection = MongoConnection()
  }
}

I get an error:

error: expected class or object definition
RegisterJodaTimeConversionHelpers()

I have to use this RegisterJodaTimeConversionHelpers() (2.2. Briefly: Automatic Type Conversions), but there's always this error message. Any ideas?

You have to write this line of code somewhere it can be executed. How about in your main method instead?

object Main {
  def main(args: Array[String]) {
    RegisterJodaTimeConversionHelpers()
    val connection = MongoConnection()
  }
}
