You're on the right track using JavaConversions, but the method you need for this particular conversion is seqAsJavaList:

java.util.List convert(scala.collection.Seq seq) {

}

Update: JavaConversions is deprecated, but the same function can be found in JavaConverters.

java.util.List convert(scala.collection.Seq seq) {
    return scala.collection.JavaConverters.seqAsJavaList(seq);
}
