It seems only the casbah we can use in scala, but I hope there is a orm-like library for scala, like morphia for java, or something else.
Is there any? I don't want to use morphia in scala because I have to convert java collections to scala
UPDATE
I've tried some of them, but still not find a proper one. Some are hard for scala newbies to get started.
FINALLY
Finally, I chose mongo-scala-driver, its awesome. Thanks to everybody.
There are two solid options:
Salat, which is designed to integrate with Casbah using case classes and scalasig - https://github.com/novus/salat/
Lift (liftweb.net) also has an activerecord ttype library for Mongo which Foursquare has built a DSL, Rogue, for. http://engineering.foursquare.com/2011/01/21/rogue-a-type-safe-scala-dsl-for-querying-mongodb/
Spring Data is releasing Morphia-like mapping capabilities in the M2 of the MongoDB support. We've talked about doing some native Scala support for this but we haven't had anyone ask for it directly, so its hard to gauge interest. It should be usable as-is from Scala--though there are things I'd like to see us make more Scala-ish.

If this is the only reason, I suggest you to use scala.collection.JavaConversions It contains implicit conversions from Java to Scalca collections and vice verse.
