playframework - do you need to know scala to play around with java play framework -

i have come across java play framework , have decided give shot after digging tutorial have started see scala elements ( index.scala.html ) has got scala related stuff, dont understand. m planning make basic chat app play in limited time frame, given case have learn scala ?

you can write application in java without knowing scala (except views). when things go wrong, though, want able read scala debug framework itself.
