Getting legit java apps for my samsung phone (BADA OS)

Is there a legit repository of java apps for a samsung wave y phone (bada OS 2.0)
I am trying to search for a audiobook player. but can't find any. There is nothing on samsungapps.com, so am looking if I can find some java app to do the same.

I tried a few shady sites to get hold of some jars but even though they installed in the phone , they don't work right at all.


Also the phone is my fathers so can't do anything like rooting.

Thanks
