No, usually Samsung phones doesn't allow to install java through PC.
You need to install it through Mobile Net (WAP)
And for samsung phone's java apps i always prefer http://www.wap.getjar.com
First select your Phone, then the type of app, and the most important thing is to check that specific app/game.. to be 100% tested under that phone . There will be a small tag with that app's discription, only try those with 100% Tested.

1. REMOVE THE BATTERY! Then place the phone in a bowl full of rice for a few hours (I suggest a day though). This should remove all moisture.

DO NOT TURN THE PHONE ON DURING THE DRYING TIME! This could cause PERMANENT damage!

2. Try here:
