In many cases this trick was helped.
download the .jar file of application. then convert the same file into .jad format. then copy the both file (i.e. .jar and .jad) to the memory card and through cell install the .jad file.
Please let me now was this works on ur phone. This trick works on my cell (i.e. Samsung S3500)
Thnks

through mobile gprs visit www.zedge.net,ownskin.com directly you can get it ,or else download in your pc and copy it in memory card and then install it

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.

Download Games onto the memory card and do as BELOW:

1. Transfer the .jar & .jad files to the Other Files folder. You can transfer the files using Samsung PC Studio Phone Explorer, or you can transfer the files to the memory card and move them to the Other Files folder from the phone's menu.
2. Exit all menus and Dial: *#9998*4678255# - This will activate the Java Install menu.
3. On your phone, Go to the Other Files folder >> Select the .jad file >> Press Options (Left touch key) >> Message displays: Do you want to install >> Press Yes to install.

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!
