Java installation problem

Download the jar file through your pc. Create a jad file. (Download jad maker software here.) Open the jad file using notepad and change the MIDlet-Jar-Size to some value in bytes less than 300kB (e.g. 12345). Copy the two files (.jar and .jad files) to your phone and open the .jad file. Install when prompted.

Here's how to install games on Samsung Corby B5310 in 8 Easy Steps:

1. Download the .jar java game file/s on your computer

2. Download JadMaker software installer via this link.

3. Install JadMaker on your computer.

4. Read text file in JadMaker folder to learn how to convert jar file to jad. (Drag and drop a JAR file onto the window. JAD generated. That's it!)

5. Convert .jar java game files on your computer to jad

6. Sync your Corby phone to your computer or remove memory card of your phone and plug it to your computer.

7. Transfer BOTH .jar and jad java game files to your phone's memory card.

8. Navigate phone memory and click on the jad game file you want to install. Install and enjoy game.

Just place a jar files(games or apps) on a memory card. Then just click on the apps or games it will install. Samsung champ will only install below 500 kb/apps or game, if you want to install higher than that just used this code by dialing *#52828378# you will go to Java Test Menu, then go to OTA test, change 500 to 4000 then save. You can now install as much higher than 500 kb but less than 4 mb.

Just use your samsung PC suite and you can install .jar files.
otherwise copy in memory card and use them. remember only .jar files.

if you dont have a pc suite for your phone, you can use a card reader and upload the .jar files in the memory card. insert the card back to your phone and open the .jar file. the system will prompt you to install the application or not.

I had the same problem on my s3550. And now i found out from myself what the problem is. I Assume you have memory card and u are trying to install the games from the memory card. That is the problem. Just copy the game you want to install into the telephone memory and install it from there. It will solve your problem. I am so happy to help you. i hope you see this.

for installing java games n apps,first in the main screen,dial a no...."*#9998*4678255#.
then put the java app's jar n jad file in "other files" folder of the memory card n pres the center(play/pause) button to open it.

if u instal proper jar file it will open , try to install java jar file , like 170/120 pix , do not install any 3d games ,

we can transfer the java games by using the data cable. following are the steps 1. connect the mobile with the PC by using the data cable 2. transfer both jad and jar files to the "MTP" folder in the memory card of the device. 3. disconnect the data cable 4. go to "my files" menu 5. go to  the "memory card"  5. move both the JAD and JAR files to the "phone"  6. get back from memory card to my files
device will ask for the installation of the game. if not, follow the steps below.
7. select the "other files" folder
8. select the JAD file.
the installation prompt will be displayed

1. Transfer the .jad and .jar files to the phones memory to the 'Other Files' folder.
You can transfer the files from Samsung PC Studio's 'Phone Explorer', or just transfer it straight to the memory card and move it to 'Other Files' from the phone's menu.
If you don't have a .jad file, you can download 'Jad Maker' (google) and make a new one.

2. Exit all menus and type in this code: *#9998*4678255#.
You should now get a 'Activated' message. Java install is enabled.

3. Go to the 'Other Files' folder and select the .jad file (should be 1kb).
Press 'Options' (left touch key) and you should get a 'Do you want to install' question.
Press 'Yes' to install.

4. To deactivate Java install, simply type the same code again.
You should now get a 'Deactivated' message.

It took me awhile to work out so i thought i would post this incase anyone is struggling in the future
