The following guide will explain how you can install a Java application on a low- or mid-budget mobile phone that doesn't feature an operating system. Before reading the tutorial check to see that your handset is Java compatible and that you have a Bluetooth connection or a memory slot card.
There are two widely known methods of installing Java applications, and you can use the one that suits you best. The first one implies that your phone is Bluetooth compatible with OBEX standard and that you have a Bluetooth dongle that you can insert into your PC (MAC owners don't need that).
If your handset doesn't have an embedded File manager, you will need to install Fexplorer
to be able to transfer the data to your mobile. Java applications are known to have the file extensions .JAD and .JAR, and you can install either of them, but not both. However, bear in mind that there are certain models that only support .JAR file types.
After downloading the desired application onto your PC you can transfer it to your phone, as you can see in the screenshots, using Bluetooth File Transfer Wizard. You can also use any other third-party software compatible with whatever OS your computer is running. The idea is to make a Bluetooth connection between the phone and the PC. The phone will receive the file under the form of a message that you can choose to save (if it's a music or an image file) or install (if it's Java compatible).
Open the newly arrived message and choose to install the application (game) that you just sent through the Bluetooth connection. I recommend installing it on the memory card (if you have one) in case you have a low-memory phone. This will probably take its toll on the speed of the device when you open an application installed on the memory card, but you'll have more internal memory left. Of course, you can place it in the phone's memory if you want fast booting times for your apps.
For the second method you will need a card reader, a phone that features a memory slot card and a memory card. Put the memory card into a card reader and place the Java application you want to install on the phone in the root directory. Do not put the file into any directory, unless you are certain that your phone can read it afterwards. Pull out the memory card and insert it into your phone.
Start the File manager that you previously installed (Fexplorer
) and go to the location of the file on your memory card. Click it and the installation process will start. After you're done you can delete the .JAR file from your memory card in case you need space.Note

Ok, first of all can you do this on ANY midrange phone, like say, the Samsung Messager Touch (R630)? Because I have tried everything I can think of, and there is no option to install it. When I tried Bluetooth, if its a file type other than a picture or music file, I can't even download it. I tried to change the extension to .jpg, which I read will allow you to download it to the phone, but it is displayed as a "picture" file, but its not recognized, it only displays a black box with a white question mark on it. Am I missing something? The file I want to install is Google Maps java version 4.0.0. Sending it via email is worthless because I cannot click links or attachments in this phone. Thank you in advance.
|Comment #4.1 by: Cosmin Vasile on 22 Jun 2010, 14:02 GMT|
Try to use a card reader and put the Java compatible file on a memory card. After that simply put in the card into the phone and install the application (.jar or .jad file).
|Comment #4.2 by: Stopokingme on 20 Aug 2010, 16:51 GMT|
Anyone ever found a way to get them working on the Samsung Messager Touch r630? I get the same thing - no directory to put theim in via USB link - when trying to download, from a WAP site it will always give "unable to load page (HTTP 406) #0 when tryingto download .jar.

please help me..
|Comment #8.1 by: Prince Tahir on 27 Apr 2011, 12:06 GMT|
The three limitations are:
1) You can't install the application with the JAR file only, you need the JAD file.
The JAR (Java Archive) file is a zip file which contains the program files for the app,
while the JAD file is like an index file for the JAR and is called "Java Application Descriptor" file.
2) You can't install any single JAR file larger than 500 KB, which may prevent you from
installing lots of useful apps and great games larger than 500 kb.
3) The total space available for Java apps and games is only 4 MB, and we still haven't figured out a way to change it yet.
Generating a JAD file:
1) To overcome the first limitation, we'll be using an excellent software called JADMaker, you can get it here:
2) To use the software, simply drag the JAR file and drop it in the program's window, and it will automatically
generate the JAD file with the same name and the same directory of the JAR file.
3) Now you have both the JAR and JAD files, simply send them over to your phone (via USB or bluetooth or whatever),
but place both files in the same directory on your phone.
4) To install the java app on your phone, open the JAD file from "My Files", the phone will ask you for
confirmation then installs the app, and you can open your application from "Applications/Games and More".
Changing the Maximum Limit:
If your JAR file is larger than 500 KB, the phone will refuse to install it, so you have to increase this limit.
1) At the standby mode, enter the following code:
which is the code equivalent to
2) Goto "6) OTA test".
3) Now change the "Maximum JAR size (KB)" to any larger limit, 2048 KB is a reasonable limit.
4) Save and exit the java test menu and try re-installing the file.

@ Prince Tahir
Nice work! Its good to help others!
Also users need to know that if you want to use Java applications and Games on Samsung phones that support it they have to be installed. Which means that the maximum number of Java applications and games that can be stored on a Samsung phone is equal to the amount of free internal memory that the phone has.
Other companies often do not have this restriction such as Nokia which can even run Java applications and games from the memory card without installing.
