How to create multilanguage application?

[iworktech_kiran]

Hello friends,

I'm developing one application in J2ME + NetBeans for S40 2nd Edition.
I want my application in multilanguage (English + Hindi) when user selects English, all labels & control names should appear in English & same for Hindi.

Is this possible? How i can do this? If anyone have small demo of it please let me know.

Thanks

Hi iworktech_kiran,

You can create your own Internationalization (I18N) mechanism or use JSR 238 - Mobile Internationalization API for J2ME in case your target devices support it.

If creating your custom solution, it is just a matter of having a resource file for each lanaguage and a supporting class that allow you to retrieve the right label using pre-defined keys and the given locale.

JSR-238 is not available on any Nokia handsets as of now, and I guess there is no other phones either to support this API (although I can be mistaken in here...)

Hence your only valid option is to create the classes need for the multi-language support yourself.

One solution (if you do not have many strings you need) is to use the JAD attributes, but if you have a lot of strings the JAD file can get too big and the phone will not install your MIDlet anymore. The good point is that if you decide to sign you MIDlet you can change the JAD contents without needing to resign your MIDlet.

Another solution is to create a textfile for each of the languages which you then store inside the JAR file.
Etc.

The bottom line is that you need to do the work here. You cannot rely yet on methods allowing you to do an easy internationalization

Hi Hartti,

There are some few phones from Siemens Mobile (BenQ Mobile) that support JSR-238, both 65 and 75 generation phones (S75, SL75, etc).

They are still being marketed here in Brazil and Europe as far as I know, although the company is not in its best shape...

Br,

Good to know, thanks Juarez!
And soon (at some point in the future) there are more such phones as JSR-238 is part of MSA specification (JSR-248)...

Well i would suggest that if u r app is stand alone i mean not network based then use unicode to display ur text and according to user selection show him that unicode.. i think this should work fine.

hi
All you have to do is to write the unicode values of the characters and save it into a resource file. At the time of displaying you can pass the unicode values of the characters. If the phone supports the font then it will display the character else it will display the unicode value itself.

If you need some help on using light weight font system independent of the font model then please contact me here.
