Are Java applications developed with the JDE portable to Symbian?

Vice versa?


If not (in either case), what can be done to ensure portability?

Re: Portability

Apps written for Symbian can be loaded onto a BlackBerry. The file-type must be .jar!


What you do is the following:

1) Load the application onto your memory card in the folder /Blackberry/apps

2) Then go to the Media application and click on the MenuButton

3) Then select 'Browse'

4) To to the selected path to your app

5) Select the app and click on download

6) Now the jar application gets installed on your Blackberry


Unfortunately I don't know how to port a Blackberry app to Symbian. There also might be some hardware-differences so not all apps would run on symbian devices.



If your question was answered, please accept it as a sollution and / or give Kudos ;-)
Use the Search Field first! Maybe the question you want to ask already exists!

Re: Portability

Many interesting applications will be built using native BlackBerry functions and libraries anyway.  All the Java stuff under net.rim.* is BlackBerry specific so can't by definition be run on a non-BlackBerry device.  It is of course possible to write an app that is java.microedition.* only, but depending upon your goal, it may miss opportunities to take advantage of the device.
