Re: Can JTAPI do this?

Hi Ian,

This feature is implementation dependent. You should get developers
manual for your mobile phone and figure out what APIs are protected from
unauthorized use. Protection can cover only part of some API. For
example for JTAPI it could deny you to make calls or receive calls or
something else. To grand permission to you MIDlet to use such protected
APIs you should have certificate - private key for RSA encryption
algorithm to sign your MIDlet. This is a secret key and it is not
available from free sources. When the MIDlet trying to access protected
API, Java VM (KVM in our case) checks digital sign for your MIDlet and
if it is OK, you can call protected function. Otherwise you'll get
SecurityException. 

PS: You can read about signing procedure in Sun WTK 2.2 docs. The tool
is also available in WTK distribution.

Regards,
Michael

Hi Michael:

You say I need to sign my MIDlet with special certificate to use this
JTAPI
functionality on mobile phone. I am not so smart for understanding the
concept about this.
Can you give me some clues or tips or sample about that?

Thanks in advance
Ian
