Hello everyone here.
I am new in J2ME programming and I manage to create an alternative mp3 player for s40 v2 phones (which includes my own n6230i)

A such player needs to browse internal phone folders seeking for supported audio files;
I got the algorithm that lists all files in a folder, however, when running a midlet that uses FileConnection Api (JSR-75), the application needs user confirmation every time the folder in search is changed, so the phone prompts user every time the application attemps to acces a local folder

It is quite disturbing when you use an MMC with 1GB and a lot of folders included within...

I know it is possible to let a Midlet accessing the phone for read/write without user prompt, but it needs a "certificate", which roughly seems to be an encryption key or something like that...

My question is: How to inlcude a such certificate in a midlet ?

I am using NetBeans 4.1 with Mobilty Pack to compile my applications and then I transfer to my phone through a DKU-2 Cable using PC suite

Any help is welcome

Best regards

It is not just about getting a certificate, but it is about getting a certificate and having a trusted party sign the application. In the case of Java it means going through the Java Verified process: http://www.javaverified.com

In addition to the Java Verified path you can probably get (buy) a certificate from a CA (like Verisign or Thawte) and sign your midlet with that. The corresponding root certificate has to be on your phone (you cannot install them yourself)

You can check which certificates are in your phone through this path
Menu > Web > Settings > Security settings > Authority certificates
(I hope I remembered correctly that this part is used on 6230i, if the above path does not work then try Menu > Settings > Security -> Authority certificates)

Hello witson.

How did you manage to play a large mp3 for example ( > 3MB) into your audio player ? I'm also building a customized music player for S40 3rd ed, but i cannot play an mp3 larger than 1 MB (it runs out of memory when you prefetch the player).

Please refer to my post http://discussion.forum.nokia.com/fo...ad.php?t=95500

Thanks!
