Digital Signature in J2ME

[jayantb]

Hello Everyone,


I'm trying to build an testing application primarily focused on "Digital Signature". I am following the tutorial given in this link...

http://java.sun.com/developer/techni.../javame/satsa/

but while am running this example.. it is showing error:

[ERRR] [carddevice_simu] CARDDEVICE ERROR: javacall_carddevice_reset: can't connect to server

[ERRR] [carddevice_simu] CARDDEVICE ERROR: Reset failed

One more thing :

When i run this midlet on my mobile (Nokia - 2690). It is giving class not found error regarding two classes (CMSMessageSignatureService and CMSMessageSignatureServiceException). Nokia - 2690 have jsr-177 api. http://www.developer.nokia.com/Devic...ications/2690/Then why it is giving such an error ??

Thanks!!

Hi jayantb,

Nokia -2690 has the jsr-177 api but it dosen't support the the optional package SATSA-PKI that the example midlet you are trying to run is using.

Following packages are supported on Series 40

JSR 177 Security and Trust Services API for J2ME™ 1.0 (SATSA-APDU package)
JSR 177 Security and Trust Services API for J2ME™ 1.0 (SATSA-CRYPTO package)

What i want to do is :

1) Install digital signed testing certificate in my mobile device (using S60).

2) Create a SMS sending form in midlet.

3) Digitally signed the information using installed certificate before sending via SMS sending form.

How would do this??

Can i get any digital signature certificate trial version for testing purpose ?
