Question

Sign a J2ME application and add a certificate to the emulator used

Asked by: phpamble

I need to sign a J2ME application so that I can use the File Connection functions in JSR-75. The program that I am testing works using the default emulators in the NetBeans IDE, that all have security certificates. When I run the program using an emulator from Nokia (has no security certificates). I get the following errors:

Uncaught exception java/lang/ Security Exception: Access Denied

I need to know the steps on how to add the security certificate and sign the application.

This will give you some more details.

By the way, if you do not add any certificates, your stuff can still work fine without any authorizations. All you will get is a warning saying that your midlet is unsigned or unsecure - do you still want to install it. - Once you continue, it works just fine.

The issue comes only when you have added  your own certificate which cannot be verified by any of the certificates in the device. (Any certificate you have has to be signed by some Certification Authority, or there should be a certificate chain linking to a root certificate)

So the best way is to make sure that there are no certificates in your midlet - keep it plain simple unsecure and unsigned - it will work.

There is one thing you need to know - depending on the operator, the device may or may not allow an umtrusted (unsigned) midlet to access the PIM database. So you could try on a couple of devices.
Read this article - its specifically about the PIM access
