You can't use a root certificate that you have created yourself (that would defeat the entire purpose of the requirement for signing).

You must use a certificate that you have purchased from Verisign, Thawte or Java Verified. Not all phones support all certificates.

Just to reafirm what mikemoore says. NOT possible to install in a phone a certificate you made.

And add some link with information
http://wiki.forum.nokia.com/index.ph...curity_Domains

Check out the certificates section

Thank you for the reply.

But is there any way using which we can get it running with sample root certifcate...
I successfully installed root certificate in my device...

But looks like signing with child ceritifcate is not possible.

Can any one tell me the difference between code-signing certificate and another certificates?

Which one is required if i want my application runnning on blackberry and Nokia devices?

It might be best if you tell us exactly what you have done... In your earlier post you said you had an error message when installing the certificate. What is the message?

What phone are you using, exactly how are you trying to install the certificate? There are only a very small number of devices where it is possible to install a root certificate, and that is generally because they have a bug in the firmware.

Do you get any messages from WTK when you sign your application? What are they?

Once I have an exact understanding of what you are doing then I can probably help more.
