For the 6110, you will find it under Settings _> Phone Settings -> General -> Security -> Certificate management
Your added certifcate will be seen under Personal Certificates.
You just need to make sure that you send your certificate across to your phone via PC Suite (cvable or wireless) or just via file transfer. Make sure that the file has the correct extension.
hi keyurkarnik,
my certificate file extension is *.crt. and have added the certificate into the phone before install the midlet, 6680 and 6110. The certificate seems installed under "authority" not "personal". isn't this the problem? what should i do to make it installed under "personal"?
appreciate your help. many thanks.
theres no issue whether it is installed under personal or authority.
if the certificate has been installed on your phone, you just need to select the certificate and give it the required level of Trust in the Trust settings - thats all.
(In case you need to install the cert into the Personal certs, there should be an option during installationa s to where you want to install it, or post installation check whether you can move it - in the options you get after selecting the cert)
Once the necessary trust settings have been done for your application, your midlet should install and work!!
hi keyurkarnik,
l'm sure the same, otherwise it wont work on another phone nokia 6680, and has tried follow the steps using jarsigner and JadTool.jar as shown at http://www.spindriftpages.

That could be a problem. If it is not giving you an option for installation for self signed certificates,you will need a trusted certificate.
Do one thing - check if any of the other certificates like Verisign or Geo trust or others have the installation option.
If they do have, then you will not be able to use self signed certifs, otherwise we willl have to delve further
verisign dont have,MIDP2 GeoTrust got. mean i have to give up for phone 6110 caused i just updated the phone's firmware not so long, and according to the articles saying that the self-signed is not supported anymore on s60 3rd edition nokia phone. the below is Trust Domains found in the link you mentioned in my previous post, from here i can see that the Network Access dont have "Always Allowed" option even with signed certificate. does this meant proper signed MIDLET application also must request internet permission from user the first time?
Trust Domains
-----------------
Network Access: Not Allowed, Ask every time, Ask first time
Messaging: Not Allowed, Ask every time App
Auto-Start: Not Allowed, Ask every time, Ask first time
Connectivity: Not Allowed, Ask every time, Ask first time, Always allowed
Multimedia: Not Allowed, Ask every time, Ask first time
Read User Data: Not Allowed, Ask every time, Ask first time, Always allowed
Edit User Data: Not Allowed, Ask every time, Ask first time, Always allowed
if it is signed using a certificates which is authorised by a valid CA like GeoTrust or any other certified authority, you will have to set the permissions only for the first time. This is the way it usually happens.
You can try another tweak - at the cost of loss of functionality - use MIDP 1.0. It doesnt support certificates and stuff, so an unsigned midlet might just work fine.
By the wa, have you tried using unsigned midlets - usually they end up working fine without any certificates.
still ask for the first time even signed with valid CA? this is big problem for me, my midlet intends to launch automatically and run in the background using pushregistry and send GPS information to server via internet. if you are sure that permission would be still required the 1st time from user even signed with valid CA, then means i have to abandon this project. unsigned midlet? yes, i've tried before and works fined on both phone, but keep prompting for the permission to access internet,location and pushregistry. do you know any others way to stop the prompt?Not even once.

you should first try to install the self signed certificate on your mobile. This would be somethere in Security > Certificates..
Once the certificate is installed (you will have to transfer it using bluetooth or cable and then install it), you need to give rights to the certificate, then the midlet will work.
