Make my J2me Application trusted

[amithgc]

Hi Developers..

How should i sign my j2me application? so that it becomes trusted. because if my J2me application is untrusted then

System.getProperty("CellID"); or any other property in case will return NULL.

Please help

with money you can send your midlet to verify it. look and see detail at http://developer.motorola.com

with out money. Like us. you midlet always unsigned. but we hack it. by changing midlet domain after installation complete.

in file .system/java/DownloadApp/MIDletXXXX/registry.txt

Is-Trusted: 0 to Is-Trusted: 1
Domain: Untrusted to Domain: Manufacturer

or

Domain: Untrusted to Domain: Trusted Third Party

after this we got a permission. but we need to manage it by
1. Manage midlet permissions by tap and hold on midlet icon
2. select Manage.
3. select Permissions.
4. set permissions that you want to use to Never Ask for Manufacturer domain or Ask once per application for Trusted Third Party.

Manufacturer domain make midlet unupdatable. only uninstall it before you can install new version. but does not ask any question. Trusted third Party will ask for each permission once per application at least. but can unistall.

but in a developing stage. you can install midlet. hack permission to manufacturer for easy testing. and then direct copy your jar and jad into .system/java/DownloadApp/MIDletXXXX/Files. this is helpful for me when create a restrict permission midlet. and don't forgot to add

MIDlet-Permissions: javax.microedition.io.Connector.file.read, javax.microedition.io.Connector.file.write

in your jad file. I use Netbeans It can done in project property dialog.

Just incase anybody is wondering, it cost $400 USD to have a midlet signed

Hi all,
I am Mudit Gupta, using j2me for my project development. I hacked the mobile and changed the permissions in registry.txt file but i am facing problem in running the application. The application gives me NULL value on my Motorola A1200 phone.

i changed the permissions of my application through registry.txt file --
I set Is-Trusted: 1
and Domain: Trusted Third Party.
but not working..........

Any suggestions???

i am using FileConnection API's JSR75
File Read and
File Write

but error while running the application, giving NULL value

Even after changing the Domain to Manufacturer and Setting the app as trusted, your JAD should be there. Also after making the hack...sometimes you need to save the permission settings twice / thrice for it to come into effect. Hope it helps.
