    operator signed j2me / set permissions

    Hi,

    I have a J2ME application that is currently signed by Thawte. This app needs to have Read User Data, Edit User Data and Network Access set to Always Allowed. Whilst manually changing these settings is just about acceptable for advanced mobile users, it isn't great for the average customer.

    Now I am trailing with a mobile operator to sign my application using the mobile operator protected signing ID. I have a few questions to ask:

    1. Will the operator signing ID only work with devices that contain the operator root certificate?

    2. Can I sign the application with both the Thawte and mobile operator ID's. Has anyone experienced this previously? What was the user experience like ie are you asked on start-up which ID to use?

    3. Can the mobile operator send permission settings for J2ME, Read User Date, Edit User Data and Network Access to Always Allowed over the air, to avoid manual permission setup?

    4. Can the mobile operator send their operator root certificate over the air?

    5. Are there any methods to trigger app Permission settings on a device.

    Any feedback on any of the points would be greatly appreciated.

    Thanks,
    Alfe

    Re: operator signed j2me / set permissions

    My 2 cents

    1) yes. On other phones the installation will fail as the certificate cannot be found

    2) creates problems. you can sign the MIDlet to only one domain.

    3) Not exactly. the settings for that domain has been defined on the phone. Check for information about the operator specific setting for example here
    http://wiki.forum.nokia.com/index.ph...m_the_standard

    4) it has to be either on SIM or on phone.

    5) to change the default settings automatically. No.

    Note that not all operator have certificates.
    Note also that getting your MIDlet signed by the operator usually requires close partnering with the operator

    Hi,

    I have a J2ME application that is currently signed by Verisign. This app needs to have Read User Data, Edit User Data and Network Access set to Always Allowed.

    If I sign my application using Nokia signing certificate(Manufacturer Domain). I have a few questions to ask:

    1. Can any one give me the procedure to sign J2ME application using manufacturers domain(like Nokia).

    2. Can Nokia send permission settings for J2ME, Read User Date, Edit User Data and Network Access to Always Allowed over the air, to avoid manual permission setup?

    3. Can any one provide me the sample apllication which is signed by Nokia(Manufacturers Domain).

    Any feedback on any of the points would be greatly appreciated.

    Thanks,
    Reddy

    Re: operator signed j2me / set permissions

    First of all, most likely the manufacturer signing is not an option for you. It requires Nokia branding or that the MIDlet is developed by Nokia.

    2) No

    3) I do not know of any example jar and jad being available on net.

    Re: operator signed j2me / set permissions

    In theory, yes.
    In practice the answer is a little more complicated.

    Getting your MIDlet signed with an operator usually requires partnering with the operator.
    Also not all of the operators have code signing certificate on their handsets/SIMs
    Additionally some operators are using their own security settings from the operator domains, see here for more info
