    How can I sign up a Midlet?

    Hi Everyone,
    I have developed an application using J2ME Polish in NetBeans IDE targeting Series 60 3rd Edition devices. I got the Thawte Certificate "PKCS #7 Certificate Chain". But when I signed up the application with Sun Java's Keytool using this certificate, the signup is successed and it runs in the simulator fine. But when I installed the application in Nokia N82 device, the installation failed saying Invalid Jar File.

    I think there will someone who can help me?

    Thanks in advance.

    Hi,

    Can you please check whether the N82 has thawte root certificate or not because this is one of the main reason for above error.

    Regards

    Hi bijen.singh,

    in addition to Amit's reply, have you checked that date and time are correct on your N82?

    Some other useful infos could be:
    * does the unsigned MIDlet successfully install?
    * how are you deploying your MIDlet (e.g.: OTA)?
