    MIDlet data security and file type after installation

    Hi,
    I am wondering if after a MIDlet is installed on a phone, without starting the MIDlet, is it possible to read out the containing data including the RMS record store or any kind of static variables or strings which were included in the class files in the jar?

    In what kind of file type is an installed MIDlet represented on a Nokia Symbian S60 phone anyway?

    Best regards,
    Hak

    Re: MIDlet data security and file type after installation

    If the MIDlet has never been started, there will be no RMS.

    An installed MIDlet suite is a JAD and a JAR.

    Usually, installed files are not accessible. However, this is device dependent, and may depend on whether the app is installed on a memory card or not.

    Of course, if someone has the URL to download the app, they can just download it to a PC. Then everything is accessible: data, code, the lot.
