    Re: Problems in Installing jar and jad file on to Nokia 6300

    Hi grahamhughes ,

    First of all thanks for help me.

    Today I changed the version of manifest file by 1.0.0 but doesn't works.I explain you the steps that I do:

    1.I transferred the .jar file to my nokia 6300 via bluetooth.
    2.Then, I open the .jar file and my phone ask me "Do you want to install?"
    3.I select Yes.
    4.I have to choose where I want to intall it: Telephone memory or memory stick.
    5.I try in both places (Telephone memory and memory stick)
    6.Begin to install but don't finish because appear an alert that said aplication error.

    I try with others nokias and always appear the same missage.

    Thank you very much!!!!!!

    When it says "application error", does one of the softkeys have a "details" option? If so, what are the details?

    Does the same JAR install and run on a device from a different manufacturer?

    Hi ,

    When it says "application error", does one of the softkeys have a "details" option? If so, what are the details?

    What do you mean when u speak about softkeys? When I try to install the application the mobile doesn't ask me to enter any key,only appears an alert that says "autenthication mistake"

    Does the same JAR install and run on a device from a different manufacturer?
    The jar was made by me and i used NetBeans and nokia6300 emulator.On my computer it worked but when then i tried to install on my device and appears an alert that says "autenthication mistake"

    If u want i can send u my jar file

    Thanks

    "Softkeys": the keys below the screen, which are used to active Commands.

    Is it "application error" or "authentication mistake"?

    Yes, I think it would help if you add your JAR file as an attachment to your reply.

    Cheers,
    Graham.

    OK... you have classes in your JAR that are in "java." packages. You are not permitted to have classes in these packages, since it would enable you to bypass some of the sandbox security.

    I'm afraid the problem is a little more than a rename.

    You have classes in your JAR like "java.math.BigInteger", and you can't have this class in your JAR (because the package name starts with "java."). Simply renaming the folder will just make the class impossible to find.

    Try obfuscating your application, and make sure that all package names are removed by the obfuscator.

    (Incidentally, why "java." classes are not allowed (and "javax." and others): internally, the API implementation classes rely on being able to communicate with each other using package-private methods (methods that are visible only to other classes in the same package. If you could put your own classes in the system packages, then your classes could access these package-private interfaces, and access functionality that you shouldn't be able to. For example: a bug in some early Series 60 devices allows you to have classes in the com.symbian packages. Using this "loophole", it is possible to write an application that can send SMS messages without any security prompts to the user. This should not be possible, to protect the user's privacy, data and phone bill!)

    Graham.
