    Phone restarting after installing jar

    Hi everyone,

    I am installing jar of my application in the Nokia 6681.

    The phone is behaving in an unusual way, while installing the jar.

    Sometimes the jar file takes a hell lot of time to install. Though the jar is of only 44kB and there is plenty of space in the memory card, where I am installing the application.

    Another issue is, when, somehow it gets installed ina short span of time, the phone restarts itself by default.

    Though the application gets installed.

    All the applications that I developed in J2ME, never made the phone to behave in this fashion.

    Please guide me through this situation.

    Regards,
    Ashish

    Hi,

    I use Nokia 6681 and never faced problems related to jar installation and also I've never heard about such issues. BTW, I'd like to know your firmware version, mine is below:

    V 3.10.6
    11-04-05
    RM-57

    Just type *#0000# to see yours.

    Hi jurazJunior,

    The firmware version of my 6681 is: -

    V 4.00.15
    28-05-05
    RM-57
    Nokia 6681


    I have developed many applications in J2ME and have installed their jar file in to this phone only, but none of my previous application has shown such a response.

    I figured out one reason for this behaviour. There were some SOPs in the application, when I removed them, it didn't restarted the phone, and the application behaved normally.

    Does SOP has to do anything with the restarting.

    I would like to know what actually the installation process does, apart from retreiving the class files, just to get the idea of the reason behind it.

    Regards,
    Ashish

    Hey ashish,
    good observation man.. i had similar experience with my 3230. That may be because of SOP's i had in my appln. I need to observe this. Does this a common behaviour with S60 ??

    Hello Daniel,

    By SOPs I mean System.out.println() statements...

    Does this problem has to do anything with the memory constraints.

    Please help, I need to get to the root of this problem?

    Regards,
    Ashish

    Hello there,

    I do not know the answer. But I have one more question to think about.

    System.out.println() calls are problem because they cause a lot of I/O calls. This can degrade the performance of applications, in Java. What about JME?

    Does It trouble the KVM, perhaps CLDC HI? Nokia 6681 (Symbian OS v8.0a) uses CLDC HI. Right?

    BR,

    Re: Phone restarting after installing jar

    Can you please tell me how you solved this problem ?
    My application used to work before on the same firmware version.
    I changed the cldc version cldc1.0 to try it on 6600 .It works on 6600 without any restart. I made the required changes , changed cldc version back to 1.1 and then the phone restarts(N72).

    I have many appends to the screen and form but why would this restart the phone during installation. After installation the application works fine..

    What all causes a restart during installation ?
