    white screen after launching push registery midlet

    Hi all,
    We developed two applications,we are successful in launching application2 from application1 using push registery.
    when we press some menu option of application1,we pause application1 and start our application2 and if we press exit command of application2,control comes back to application1.

    The above scenario works only once,when control comes back to application1,now if i press the same menu option of
    application1 which launch application2,we get a blank white screen ....

    Can any body help me to know the cause of this white screen???

    Note:
    1) We use midlet.pauseNotify() to pause the application1 and start the application2.
    2) we are using destroyapp(true) notifyDestroyed() while returning back from application2 to application1.

    Thanks,
    Mutturaj

    Hi,
    With which device you are working...?

    Is there any alert/exception shown by the device itself...if yes then what/which??

    is this happening on the emulator ..too.Please try to debug the same on emulator.
    On the device ..I would say a few points..

    @ Check that whether the Out of memory is not coming..
    @ There is no null pointer exception..
    @ you have set the current displayable to the first application...
    @ have you paint the canvas...
    Thanks with Regards,

    Re: white screen after launching push registery midlet

    Hi,

    My problem solved,it was a thread issue.

    We tried launching two differents midlets from same jar file.

    Is it possible to invoke midlet from other jar???
    I mean to say,first we run application1 then we download application2.jar and launch application2 midlet.
    Is it possible using j2me???

    thanks,
    mutturaj
