hi, dear all:

I have implemented a j2me program. And I have been asked to update by OTA.

I build a simple IIS server and add some mime types for supporting jad and jar download. But I can't make the version check working.

I read some books, they said it will auto check the midlet version on the server and user device, and if the version is older, it will prompt user and doesn't start the download.

My situation is it will always download, no matter the version is newer or older.

Please tell me why or how to enable the version check.
Thank you all in advance.

Always do precise the phone you use and its firmware version. With other phones?
Whether the version is newer or older, I always get a prompt.
How did you format the MIDlet-Version? Maximum 2 digits per number: 1.99.23 okay, 1.0.100 is wrong.
If you transfer directly from PC to phone over bluetooth/usb, same problem?

dear lapinos:

Thank you for your rapidly reply. I use three models for testing this issue, they are all S40 6th os build-in, and of course, different build date.

I think the format is well, I even use the eclpiseme option of auto-increase version number.

And I also try to use the nokia PC suite to install my program(via Application Installer), and it also don't prompt me the version info, only tell me the appllication is already on the device, do you want to overwrite it.

But there is one thing could be the reason, my program just under development, and there is no signing at this moment.

I still feel bad about this version check mechnism. Do I need to do it by myself?

Thank you again, any option is useful for me.
