I am havnig some problems downloading to V600 handset over-the-air. It starts downloading and then says "Download Failed". I have reviewed the V600 documentation and the jar size exactly matches what is in the JAD. I have not had issues with the same files and all other devices so I was wondering if there were any specific JAD requirements for this device.

Motorola V400/600 are MIDP2.0 phones

So what does that have to with the JAD requirements? It was my understanding that all MIDP 2.0 devices are backwards compatible with MIDP 1.0. I'm building my project as a MIDP 1.0 application in the Sun's WTK but I haven't had an issue loading this on other MIDP 2.0 devices.

I don't know your specifics. However, as far I know not all MIDP1.0 app can run on Nokia6600. On V400/600, we had no problem to run our MIDP2.0 app. There certainly exist some subtle backwards compatibilty problems.

Roseanne,

Thank you for that information. Do you know if you compiled and packaged your application as a MIDP 1.0 or MIDP 2.0 app? We're are packaging our application as a MIDP 1.0 (using Sun's WTK) and trying to distribute to MIDP 2.0 phones. We are doing this a MIDP 2.0 version won't run on a MIDP 1.0 handset and we only want one set of jar/jad files.

Thanks again,
Greg
