How are you installing the app? Side-loading the jar directly on to the device via USB or Bluetooth? Some handsets don't support that. Try installing it over the air instead, by pointing the web browser to the JAD which should be online somewhere.

I already checked on some samsung mobiles. They could not allow direct installation through with bluetooth or with USB cable. Because they following certain security norms of java apps installation. You need to install it from WAP sites.
