When I transfer this file to device (Nokia 3310, Nokia 6610, SonyEricsson K700) using data cable, the abc.jar is working properly. I mean file is known and installed normally then I can use the application.
But I try putting the file in some server (http://www.domainName.com/abc.jar) and I use application manager (in devices) to download the file and install, the file is �Unknown�.
What�s happen? Why? Is this only use data cable to transfer and install the jar file?
the first time i try to open file through Device (Nokia) input url: "http://MyDomain.com/abc.jad" and there is working properly. the device display information about: Application name, Size, Vendor, and version. then i just click "ok" button, then the display show the device is download application progress. afterward, the device system response is "Invalid File".
In my experience Nokia Handsets return Invalid file in the following cases.
- Your server doesnt have the valid mime type for jar files. (this works on some Nokia handsets) - The jar size attribute in the jad file does not have the right value. - The other required attributes (e.g Midlet-1 etc) are not the same in the jar manifest as in the jad file.
Does the phone give an error code along with the error message.
