    Hi

    How do you produce .jad file ? -- definitely it is incorrect since your application can be installed normally from .jar file. In that sense issue#1 and 2 are the same.

    You can test your application installation on wide range of devices by using Remote Device Access service -- that is free to use

    Thank you for an answer,

    We use netbean to produce both .jar and .jad files. For we've tested our app in RDA, we think that the problem is that .jad used in installation cannot find .jar file because it's not sit next to it! If we just try to install with .jad file first then .jar is not uploaded into the machine. Of course, we cannot install the app because installation file is actually .jar file. So after tried both files .jad can install our app without any error message. (I think the message should be 'cannot find .jar file' instead. )

    For the certification error, We've found it in non-touchscreen devices. Therefore, we remove attribute MIDlet-Touch-Support from our app and it works. So we have our app 'for touchscreen' and 'without touchscreen' now. I think that Nokia shouldn't be too restrict about submitting and installing application if they cannot indicate clearly what's the problem.

    However, we cannot test some indicated devices because they aren't in RDA.
