    Question Invalid jar file.

    Hi.
    I am using exclipse 3.1 with Sun WTK 2.2.
    after creating my own profile which uses only the following:
    * Cldc 1.0
    * Midp 2.0
    * MMapi

    I have created a package (Jar + Jad) however my Nokia 6680 didn't accept it and gave me "invalid file" error message.

    Nokia 6600 does the same thing.

    I have tried to make an "Hello world" using the WTK 2.2 profile of MIDP 1.0 only (cldc 1.0) and I got the same message !

    I Also tried to build my application with the KToolbar of the wtk22 and I got an error message saying that I need to use JDK version 1.4 or aobve.
    I am using JDK version 1.5

    Any ideas ?
    Did someone here managed to make a working JAR file with the eclipse 3.1 and WTK 2.2 ?

    Re: Invalid jar file.

    I am sending the jar via bluetooth after creating it using the option "Create package" which is available from the J2ME menu.

    I have also dscovered that the problem is casued by the fact that the following line is missing from the METAINFO.

    line: "MIDlet-1: midlet_class_name, , package.midle_class_name"
    (the line should be included in the jad without the "" ).

    After entering this line manualy to the JAR files metainfo or entering manualy to the JAD file so the "creating package" option will generate a jar file that contains this line - the JAR worked on the target device.

    any idea how to make the WTK22 include this line autoamticly ?

    Shai . K
