    Re: About Exception Error in j2me

    You are calling:

    Code:
    Image img = Image.createImage("/someimage.png");
    There are two possibilities:

    1. the image file is not in the JAR

    2. the image is too large to load

    Check in your JAR file, and make sure the image file actually exists. File names in JARs are case-sensitive (like Unix file names), so make sure they match exactly. Check you have a leading "/" in front of the file name in the Java code.

    Cheers,
    Graham.

    Hi abhi,
    Image object is not created. some poroblem in getting image streams. to know this issue correct try to create an image from the res folder of the application like this im = Image.createImage("/image_bw.png");. check if this error comes. if not then it is from getting image streams

    Regards,
    Senthil
