Re: ImageReader not working on fedora 6

Hi Bhavya,
it seems you are missing a class file from the SUN JDK. I guess your application is not running on the SUN JVM? What kind of JVM are you using? I guess Fedora ships with it's own java version. 

Kind regards,

    Hi Bhavya,

    did you check your log files? It might tell you the reason. The other
    thing I can think of is that you do not have window manager on you
    fedora box, so you will have to run your java application in
    headless mode.

    "java -Djava.awt.headless=true"

    This happens sometimes when you switch from a development 'windows'
    environment to a linux dedicated server environment.

    Kind regards,

    Jeroen Reijn

    ps. Please try to send you question to one mailinglist instead of
    cross-posting it to 4.
