    HELP!!! load: class vscroller.class not found.

    Hello!

    This is my first time in this forum and i hope anyone can help me.
    When i open some http pages java doesn't works and i'm able to see the following message at java console:

    load: class vscroller.class not found.
    java.lang.ClassNotFoundException: vscroller.class
    at sun.applet.AppletClassLoader.findClass(Unknown Source)

    Please can anyone tell me what's wrong and how can i solve the problem. I think it's important to say that i already tried to install java sun a few times...but the problems seems to be the same.

    Thanks a lot for your help.

    I don't know about the vscroller class. You will have to look in the jar files that were used when the program was compiled and find that class. You can use the WinZip program to look at jar file contents.
    When you find the jar file with that class, you will have to add it to the classpath for the applet. That's done by using the archive= attribute of the <APPLET tag.
    If vscroller.class is not in a jar, then you could add that class file to the same directory on the server where the applet's class is.
