    Default Help with Java

    When I tried to load a feature on a online college course I'm currently taking, I got this error that I think is caused by Java's inability to define the category of the object it needs to display. Here is the code in "Details":

    Code:
    load: class blackboard.plugins.virtualclassroom.ui.Titlebar.class not found.

    Please decipher the code and find a way to help me figure out my problem and a solution to it. I can load the Yahoo Games page, which require the product I need to use for my desires. I just cannot load that feature in the online class I'm currently taking... I tried looking on the Web, can't easily find a solution to my problem. Just so you know, I'm currently using Firefox. If I was using IE, I think the answer would've been there, but I'm not sure on that. If you can, you may post URLs that could help me figure out why I keep getting the exceptions I'm getting in the "Details". Thanks!
