    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:

    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!

    Your connection is timing out, causing some classes not to load. Not sure how to help you with this one, it might be your internet or it might be the server.

    Why in tech part of this forum, Java is so seldom. I just have a question about it.
