    Post Help!, newbie, interested in Java, Very simple code, completely stuck!

    //This code reports a non static method and I have not got a clue why, can anyone help?

    createSite is not a static method, so you can't call it without having an instance of that class.

    Also, that doesn't look like "very simple code" to me. "Hello world" is very simple code. If you're new to Java I suggest you read some basic tutorials first.

    The error message says that at line 41 in your program you call a method: createSite.
    The code at Line 41 is in a static method. The method called is not a static method and can only be used when an object exists.
    Either make the method being called static, or create an instance of the object and use that instance to call the method.
    Also See OutputStream's response.
