    Please edit your post and wrap your code with code tags:
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.

    Please copy the full text of the error message and paste it here.

    Please explain how the code is being executed. What PCs are used and what OSs are used?
    If you don't understand my answer, don't ignore it, ask a question.
