    Your code is very messy, over-complicated and full of mistakes + junk code. Try re-writing a simplified version of the code.

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

    Also copy the full text of the error message and pasted it here.
    If you don't understand my answer, don't ignore it, ask a question.
