Exception criando Imagem

Bom dia Galera !!!

Putz … Estou com um problema que eu não tenho nem idéia do que pode ser !! Vou tentar explicar.

Em uma página JSP existe o seguinte fonte:

Abaixo a classe que gera a Imagem!

Uma parte do fonte do Servlet.

response.setContentType&#40;"image/jpeg"&#41;;         
        Imagem_Pizza pie = new Imagem_Pizza&#40; valores, larg, alt, Color.WHITE, cores &#41;;
        OutputStream os = response.getOutputStream&#40;&#41;; 
        ImageIO.write&#40;pie.getBufferedImage&#40;&#41;, "jpeg", os&#41;; 
        os.close&#40;&#41;;

Uma parte do fonte da classe Imagem_Pizza

imageBuffer = new BufferedImage&#40; width, height, BufferedImage.TYPE_INT_RGB &#41;;
        Graphics g = imageBuffer.createGraphics&#40;&#41;;
        g.setColor&#40; background &#41;;
        g.fillRect&#40; 0, 0, width, height &#41;;
        int arc = 0;
        int&#91;&#93; sizes = calculateAngles&#40; values &#41;;
        for&#40;int i=0, j=0; i&lt;sizes.length; i++, j++&#41; &#123;
            if&#40; j==135 &#41; j = 0;
            g.setColor&#40; new Color&#40;cores&#91;j&#93;&#91;0&#93;, cores&#91;j&#93;&#91;1&#93; ,cores&#91;j&#93;&#91;2&#93;&#41; &#41;;
            g.fillArc&#40; 0, 0, width, height, arc, sizes&#91;i&#93; &#41;;
            arc += sizes&#91;i&#93;;
        &#125;

:arrow: Agora deixa eu explicar.
Eu utilizo o NetBeans para desenvolver. E no netbeans esta funcionando tudo perfeitamente … Não dá uma excessão qualquer … redodninho.

:arrow: Mas quando eu coloco as classes no Servidor de Produção (Uma maquina Linux, com o TomCat 5 e o Jdk 4 ), não funciona.

Gera a seguinte excessão.

Por favor, será que alguém tem idéia do por que que no NetBeans funciona e no Servidor não ???

Obrigado desde já …
