Erro no JFreeChart

[jigsawPJ]

Help!!!

Preciso de uma força para fazer um relatorio com graficos utilizando o jfreechart.
OBS: Utilizei o mesmo exemplo de um tutorial que tem no proprio site do Portal Java, mas quando fui testar no browser utilizando um servlet
deu o mesmo erro de quando eu teste com o iReport.
erro------->
