Bom Dia Pessoal!
Seguinte, estou tentando exportar alguns dados para excel, nos testes ele funciona legal eu fiz assim nos testes:

ArquivoDAO arquivoDAO = new ArquivoDAO();
createXls("C:/Documents and Settings/WinXP/Desktop/ola", arquivoDAO.valor());

e pra valer eu fiz isso:

ArquivoDAO arquivoDAO = new ArquivoDAO();

util.Exportar.exportarXLS(Arquivo.getSelectedFile().toString(), arquivoDAO.valor());

mas dá esse erro:

erro:

Isso acontece quando tento passar a List do meu banco, será que tem ha ver com a questão de eu estar usando arquivoDAO.valor(); para mostrar no meu grid e a virtual ficar cheia e morrer?
