Pessoal estou usando a dica um amigo aqui do fórum para mostrar relatórios em pdf. usando o component jasperMaker.
O problema é q quando eu chamo o relatório de listagem de alunos ele não mostra … dá um erro…
alguém pode ajudar:?
Lógica:
public Download imprimir(){
return jasperMaker.makePdf("alunos.jasper", alunoDao.lista(), "alunos.pdf", true);
}
e ele me retorna isso aqui…
