Arquivo Discussoes de Programacao e Tecnologia Olá …
eu estou fazendo um relatorio utilizando o ireport com o java beans e eu gostaria de fazer dois relatorios na mesma página.
Li em outro topico que daria para fazer utilizando um subrelatorio , criei um subrelatorio , porem quando eu vou visualizar não aparece nada.
Se alguem poder me ajudar ficarei muito grata . 
Quando eu precisei este post aqui me ajudou muito
