Converter Txt em Pdf com Ireport

Java

18/11/2014

Ola boa noite eu tenho um arquivo txt com varias linhas e gostaria de converte-lo para um arquivo pdf usando o ireport
eu abro o arquivo, leio o txt intero armazeno dentro um array list porem quando é na hora do ireport gera o arquivo ele gera em branco, o array list ele contem dados que 


List<String> listaTexto = new ArrayList<>();
        BufferedReader bufferedReader = new BufferedReader(fileReader); //aqui ele vai receber o arquivo 

        String linha = "";
        int i = 1;
        try {
            while ((linha = bufferedReader.readLine()) != null) {
                listaTexto.add(linha);
                i++;
            }
        } catch (IOException e1) {
            System.out.println("Nao consegui ler o arquivo " + e1.getMessage());
            e1.printStackTrace();
        }


e o meu report
esta somente com a band detail com o componente List usando a expresao $F

e passo da seguinte forma o ArrayList
 Map parameters = new HashMap();
        parameters.put("MinhaLista", listaTexto);
        try {
            impressao = JasperFillManager.fillReport(layoutImpressao, null, new JRBeanCollectionDataSource(listaTexto));
        } catch (JRException ex) {
            Logger.getLogger(PrincipalJorcamento.class.getName()).log(Level.SEVERE, null, ex);
        }

Em nenhum omento estou vendo vocÊ passar a variável "parameters" para o fillReport().
Tente assim:

impressao = JasperFillManager.fillReport(layoutImpressao, parameters, new JRBeanCollectionDataSource(listaTexto));

e o codigo java assim:
final Map<String,Object> parameters = new HashMap<String,Object>();
        parameters.put("minhalista", listaTexto);
        try {
            impressao = JasperFillManager.fillReport(layoutImpressao, parameters, new JREmptyDataSource());
        } catch (JRException ex) {
            Logger.getLogger(PrincipalJorcamento.class.getName()).log(Level.SEVERE, null, ex);
        }

Este erro ocorre antes de executar o relatório ou durante a execução do mesmo ? Verifica se você está passando um objeto do tipo MAP<String,Object> e não um List ou ArrayList.
