private void impressao(){
    int impressao = JOptionPane.showConfirmDialog(null, "Deseja gerar tela de impressão?", "Atenção", JOptionPane.YES_NO_OPTION);
    if (impressao == JOptionPane.YES_OPTION) {
            String recibo = NumRecibo.getText();
            
        try {
            HashMap filtro = new HashMap();
            filtro.put("recibo",recibo);
            
            JasperPrint print = JasperFillManager.fillReport("C:\\Program Files\\Aluguel Program\\src\\br\\com\\aluguel\\reports\\recibo1.jasper", filtro, conexao);
            JasperViewer.viewReport(print, false);
            
        } catch (Exception e) {
            JOptionPane.showMessageDialog(null, "Error: "+e);
            
        }
        
    }
}

Bom dia. Estou querendo gerar um recibo na minha aplicação, não está gerando. Quando faço o teste pelo jaspersoft ele reconhece os parametros e gera normalmente, mas pela aplicação não vai.
