I had generate a report with IREPORT 3.7 . I have now a .jasper file.
I would want to be able to execute (show) it with a jsp file or servlet.
My generated report not use sql queries, only it need 2 parameters. i think to pass these parameters from 2 text input in other jsp file.
The code that I am trying is :

    Document   : reporte

            /*Parametros para realizar la conexión*/
            Connection conexion;
            conexion = DriverManager.getConnection("jdbc:mysql://localhost:3306/gae", "root", "");
            /*Establecemos la ruta del reporte*/
            File reportFile = new File(application.getRealPath("reportes//prueba1.jasper"));
            /* No enviamos parámetros porque nuestro reporte no los necesita asi que escriba cualquier cadena de texto ya que solo seguiremos el formato del método runReportToPdf*/
            Map parameters = new HashMap();
            parameters.put("cedula", "cedula");
            parameters.put("nombre", "nombre");
            /*Enviamos la ruta del reporte, los parámetros y la conexión(objeto Connection)*/
            byte[] bytes = JasperRunManager.runReportToPdf(reportFile.getPath(), parameters, conexion);
            /*Indicamos que la respuesta va a ser en formato PDF*/
            ServletOutputStream ouputStream = response.getOutputStream();
            ouputStream.write(bytes, 0, bytes.length); /*Limpiamos y cerramos flujos de salida*/
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
        <h1>Hello World!</h1>

Anyone know other method without to use connection?? This code give me error in the line 32!!!

Muchas Gracias

There are many overloaded runReportToPdf() methods for the JasperRunManager object including the one without connection. Go through the JasperRunManager APIs for more details

Hi all,
Please include
jasperreports-1.0.2.jar and jasperreports-1.0.2-applet.jar
in your WEB-INF/lib directory
to solve this issue.

You can get these jar files from "jasperreports-1.0.2\dist" which is extracted from "jasperreports-1.0.2-project.zip" file..
