Problems with jasper report pdf exporting

Question

Hello,
I coded a simple servlet to view a jasper report (created with iReport) after clicking on the right button in the jsp.
Here is the problem:
net.sf.jasperreports.engine.JRRuntimeException: Error evaluating expression :
     Source text : (java.awt.Image)it.businesslogic.ireport.chart.DefaultChartFactory.drawChart(new String[]{"chartName=Pie3D","depthFactor=0.2","titlePosition=1","width=245","plotBackground=[255,255,255]","serie1=SERIE_CONTA_RISPOSTE","serie0=SERIE_RISPOSTA","foregroundAlpha=0.33","tooltips=false","chartBackground=[255,255,255]","subtitle=","title=","legend=true","quality=2","height=168","antialias=true"}, (it.businesslogic.ireport.IReportScriptlet)$P{REPORT_SCRIPTLET})

     javax.servlet.http.HttpServlet.service(HttpServlet.java:689)
     javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
Here is the code:
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        byte[] byte_array = null;
        try{
            File reportFile = new File(this.getServletConfig().getServletContext().getRealPath("/reports/torte_call_center_agenzie.jasper"));
            if (!reportFile.exists()) throw new JRRuntimeException("File jasper non trovato");
            String nomeFile = reportFile.getPath();
            Map parameters = new HashMap();
            parameters.put("codice_questionario", "2");   //just for testing
            ConnettitiAlDB c = new ConnettitiAlDB();
            Connection conn = c.Connettiti(Conf.db_principale);
            byte_array = JasperRunManager.runReportToPdf(fullpath_filename, parameters, connessione);
            conn.close();
        catch(JRException e){
            e.printStackTrace();
        catch(SQLException e) {
            e.printStackTrace();
        response.setContentType("application/pdf");
     response.setContentLength(byte_array.length);
     ServletOutputStream ouputStream = response.getOutputStream();
     ouputStream.write(byte_array, 0, byte_array.length);
     ouputStream.flush();
     ouputStream.close();
     }Any suggestion? That would be vital to me!
Thanks in advance

Answer 1

catching the JRRuntimeException and printing its stacktrace i saw that the jfree chart lib was missing.
i put it in my libraries but now i got this error:
java.lang.NoSuchMethodError: com.lowagie.text.pdf.PdfContentByte.transform(Ljava/awt/geom/AffineTransform;)V

     javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
com.lowagie.text.pdf.PdfContentByte.transform is inside the iText library.
I had an old version so I updated it but nothing changed.
Any suggestion?
Thanks
