Report with charts not rendering from JSP

[adavidson]

Hi,

I have a report which in iReport works perfectly but when I try to put this into a JSP I cannot get anything to render at all. The main code in my JSP is:

       String reportFileName = application.getRealPath("/jsp/s.jasper");
        File reportFile = new File(reportFileName);
        if (!reportFile.exists())
            throw new JRRuntimeException("File "+reportFileName+" not found. The report design must be compiled first.");

        JasperPrint jasperPrint = JasperFillManager.fillReport(reportFileName, null, conn);
        JasperExportManager.exportReportToHtmlFile(jasperPrint, "c:\\s.html");

However the s.html it produces is virtually empty - it does get created when I run the above JSP but it produces a simple empty two column table (as attached) which of course is not what my report should look like!

Is the above code wrong? Any clues on how to make this work would be much appreciated as I've hunted around for days trying to find why this is happening.

Many thanks in advance,

Andrew.
