How can I set prameters on a report source

Question

HI,
I'm writing a JSF application that uses Crystal Reports. I am able to show the report with this tag.
<bocrv:reportPageViewer viewerName="CrystalViewer" reportSource="#{crystalReportManager.getReportSource('CrystalReport1.rpt')}" allowParameterPrompting="on"/>
The code for the crystalReportManager.getReportSource looks like this
public Object getReportSource(String reportPath)
        try
            IReportSourceFactory2 rptSrcFactory = new JPEReportSourceFactory();
            Object rptSrc = rptSrcFactory.createReportSource(reportPath, Locale.instance());
            return rptSrc;
        catch (Exception e)
            e.printStackTrace();
        return null;
I would like to set the properties so they will promt but I can't find any documentation on how to add a ParameterFieldDiscreteValue on a ReportSource object.
Thank you.
Matthew

You're using the JSF report viewer tag to display reports, and you're using the JRC to retrieve the report.
The JPEReportSourceFactory is a fairly old method, commonly used back in JRC 10 when there wasn't a ReportClientDocument.
If you're using a newer version, then you can access the report via the ReportClientDocument, then set the parameters before passing it to the viewer, via ReportClientDocument.getDataDefController().getParameterFieldController().setCurrentValues(...).
