Export and Print icons missing from report viewer

Question

I'm currently embedding crystal within a wicket application in which I'm making use of the getHtmlContent() method to retrieve the report's HTML.  For whatever reason, I'm not able to get either the export or print icons (on the top left side of the viewer).  Is this because I'm using the getHtmlContent() method or do I have something misconfigured somewhere?  Setting the setHasExportButton(true) and setHasPrintButton(true) on the report viewer object has no effect. 
If I run the same report using the generated JSP outside of my application (within tomcat), I see the export/print buttons.  I notice the JSP makes use of the processHttpRequest() method.  Any help will be greatly appreciated.
Thanks!

Hi Louis
- The getHtmlContent() method handles the user's request to generate the HTML for the report and returns the HTML as a String.
Note: Either the getHtmlContent method or the processHttpRequest method can be used to handle the user's request to generate the HTML for the report, depending on how you write your JSP. If the viewer's content is displayed more than once, then the getHtmlContent method is more efficient, because the request is processed once and the resulting HTML string can be used multiple times. In this case, you must set the content type of the HTML, as recommended in the table. Additionally, using getHtmlContent sets setOwnPage to false and disables exporting and printing.
- The setOwnPage(true) and  processHttpRequest() method should be used if you want the export and print button to appear in the report viewed through Crystal Report Viewer.
Following is the snippet of code which shows you how to use these 2 methods.
//Get the IReportSource object from sesion and pass it to the viewer
     IReportSource reportSource = (IReportSource)session.getAttribute("reportSource");
Create the viewer and render the report -
     //create the CrystalReportViewer object
     CrystalReportViewer oCrystalReportViewer = new CrystalReportViewer();
     //set the reportsource property of the viewer
     oCrystalReportViewer.setReportSource(reportSource);
     //set viewer attributes
     oCrystalReportViewer.setOwnPage(true);
     oCrystalReportViewer.setOwnForm(true);
     //set the CrystalReportViewer print mode
     //oCrystalReportViewer.setPrintMode(CrPrintMode.ACTIVEX);
     oCrystalReportViewer.setPrintMode(CrPrintMode.PDF);
     //process the report
     oCrystalReportViewer.processHttpRequest(request, response, getServletConfig().getServletContext(), null);
Hope this helps you .
