Export excel setting Page header once per report not working

Question

Hi All,
      I am having a java web application which creates the predefined template reports in pdf or xls or rpt format. I have a requirement where in case of XLS format, the page header should be displayed ONCE PER REPORT. I have Crystal Reports XI release 2 and Java 1.5.
    I am setting from java code
     formatType = IReportFormatOptions.CeReportFormat.EXCEL;
     reportFormat.setFormat(formatType);
     IExcelFormat formatExcel = (IExcelFormat)reportFormat.getFormatInterface();
     formatExcel.setExportPageHeaderFooter(IExcelFormat.CeReportExportHeaderFooterOption.ONCE);
I have installed a patch named Excel Export patch which basically sets some registry entries
Set HKEY_CURRENT_USER\Software\Crystal Decisions\10.0\Crystal
Reports\Export\Excel\PageAreaExportType to 0 for default behavior, 1 to display no page area, 2 to display page area once per report, and 3 to show the page area once per page.
Set HKEY_CURRENT_USER\Software\Crystal Decisions\10.0\Crystal
Reports\Export\Excel\ColumnWidthBaseArea to 0 for default behavior, 4 for column width based on detail
section.
I have set PageAreaExportType to 2 and ColumnWidthBaseArea to 0 and 4.
Still i see the page headers repeating on every page. Could you please help me in resolving the issue?
Thanks in advance.

Currently in our new version of java application, we are not using DHTML viewer. Predefined report templates are published on crystal server and from Java application, we send the report parameters to the crystal and also specify the format type.
Exporting excel from the crystal template is working fine with the page headers repeating only once (have set the page header show once per report option before exporting it to excel). But the same is not happening from the Java application. i have attached the required files to the message that i posted. If you have the access you can take a loot at them.
