Getting the error while calling the report from oaf page

Question

Dear all
when i am calling the report from oaf page
if (pageContext.getParameter("PrintPDF") != null)
DataObject sessionDictionary =
(DataObject)pageContext.getNamedDataObject("_SessionParameters");
HttpServletResponse response =
(HttpServletResponse)sessionDictionary.selectValue("HttpServletResponse");
try
ServletOutputStream os = response.getOutputStream();
// Set the Output Report File Name and Content Type
String contentDisposition = "attachment;filename=EmpReport.pdf";
response.setHeader("Content-Disposition", contentDisposition);
response.setContentType("application/pdf");
// Get the Data XML File as the XMLNode
XMLNode xmlNode = (XMLNode)am.invokeMethod("getEmpDataXML");
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
xmlNode.print(outputStream);
ByteArrayInputStream inputStream =
new ByteArrayInputStream(outputStream.toByteArray());
ByteArrayOutputStream pdfFile = new ByteArrayOutputStream();
//Generate the PDF Report.
TemplateHelper.processTemplate(((OADBTransactionImpl)pageContext.getApplicationModule(webBean).getOADBTransaction()).getAppsContext(),
"XXCRM", "XXCRM_EMP",
((OADBTransactionImpl)pageContext.getApplicationModule(webBean).getOADBTransaction()).getUserLocale().getLanguage(),
((OADBTransactionImpl)pageContext.getApplicationModule(webBean).getOADBTransaction()).getUserLocale().getCountry(),
inputStream,
TemplateHelper.OUTPUT_TYPE_PDF, null,
pdfFile);
// Write the PDF Report to the HttpServletResponse object and flush.
byte[] b = pdfFile.toByteArray();
response.setContentLength(b.length);
os.write(b, 0, b.length);
os.flush();
os.close();
} catch (Exception e)
response.setContentType("text/html");
throw new OAException(e.getMessage(), OAException.ERROR);
pageContext.setDocumentRendered(false);
i am getting the error java.classcastexception at this line
DataObject sessionDictionary =
(DataObject)pageContext.getNamedDataObject("_SessionParameters");
