problem in getting the html when i hit jsp

I need to get the html in string when i hit the hit the jsp in servlets
basically i need to put the output of jsp in pdf file
when i hit one link i need to download that data in pdf file.
Iam using itextpdf.
sample code

pResponse.setContentType("application/pdf");
((HttpServletResponse) pResponse).setHeader("Content-Disposition", "attachment; filename=report.pdf");

//Get the output stream for writing PDF object
OutputStream outStream=pResponse.getOutputStream();
ByteArrayOutputStream baosPDF = new ByteArrayOutputStream();

try {
Document document = new Document();
PdfWriter docWriter =PdfWriter.getInstance(document, baosPDF);
document.open();
String jspPath="C://workingcode//ATG//ATG10.1.1//Mergeingcode//atg//code//src//main//atg//myproj//Storefront//j2ee-apps//Storefront//store.war//myaccount//v2//sampledownload.jsp";
String csspath="C://workingcode//ATG//ATG10.1.1//Mergeingcode//atg//code//src//main//atg//myproj//StaticContent//css//test.css";

File file= new File(jspPath);

/ document.add(new Paragraph(org.apache.commons.io.FileUtils.readFileToString(file)));
// step 4
// XMLWorkerHelper.getInstance().parseXHtml(docWriter, document,new FileInputStream(jspPath),new FileInputStream(csspath) ,null ,new XMLWorkerFontProvider());

System.out.println( "PDF Created!" );

pRequest.getRequestDispatcher(jspPath).include(pRequest, responseWrapper);
String content = responseWrapper.getWriter().toString();

System.out.println("Output : " + content);

document.add(new Paragraph("ssss"));

document.add(new Paragraph(content));

document.close();
docWriter.close();

baosPDF.writeTo(outStream);
outStream.flush();
}
catch (DocumentException exc){
throw new IOException(exc.getMessage());
}
finally {
outStream.close();
}

i need to convert the sample download.jsp to html so that i can parse

// XMLWorkerHelper.getInstance().parseXHtml(docWriter, document,new FileInputStream(jspPath),new FileInputStream(csspath) ,null ,new XMLWorkerFontProvider());

Any help is appreciated
