Pdf reports on webtoGo ? urgent plz

Question

Hi ,
I developed a webtogo offline application and successfully generated the jasper pdf reports on local jdeveloper.Now i am publishing the same on olite server.
The pdf report first save in /report folder and then open on popup in a new window(works fine on local machine with jdev).
Now i have a doubt if the same works on server too?
Does my code works or not?
becoz i am getting some null pointer exception.The same code i have deployed which is working on local machine.
error log:
java.lang.NullPointerException

Servlet.java --------------------------------
public class ReportServlet extends SEWControllerServlet { private static final String CONTENT_TYPE = "text/html; charset=windows-1252"; public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { this.doPost(request,response); } public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String key4nav = request.getParameter(SEWConstants.SEW_KEYS.PARAM_KEY); System.out.println("key4nav..report servlet"+key4nav); String key4next = key4nav; System.out.println("key4next"+key4next); boolean statusFlag = false; JasperReport jasperreport; Connection conn = null; try { if(key4nav.equals(SEWConstants.MODULE_PURCHASING.REPORT)) { String submitBtn = request.getParameter("submit"); String reportName = request.getParameter("reportName"); String location = SEWLoggedInUser.getLocation(); Map parameters = new HashMap(); if(request.getParameter("reportName").equalsIgnoreCase("vendorReport")) { String poNumber = request.getParameter("poNumber"); String receiptNumber = request.getParameter("receiptNumber"); String advisedBy = request.getParameter("advisedBy"); String preparedBy = request.getParameter("preparedBy"); String reportPath= request.getRealPath("/reports"); String reportImagepath= request.getRealPath("/images"); System.out.println("reportImagepath&gt;&gt;"+reportImagepath); jasperreport = JasperCompileManager.compileReport(reportPath+ "/vendor_report.xml"); parameters.put("poNumber",poNumber); parameters.put("receiptNumber",receiptNumber); parameters.put("location",location); parameters.put("advisedBy",advisedBy); parameters.put("preparedBy",preparedBy); parameters.put("reportImagepath",reportImagepath); conn = SEWConnectionManager.getConnection(); // response.setContentType("application/pdf"); // response.setContentLength(0); // ServletOutputStream out = response.getOutputStream(); JasperPrint jasperPrint = JasperFillManager.fillReport(jasperreport, parameters, conn); byte[] bytes= JasperExportManager.exportReportToPdf(jasperPrint); response.setContentType("application/pdf"); //response.addHeader("Content-Disposition", "inline;"); //open in current window response.setHeader ("Content-Disposition","attachment;filename=\"report.pdf\""); //open in new browser window response.setContentLength(bytes.length); ServletOutputStream ouputStream = response.getOutputStream(); ouputStream.write(bytes, 0, bytes.length); ouputStream.flush(); ouputStream.close(); if(conn!=null){ conn.close(); } }
Here i am the report Image and report xml path using
String reportPath= request.getRealPath("/reports");
String reportImagepath= request.getRealPath("/images");
Does this work on webtogo?How does it look for the location of reports folder and then the xml file?
Can you tell me how you are getting pdf in your application
