Missing image (html4botransp.gif) from the report

Question

Hi,
Our application connects to BO XI R2 server for displaying full client reports using JSP and servlet. Here is the code snippet, we are using to open report in servlet -
HttpSession session = httpservletrequest.getSession();
          IEnterpriseSession eSession=(IEnterpriseSession)session.getAttribute("EnterpriseSession");
          if (eSession != null)
               try
                    ReportEngines boReportEngines = (ReportEngines) eSession.getService("ReportEngines");
                    ReportEngine reportEngine = boReportEngines.getService(ReportEngines.ReportEngineType.FC_REPORT_ENGINE);
                    DocumentInstance doc = reportEngine.openDocument(new Integer(httpservletrequest.getParameter("docID")).intValue());
                    Report rep = doc.getReports().getItem(0);
                    HTMLView docHtmlView = (HTMLView)rep.getView(OutputFormatType.HTML);
                    String sHTMLView = docHtmlView.getContent();
                    httpservletresponse.setContentType("text/html;charset=ISO-8859-1");
                    PrintWriter pw = httpservletresponse.getWriter();
                    pw.println(sHTMLView);
               catch(SDKException ex)
The report opens successfully, however an 'image not found' error appears on the report opened in HTML page. On checking out the source of opened HTML page, noticed following <IMG> tag at 'image not found' position -
IMG SRC='getImage.jsp?sEntry=re0000000019f28e6b5990&name=html4botransp.gif' WIDTH='1280' HEIGHT='1810'
which image is 'html4botransp.gif'? Is it a BO specific image and if yes have we missed adding some library file?

Hi,
Any1 can suggest what's wrong in below code for image callback -
In 1st JSP -
ReportEngines boReportEngines = (ReportEngines) eSession.getService("ReportEngines");
          ReportEngine reportEngine = boReportEngines.getService(ReportEngines.ReportEngineType.FC_REPORT_ENGINE);
          session.setAttribute("ReportEngine", reportEngine);
          System.out.println("docID -
" + request.getParameter("docId"));
          DocumentInstance doc = reportEngine.openDocument(new Integer(request.getParameter("docId")).intValue());
          Report rep = doc.getReports().getItem(0);
          HTMLView docHtmlView = (HTMLView)rep.getView(OutputFormatType.DHTML);
          ImageOption     webiImgOpt = null;
          webiImgOpt = doc.getImageOption();
          webiImgOpt.setImageCallback("imageCallback.jsp");
          webiImgOpt.setImageNameHolder("image");
          webiImgOpt.setStorageTokenHolder("entry");
          String sHTMLView = docHtmlView.getContent();
In callback jsp file -
response.setContentType("image/gif");
String strEntry = request.getParameter("entry");
String strImageName = request.getParameter("image");
ReportEngine cdzReportEngine = (ReportEngine)session.getAttribute("ReportEngine");
DocumentInstance cdzDocument =  cdzReportEngine.getDocumentFromStorageToken(strEntry);
Image objImage = cdzDocument.getImage(strImageName);
byte[] abyBinaryContent = objImage.getBinaryContent();
ServletOutputStream objServletOutputStream =  response.getOutputStream();
response.setContentLength(abyBinaryContent.length);
objServletOutputStream.write(abyBinaryContent);
objServletOutputStream.flush();
objServletOutputStream.close();
I am still unable to display graphs and continue getting error for 'html4botransp.gif'. Both JSP files are present in same sub-directory.
Thanks
