I am trying to stream a PDF to a new browser window. I can get this to work,
but the strange thing that happens is that a new browser window gets opened,
but instead of the PDF geting displayed inside the browser window, it is opened
separately by Adobe Acrobat. So, the user is forced to close two windows, the
Adobe Acrobat window and the blank Browser window. I have gone over my code but
have never seen any behavior quite like this.
What will cause a new browser window to open up, but still open Adobe Acrobat
outside of the browser?
Any thoughts on why this is happening?
Could this have something to do with using the seam link or is this more likely
a JSF response issue?
My code is as follows:
JBoss Seam Link:
<s:link id="link1"
| action="#{reportDocumentBean.viewPhysicalDamagePDF}"
target="_blank">
| <h:outputText value="Print" />
| </s:link>
here is the heart of the Print Report Bean's method:
| HttpServletResponse response = (HttpServletResponse)
faces
| .getExternalContext().getResponse();
| response.setContentType("application/pdf");
| response.setContentLength(pdf.length);
| response.setHeader("Content-disposition",
"attachment;filename=\""
| + reportName+"crystalreport.pdf" +
"\"");
|
| ServletOutputStream out;
| out = response.getOutputStream();
| out.write(pdf);
| out.flush(); //new
|
| out.close();
| bais.close();
| reportClientDocument.close();
| faces.responseComplete(); //new
|
|
Here is the entire method incase you need to see the context of the snippet
above.
| private void viewPDF(String reportName, String fullClassName, String
tableAlias, String subreportTableAlias, List dataSet)
| {
| FacesContext faces = FacesContext.getCurrentInstance();
|
| try {
| ReportClientDocument reportClientDocument = new
ReportClientDocument();
| String report = reportName;
| //String report = "RDC_To_CR.Net.rpt";
| reportClientDocument.open(report, 0);
|
|
| List<CrystalDTO> crystalTranferObjects = new
ArrayList<CrystalDTO>();
|
| //fill dto
| CrystalDTO crystalDTO1 = new CrystalDTO(dataSet,
| fullClassName,
| tableAlias, subreportTableAlias);
| crystalTranferObjects.add(crystalDTO1);
|
|
|
| Iterator crystalDTOIterator=
crystalTranferObjects.iterator();
| while(crystalDTOIterator.hasNext())
| {
| CrystalDTO
dto=(CrystalDTO)crystalDTOIterator.next();
|
|
ReportCreator.passPOJO(reportClientDocument, dto.getDataSet(),
dto.getClassName(), dto.getTableAlias(), dto.getSubreportName());
| }
|
| ByteArrayInputStream bais;
| bais = (ByteArrayInputStream) reportClientDocument
|
.getPrintOutputController().export(ReportExportFormat.PDF);
| byte[] pdf = new byte[bais.available()];
| bais.read(pdf, 0, bais.available());
|
| HttpServletResponse response = (HttpServletResponse)
faces
| .getExternalContext().getResponse();
| response.setContentType("application/pdf");
| response.setContentLength(pdf.length);
| response.setHeader("Content-disposition",
"attachment;filename=\""
| + reportName+"crystalreport.pdf" +
"\"");
| ServletOutputStream out;
| out = response.getOutputStream();
| out.write(pdf);
| out.flush(); //new
|
| out.close();
| bais.close();
| reportClientDocument.close();
| faces.responseComplete(); //new
|
| }
|
| catch (ReportSDKException e) {
| e.printStackTrace();
| } catch (IOException e) {
| // TODO Auto-generated catch block
| e.printStackTrace();
| } catch (ClassNotFoundException e) {
| // TODO Auto-generated catch block
| e.printStackTrace();
| }
| faces.responseComplete();
| }
|
