In my application, I use jsf & richfaces, I want to display a generated pdf in web browser , I have generated this PDF in serverside and it is available in ServletResponse, but I am unable to display it in my web page.
I have tried this question but, it did not solve my problem.
Is there any libraries or special ways to do this?
What I have tried to do is given below.
<h:commandLink rendered="#{ fileImportOptionsViewBean.isFileExist(status.myPdf) }" action="#
{fileImportOptionsViewBean.downloadFile(satus.myPdf)}" target="_blank">
<h:graphicImage url="../../resources/xyz/icons/pdf.png" /></h:commandLink>
downloadFile method
public void downloadFile(String filePath){
try {
File file=new File(filePath);
if(file.exists()){
FacesContext fc=FacesContext.getCurrentInstance();
ExternalContext ec=fc.getExternalContext();
ec.responseReset();
ec.setResponseContentType("application/pdf");
ec.setResponseHeader("Content-Disposition", "inline; filename=\"" + file.getName() + "\"");
ec.setResponseBufferSize(8192);
OutputStream output = ec.getResponseOutputStream();
URL url = file.toURL();
try(
BufferedInputStream bis = new BufferedInputStream(url.openStream());
BufferedOutputStream bos = new BufferedOutputStream(output);
){
byte[] buff = new byte[8192];
int bytesRead;
while (-1 != (bytesRead = bis.read(buff, 0, buff.length))) {
bos.write(buff, 0, bytesRead);
}
}
fc.responseComplete();
}
} catch (Exception e) {
}
}
Any help is appreciated,Thanks.
I don't see anything wrong with your current setup.Most probably the problem lies in your XHTML page and something is causing your h:commandLink not to fire the event.Please refer this post for further details,surely this will be of some help to you.
