How to display pdf on JSF - jsf

Question

Hi my code is as follows:
public StreamedContent getTempPdfFile() throws IOException {
File testPdfFile = new File("D:\\AFC150_20180819_0103.pdf");
streamedContent = new DefaultStreamedContent(new FileInputStream(testPdfFile), "application/pdf",
"AFC150_20180819_0103.pdf");
return streamedContent;
}
<h:panelGrid columns="1" cellpadding="5">
<p:media value="#{realReport.tempPdfFile}" player="pdf" width="1000px" height="300px">
<f:param name="id" />
</p:media>
</h:panelGrid>
But the PDF file is not getting displayed on the page.

Answer 1

Here is my sample, hope it helps, the code has the inline and attachment:
void sendBackPDFToClient()
{
//File temp = File.createTempFile(fileName, ".pdf");
File testPdfFile = new File("D:\AFC150_20180819_0103.pdf");
FacesContext fc = FacesContext.getCurrentInstance();
ExternalContext ec = fc.getExternalContext();
ec.responseReset();
ec.setResponseContentType("application/pdf");
ec.setResponseContentLength((int)testPdfFile.length());
//Inline
//ec.setResponseHeader("Content-Disposition", "inline; filename=\"" + testPdfFile.getName() + "\"");
//Attach for Browser
ec.setResponseHeader("Content-Disposition", "attachment; filename=\"" + testPdfFile.getName() + "\"");
OutputStream output = ec.getResponseOutputStream();
Files.copy(testPdfFile.toPath(), output);
fc.responseComplete();
}

Have you tried the Document Viewer component of PrimeFaces Extensions?
I think its much easier to use than p:media and offers more features including ability to load it from a URL, a Stream, or a Resource. That basic example shows you how to do it with all 3 types.
JAVA:
public StreamedContent getTempPdfFile() throws IOException {
File testPdfFile = Paths.get("D:\\AFC150_20180819_0103.pdf").toFile();
return new DefaultStreamedContent(new FileInputStream(testPdfFile), "application/pdf",
"AFC150_20180819_0103");
}
XHTML:
<pe:documentViewer height="500" width="1000" value="#{realReport.tempPdfFile}"/>
