How to create a PDF file using iText in memory and then show in a object into dialog primefaces, the user can download the report if wanted.
This is my code:
private StreamedContent file;
public StreamedContent getFile() {
return file;
}
public void setFile(StreamedContent file) {
this.file = file;
}
public void memoryReport() throws DocumentException {
try {
Document document = new Document(PageSize.LETTER);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PdfWriter writer;
writer = PdfWriter.getInstance(document, baos);
document.addTitle("This is a title.");
document.open();
document.add(new Paragraph("This document was created successful"));
document.close();
writer.close();
//String fileName = "Andy";
InputStream stream = new ByteArrayInputStream(baos.toByteArray());
//file = new DefaultStreamedContent(stream, "application/pdf", fileName);
file=new DefaultStreamedContent(stream, "application/pdf");
} catch (Exception ex) {
ex.getMessage();
}
}
