I have created pdf using IText library Now I want when the user clicks on the button ,it should prompt a save dialog box to the user to allow to browse the destination location to store the file.
Now My code looks like
Document document = new Document();
try {
FacesContext context = FacesContext.getCurrentInstance();
HttpServletResponse response = (HttpServletResponse) context.getExternalContext().getResponse();
response.reset();
response.setContentType("application/pdf");
response.setHeader("Content-Disposition", "attachment; filename=ABC.pdf");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);
response.setHeader("Pragma", "No-cache");
PdfWriter.getInstance(document, response.getOutputStream());
document.addTitle("Form");
document.addSubject("Form");
document.open();
Paragraph paragraph12 = new Paragraph("FORM",
FontFactory.getFont(FontFactory.HELVETICA,
18, Font.BOLD, new CMYKColor(0, 255, 255, 17)));
Chapter chapter1 = new Chapter(paragraph12, 1);
paragraph12.setSpacingAfter(25);
paragraph12.setAlignment(Element.ALIGN_CENTER);
document.add(paragraph12);
// Centered
Chunk underline = new Chunk(AppNo);
underline.setUnderline(0.2f, -2f);
Paragraph paragraph = new Paragraph("Application No:");
paragraph.add(underline);
paragraph.setAlignment(Element.ALIGN_LEFT);
paragraph.setSpacingAfter(20);
document.add(paragraph);
// Left
paragraph = new Paragraph("To,");
paragraph.setAlignment(Element.ALIGN_LEFT);
document.add(paragraph);
// Left with indentation
paragraph = new Paragraph(
"");
paragraph.setAlignment(Element.ALIGN_LEFT);
document.add(paragraph);
Paragraph paragraph2 = new Paragraph(
"Subject: ");
paragraph2.setSpacingAfter(15);
paragraph2.setSpacingBefore(15);
paragraph2.setAlignment(Element.ALIGN_LEFT);
paragraph2.setIndentationRight(50);
document.add(paragraph2);
Paragraph paragraph3 = new Paragraph("I ");
String laName=deaclarationOpr.getDeclarationDetailsobj()
.getLaName();
if(laName!=null){
Chunk name = new Chunk(laName);
name.setUnderline(0.2f, -2f);
paragraph3.add(name);
}
paragraph3.add(" request you to process the Application ");
paragraph3.add(underline);
paragraph3.add(" for product ");
String productName=deaclarationOpr
.getDeclarationDetailsobj().getProductName();
if(productName!=null){
Chunk product = new Chunk(productName);
product.setUnderline(0.2f, -2f);
paragraph3.add(product);
}
paragraph3
.add("");
paragraph3.setSpacingAfter(15);

document.add(paragraph3);
Paragraph paragraph4 = new Paragraph(
"");
String code=deaclarationOpr
.getDeclarationDetailsobj().getAdvisorCode();
if(code!=null){
Chunk advisorCode = new Chunk(code);
advisorCode.setUnderline(0.2f, -2f);
paragraph4.add(advisorCode);
}
paragraph4
.add("");
paragraph4.setSpacingAfter(15);
paragraph4.setSpacingBefore(15);
paragraph4.setAlignment(Element.ALIGN_LEFT);
paragraph4.setIndentationLeft(50);
paragraph4.setIndentationRight(50);
document.add(paragraph4);
Paragraph paragraph5 = new Paragraph(
"");
paragraph5.setSpacingAfter(15);

document.add(paragraph6);
Paragraph paragraph7 = new Paragraph("Date: ");
DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
// get current date time with Date()
Date date = new Date();
paragraph7.add(dateFormat.format(date));
paragraph7.setSpacingBefore(15);
paragraph7.setIndentationLeft(50);

document.add(paragraph7);
Paragraph paragraph8 = new Paragraph("Name of the Proposer: ");
String propoer=deaclarationOpr
.getDeclarationDetailsobj().getProposerName();
if(propoer!=null){
Chunk proposerName = new Chunk(propoer);
proposerName.setUnderline(0.2f, -2f);
paragraph8.add(proposerName);
}

document.add(paragraph9);
document.close();

And the above code is written in the method of Backing Bean class
and invoked
<tr>
<td align="center"><a4j:commandButton

action="#{declarationBB.convertToPdf}"></a4j:commandButton></td>
</tr>
I get below in the new page
