I'm having trouble embedding dynamic PDF within a specified area of a JSP using the <embed> tag.
My JSP code resembles the following:
<embed
src="<%=request.getContextPath()%>/controller/Administration/administrator_v
iewcreate_invoice.jsp?Embed_Invoice=Embed_Invoice" width="100%"
height="100%" type="application/pdf" />
When the JSP loads, this code fires off a request to the controller servlet
which uses an action class to build a very basic (at the moment) pdf stream.
A snippet of the action class code snippet is below:
public String createPDFInvoice( HttpServletRequest request,
HttpServletResponse response ) {
HttpSession session = request.getSession();
Date todaysDate = new Date();
Customer customer =
(Customer)session.getAttribute("CUSTOMER_TO_INVOICE");
Document document = new Document(PageSize.LETTER);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
try {
PdfWriter writer =
PdfWriter.getInstance(document,baos);
document.open();
document.add(new Paragraph("Invoice"));
document.add(new Paragraph(new Date().toString()));
document.add(new Paragraph(customer.getFullName()));
document.close();
response.setContentType("application/pdf");
response.setContentLength(baos.size());
ServletOutputStream out =
response.getOutputStream();
baos.writeTo(out);
out.flush();
} catch ( Exception e ) {
e.printStackTrace();
System.out.println("document: "+e.getMessage());
}
return("/Administration/administrator_viewcreate_invoice.jsp");
}
When the action class returns to the controller servlet, the following code
is executed:
requestedURL =
request.getContextPath()+"/Administration/administrator_viewcreate_invoice.j
sp";
try {
response.sendRedirect(requestedURL);
} catch( IOException ioe ) {
System.out.println("Problems redirecting admin view/create
invoice request in ControllerServlet.");
ioe.printStackTrace();
}
return;
If I scrap the <embed> tag and just use a <form> tag with a target of a new
window (target="_blank") the PDF shows up and takes up the entire browser
window. I would like to use the <embed> tag as it is described in iText in
Action (I've really enjoyed the book by the way - thus far) so that other
items on my JSP are also displayed in addition to the section that is
displaying the dynamic PDF. This is not working, however, using the code
above.
Some advice on where I have gone wrong here would be greatly appreciated.
Thanks,
Paul
