Hi,
I�m trying to use this example to generate a pdf, but I�m not having
success with it.
How can I parse parameters from a jsp to this servlet, so this way I can
generate my pdf, not using the jsp but a servlet.
Thanks in advance.
Best Regards,
Roberto Godoy

try {
// take the message from the URL or create default message
String msg = (String)request.getParameter("msg");
if (msg == null || msg.trim().length() <= 0)
msg = "[ specify a message in the 'msg' argument on the
URL ]";
// create simple doc and write to a ByteArrayOutputStream
Document document = new Document();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PdfWriter.getInstance(document, baos);
document.open();
document.add(new Paragraph(msg));
document.close();
// write ByteArrayOutputStream to the ServletOutputStream
response.setContentType("application/pdf");
response.setContentLength(baos.size());
ServletOutputStream out = response.getOutputStream();
baos.writeTo(out);

Assunto: Re: [iText-questions] JSP problem
Hi Roberto,
It's hard to exactly control the output that's made from a JSP. For
example, if you have some white spaces in your code outside the <% %>
tags, the JSP will implicitely send them back to the client as well as
the output you have made through iText, this could lead into corrupted
PDF output because of leading / trailing white spaces or other content.
Why don't you use a servlet to perform this output?
Best Regards,
Christian
