Help with Tapestry Page and iText
Hello,
Happy new year to all!! (Its new year here in India)..
Okay, i need a small help! I want to generate a PDF file, based on the
generated page in Tapestry.. I've plans of using iText to generate PDF. Can
any one help me? How to get it done!!
PS: On cliking Download PDF link, the PDF should be generated on the fly,

What would do the HTML to PDF conversion in this case?
There's one project, Flying Saucer (https://xhtmlrenderer.dev.java.net/),
that renders HTML to various formats, including to the screen (as a Swing
component) and PDF. It uses iText internally. This article shows how you
do it:

I guess this could be implemented as a mixin.

Shouldn't be too hard.
Do this in your page class:
Object afterRender(MarkupWriter writer) {
Document doc = writer.getDocument();
ITextDocument itextDoc = convertT5DocToItext(doc);
return new ITextStreamResponse(itextDoc);
}
I think you can also gain access to all generated markup from the
MarkupWriter (writer.toString()), and just pass the generated HTML on to
your PDF writer.
One example technique for making a PDF version of your pages is to subclass
your page and only include the afterRender method above. I'm sure there are
other (more elegant) ways to do this than the example I made here!
