New FOP Code Don't Work

[Jim Urban <ji...@netsteps.net>]

Recently someone suggested using SAX events to run XML through XSLT then FOP
and to send the PDF back to the browser from a servlet.  I tried implmenting
this (see code below) but all I don't get any output back.  I even routed
the output to a file, and the file was empty.  My old code worked great, but
I was told I was wasting memory.  Can someone tell me why this code does not
work?

Thanks,

			// -------
			// Create SAXResult based on FOP Driver content
handler
			// which will accept SAX events and build FOP tree
			// -------
			Result saxResult = new
SAXResult(driver.getContentHandler());

			// Use the Transformer to transform an XML Source
and
			// send the output to a Result object. Implicitely
it will
			// create the FOP tree by firing SAX events.
			pdfTransformer.transform(iInputSource, saxResult);

			// The user is already viewing the PDF!
			out.flush();
			out.close();

		catch (TransformerException e1)

e1.toString());
