Solution 1:

Your MIME type is incorrect for PDF. It should be application/pdf.

Change

response.setContentType("text/pdf");

to

response.setContentType("application/pdf");

See https://www.rfc-editor.org/rfc/rfc3778 for the RFC for the PDF MIME type.

Edit: Totally overlooked the "Save as .pdf" question. You'll also need to add something like:

response.setHeader("content-disposition", "attachment; filename=yourFileName.pdf");

to tell the browser what the default file name should be.
