Thank you for sampling the Java Tool Kit online demonstration by Dan Oross Consulting. Attached is a dynamically generated ZIP file containing the original HTML file you uploaded and the PDF document converted on-the-fly.

Take notice of the embedded images and HTML within this email, and the directory structure within your ZIP file!

Java Tool Kit

Overview

The purpose of this page is to demonstrate the power of all four Java Tool Kit components in one simple form. Unfortunately, one simple form hardly exhibits the hundreds of features that these objects possess.

Be sure to view the online Java Tool Kit API specification for all of the methods and options available. Or feel free to email Dan Oross Consulting with any questions or comments.

• View the HTML-to-PDF conversion guide and known issues

• View the DanOross.com homepage converted to PDF with the Java Tool Kit

Instructions

For the purposes of this demonstration, you must enter your email address and select a well-formed HTML file to upload to the Dan Oross Consulting server. The Java Tool Kit will process the file UPLOAD, convert the HTML to PDF, ZIP the file and EMAIL it back in a single stream, on-the-fly, without writing any files to disk. Optionally, you may also enter an absolute base URL, like http://www.DanOross.com, to provide relative link support for stylesheets and images.

Your email address will ONLY be used to send the resulting PDF document. It will not be stored, sold or used... EVER!

The document size, margins, orientation, image and text split settings, forced page breaks, and virtual browser render width cannot be adjusted for the demonstation. The request timeout is 30 seconds and the HTML parser timeout is 15 seconds, to prevent oversized file upload and input stream processing.
