Now lets do something that's harder to do without the servlet utilities - generate a PDF page. JBuilder3 has no wizards to help with this one... but the changes to the previous code are minimal -> see the code

When you run the hello2 servlet and view it in your browser, what you'll get should be something like this.

Now here's what we did:

• Copied the source file and renamed the class to hello2
• Removed the HtmlPage object and several method calls
• Line 13 - identified the output format as being the MIME type of a PDF document
• Line 14 - constructed an instance of PdfPage using the servlet response as the destination stream
• Line 15 - preset the font type and size (in points - one point being 1/72 inch)
• Line 16 - output a string
• Line 17 - switch to a different font (in PDF, effects such as bolding use different fonts)
• Line 18 - output the string representation of the current date / time
• Line 19 - close the page and write the PDF data

The examples assume that you are working with server-side Java, but notice that you can easily output the PDF to a stream or a file. Consequently, you can use PdfPage in an application instead of a servlet.
