Java: How can I generate a PDF file from a JSP JSP page?

Question

I need to create a PDF file from a JSP JSP page. I searched the network, but I did not find examples of how to do this. I need to convert the whole page, or maybe just the diagrams that I have on this page.

PS I also use IceFaces.

Answer 1

The easiest way is to capture the HTML using Filter and convert it to PDF using the appropriate API, then return the application/pdf data from Filter . It may be possible to support partial submission of IceFaces files to support a subset of the component's output, but you may have to examine the details of IceFaces HTTP requests to figure out how to use this.

Answer 2

As far as I know, this is not possible. You can use Jasper Reports to create a pdf file on the server side. Or you can use PrintPDF , which is a firefox plugin to create one from a web browser.

Answer 3

You may need the following:

• Capturing (X) the HTML output of your page. This can be done using the following code in your servlet:

   InputStream is = new URL("http://localhost/foo/page.jsf").openStream(); 

• Convert captured content to pdf. See the rendering of the Flying Saucer (and additionally this stream )

• "Submit" generated PDF file. That is, just write (print) your pdf file to response.getOutputStream() and set the Content-Type header to response.setContentType("application/pdf")
