public class FopPrintServlet
extends FopServlet

Example servlet to generate a fop printout from a servlet. Printing goes to the default printer on host where the servlet executes. Servlet param is:

• fo: the path to a XSL-FO file to render

or

• xml: the path to an XML file to render
• xslt: the path to an XSLT file that can transform the above XML to XSL-FO

Example URL: http://servername/fop/servlet/FopPrintServlet?fo=readme.fo
Example URL: http://servername/fop/servlet/FopPrintServlet?xml=data.xml
Note: This servlet is derived from FopServlet. Most methods are inherited from the superclass. Only the differences to the base class are necessary.

Method Detail

render

protected void render(javax.xml.transform.Source src,
                      javax.xml.transform.Transformer transformer,
                      javax.servlet.http.HttpServletResponse response)
               throws FOPException,
                      javax.xml.transform.TransformerException,
                      java.io.IOException

Renders an input file (XML or XSL-FO) into a PDF file. It uses the JAXP transformer given to optionally transform the input document to XSL-FO. The transformer may be an identity transformer in which case the input must already be XSL-FO. The PDF is written to a byte array that is returned as the method's result.

Overrides:

render in class FopServlet

Parameters:

src - Input XML or XSL-FO

transformer - Transformer to use for optional transformation

response - HTTP response object

Throws:

FOPException - If an error occurs during the rendering of the XSL-FO

javax.xml.transform.TransformerException - If an error occurs during XSL transformation

java.io.IOException - In case of an I/O problem
