## Class FopPrintServlet

- java.lang.Object
- - javax.servlet.GenericServlet
  - - javax.servlet.http.HttpServlet
    - - org.apache.fop.servlet.FopServlet
      - - org.apache.fop.servlet.FopPrintServlet

- All Implemented Interfaces:
    java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

      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&xsl=format.xsl
  Note: This servlet is derived from FopServlet. Most methods are inherited from the superclass. Only the differences to the base class are necessary.

          protected void render(javax.xml.transform.Source src,
                                javax.xml.transform.Transformer transformer,

                         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
