Custom XSQL Serializers Error

Question

Hi,
I have wrote the following custom XSQL Serializer to render the PDF.
import org.w3c.dom.Document;
import org.apache.log.Hierarchy;
import org.apache.fop.messaging.MessageHandler;
import oracle.xml.xsql.XSQLPageRequest;
import oracle.xml.xsql.XSQLDocumentSerializer;
import org.apache.fop.apps.Driver;
import org.apache.log.output.NullOutputLogTarget;
//Avalon
import org.apache.avalon.framework.ExceptionUtil;
import org.apache.avalon.framework.logger.ConsoleLogger;
import org.apache.avalon.framework.logger.Logger;
/**Customized serialize for FOP
* Tested with the FOP 0.20.3RC release from 19-Jan-2002
public class renderPDF implements XSQLDocumentSerializer {
private static final String PDFMIME = "application/pdf";
public void serialize(Document doc, XSQLPageRequest env) throws Throwable {
try {
// First make sure we can load the driver
Driver FOPDriver = new Driver();
// Tell FOP not to spit out any messages by default.
// You can modify this code to create your own FOP Serializer
// that logs the output to one of many different logger targets
// using the Apache LogKit API
//Setup logger
Logger logger = new ConsoleLogger(ConsoleLogger.LEVEL_DISABLED);
FOPDriver.setLogger(logger);
// Some of FOP's messages appear to still use MessageHandler.
MessageHandler.setOutputMethod(MessageHandler.NONE);
// Then set the content type before getting the reader/
env.setContentType(PDFMIME);
FOPDriver.setOutputStream(env.getOutputStream());
FOPDriver.setRenderer(FOPDriver.RENDER_PDF);
FOPDriver.render(doc);
catch (Exception e) {
// Cannot write PDF output for the error anyway.
// So maybe this stack trace will be useful info
e.printStackTrace(System.err);
When I run this code from the Jdeveloper using the embeded server, everything works fine, but when I deploy the code to Tomcat I am getting the following error I am using the FOP 20_03 Jar files and Jdeveloper 9.03
Oracle XDK Java 9.0.3.0.0 ProductionXSQL-023: Class servlet.renderPDF is not an XSQL Serializer
I have the following statement in XSQL page to call the custom XSQL serializer
<?xml-stylesheet type="text/xsl" href="xsl/invoice_pdf.xsl" serializer="java:servlet.renderPDF" ?>
Any comments or solution will be really appericated:
Thanks in advance:

Answer 1

I'm trying to write a servlet in jDeveloper to take the XML document produced by XSQLRequest and an XSL (FO) file and produce a PDF response. So far I am unable to get jDeveloper to be able to find the Apache FOP jar files.
How did you get jDeveloper to be able to find the Apache FOP jar files?
Thanks in advance,
Tom.
