FOP and XSQL

Question

Hi,
i'm trying to use fop with xsql.
When i execute the sample emptable.xsql i receive the following error message :
XSQL-017: Unexpected Error Occurred
java.lang.NoClassDefFoundError: org/xml/sax/helpers/DefaultHandler
at oracle.xml.xsql.serializers.XSQLFOPSerializer.serialize(XSQLFOPSerializer.java:50)
at oracle.xml.xsql.XSQLPageProcessor.process(XSQLPageProcessor.java, Compiled Code)
at oracle.xml.xsql.XSQLServlet.doGet(XSQLServlet.java:60)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:499)

at org.apache.jserv.JServConnection.run(JServConnection.java:290)
at java.lang.Thread.run(Thread.java:479)
i work with the 0.18.1 version of fop, the db is the 9i version and the xsqlserializer is take from the release candidate 1 of jdeveloper. I try with all version of fop, but i don't have success.
Which is the right configuration of all components to work correctly with fop ?
Thanks,
Stefano.

I'm using the XSQL servlet 9.2.0.2.0 and FOP 0.20.3. But you have to write your own FOPSerializer. I foun this source here in the forum:
import org.w3c.dom.Document;
import java.io.PrintWriter;
import oracle.xml.xsql.*;
import org.apache.fop.apps.*;
import org.apache.log.*;
import org.apache.log.format.*;
import org.apache.log.output.io.*;
import org.apache.avalon.*;
import java.io.*;
public class XSQLFOP203Serializer implements XSQLDocumentSerializer {
private static final String PDFMIME = "application/pdf";
private static final String CONFPATH = "/usr/local/fop/conf/userconfig.xml";
public void serialize(Document doc, XSQLPageRequest env) throws Throwable {
try {
// Open user config file
File userConfigFile = new File(CONFPATH);
Options options = new Options(userConfigFile);
// First make sure we can load the driver
Driver FOPDriver = new Driver();
// Setup logging
Hierarchy hierarchy = Hierarchy.getDefaultHierarchy();
PatternFormatter formatter = new PatternFormatter("[%{priority}]: %{message}\n%{throwable}" );
LogTarget target = null;
target = new StreamTarget(System.out, formatter);
hierarchy.setDefaultLogTarget(target);
Logger log = hierarchy.getLoggerFor("fop");
log.setPriority(Priority.INFO);
FOPDriver.setLogger(log);
// Then set the content type before getting the reader/
env.setContentType(PDFMIME);
FOPDriver.setRenderer(FOPDriver.RENDER_PDF);
FOPDriver.setOutputStream(env.getOutputStream());
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);
Hope this helps.
