Hi. the following is my code:
//DOM
import org.w3c.dom.*;
import org.apache.xerces.parsers.*;
//Java
import java.io.*;
import java.io.File;
import java.lang.String;
import java.net.URL;
import org.apache.fop.apps.*;
import org.apache.fop.messaging.*;
import org.xml.sax.*;
public class XMLPDF
{
public static void main(String[] args)
{
File xmlf = new File(c:/jdk1.3.1/xslfoRef.xml);
File xslf = new File(c:/jdk1.3.1/xml2pdf.xsl);
File writefile = new File(shu.pdf);
Driver driver = new Driver();
driver.setRenderer(Driver.RENDER_PDF);
InputHandler inputHandler = new XSLTInputHandler(xmlf, xslf);
XMLReader parser = inputHandler.getParser();
InputSource inputSource = inputHandler.getInputSource();
driver.setOutputStream(new FileOutputStream(shu.pdf));
driver.render(parser, inputSource);
//outfile.close();
}
}
I got the following error message:
unreported exception org.apache.fop.apps.FOPException: must be
caught or declared to be thrown
XMLReader parser = inputHandler.getParser();
^
it has the same error messgae for driver.setOUtputStream and
driver.render.
I have no idea what's wrong, plese kindly help.

Put all this code in try block.
Like this
try{
File xmlf = new File(c:/jdk1.3.1/xslfoRef.xml);
File xslf = new File(c:/jdk1.3.1/xml2pdf.xsl);
File writefile = new File(shu.pdf);
Driver driver = new Driver();
driver.setRenderer(Driver.RENDER_PDF);
InputHandler inputHandler = new XSLTInputHandler(xmlf, xslf);
XMLReader parser = inputHandler.getParser();
InputSource inputSource = inputHandler.getInputSource();
driver.setOutputStream(new FileOutputStream(shu.pdf));
driver.render(parser, inputSource);
//outfile.close();
} catch (Exception ex) {
}

Re: FOP exception
While Ivan's reply is correct, it is really a bit quick and dirty.
For less experienced Java programmers a slightly fuller explanations is:
Any method in Java can choose to throw an exception if something goes
wrong. The caller of that function must be prepared to handle any
exceptions that may be thrown and then do whatever they think is most
appropriate. What Ivan's sample code does is catch any exception (
remember all exceptions extend the class java.lang.Exception) and ignore
the error. 'Swallowing' exceptions in his way is generally a bad practice
as when something goes wrong, you never find out about it. The minimum you
should do is either: rethrow the exception to your caller or print a stack
trace.
Very often you will want to handle different types of exceptions in a
special way and so should catch org.apache.fop.apps.FOPException for
example.
