RE: embedding fop0.20.5 working on jdk1.3.1-linux?
Thanks, Ganesh Is XML parsers xercesImpl-2.2.1.jar? I can not find other XML Parsers in my classpath and current fop0.20.5 directory. I tried running the Sample document on the command line on the linux machine? There is also java.lang.NoSuchMethodError: org.apache.batik.dom.AbstractAttr: method isReadonly()Z not found. I narrowed down the problem to the input image file from my xsl file. If I comment fo:blockfo:external-graphic src=file:nsf_logo.svg / /fo:block from my xsl file, it did generate PDF file. Otherwise, it will cause java.lang.NoSuchMethodError method: org.apache.batik.dom.AbstractAttr: isReadonly()Z not found. But I put svg image files, xml file, xsl file, pdf file and fop.sh in the same folder fop-0.20.5. There is no reason FOP can not find the image file. Could you explain the reason?

RE: embedding fop0.20.5 working on jdk1.3.1-linux?
I just change (fo:external-graphic src) to jpg file from svg file. Fop did work for me. Now I guess the reason why the same code works fine in jdk1.4.1 on windows XP not in jdk1.3.1 on linux. My Open BSD may not support graphical environment for SVG. Am I right? Any solution for it?

RE: embedding fop0.20.5 working on jdk1.3.1-linux?
One more thing:
After I run this servlet, I will get a java.lang.OutOfMemoryError when I try
to display another web page.
Here is my code about FOP:
public static final String XSLFILE = /hr/xsl/jobdesc.xsl;
protected Logger log = null;
protected void doGet(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException
{
...
if (log == null) {
log = new ConsoleLogger(ConsoleLogger.LEVEL_INFO);
MessageHandler.setScreenLogger(log);
}
try {
...
String fullPath = getServletContext().getRealPath( XSLFILE
);
File xslfile = new File(fullPath);
// create StreamSource for XSLT document
Source xslSource = new StreamSource( xslfile );
// create DOMSource for source XML document
Source xmlSource = new DOMSource( jobDocument );
renderBrowser(xmlSource, xslSource, response );
}
// catch XML parser exceptions
catch ( ParserConfigurationException pcException ) {
pcException.printStackTrace();
}
catch (ServletException ex) {
throw ex;
}
catch (Exception ex) {
throw new ServletException(ex);
}
}
private void renderBrowser( Source xmlSource, Source xslSource,
HttpServletResponse response ) throws ServletException
{
try {
//Construct driver
Driver driver = new Driver();
//Setup logger Renderer (output format)
driver.setLogger(log);
driver.setRenderer(Driver.RENDER_PDF);
//Setup output
ByteArrayOutputStream out = new
ByteArrayOutputStream();
driver.setOutputStream(out);
// create TransformerFactory to obtain a Transformer
TransformerFactory transformerFactory =
TransformerFactory.newInstance();
// create Transformer for performing XSL
transformation
Transformer transformer =
transformerFactory.newTransformer( xslSource );
//Resulting SAX events (the generated FO) must be
piped through to FOP
Result result = new
SAXResult(driver.getContentHandler());
// perform transformation and deliver content to
client
transformer.transform( xmlSource, result );
byte[] content = out.toByteArray();
response.setContentType(application/pdf);
response.setContentLength(content.length);
response.getOutputStream().write(content);
response.getOutputStream().flush();
}
// handle exception when transforming XML document
catch ( TransformerException transformerException ) {
transformerException.printStackTrace( System.err );
}
catch (Exception ex) {
throw new ServletException(ex);
}
}
I really need help to fix this problem.
Thanks

Try to find out if anything is logged in the Tomcat Logs. If not try to
set your own logger for FOP:
[1] http://xml.apache.org/fop/embedding.html#basic-logging
[2] http://xml.apache.org/fop/embedding.html#logging
If your Linux is running in a headless environment (no X subsystem) then
the following link may help:

Have you checked that you're using the right batik.jar (the one that comes with the FOP version you're using) and that no other batik.jar is somewhere in the classpath. You could enable classloading verbosity (-verbos:class) to find out where the classes are loaded from. Have you tried running the same document on the command line on the linux machine? AbstractElement.setUnspecifiedAttribute This method may (!) indicate that you have an unsupported attribute somewhere in your SVG code. I'm not sure. Try commenting out all SVG elements and see if that changes anything.

RE: embedding fop0.20.5 working on jdk1.3.1-linux?
Thank you so much, Jeremias. I narrow down the problem to the input image file from xsl file. If I add fo:blockfo:external-graphic src=file:nsf_logo.svg / /fo:block to my xsl file, it will cause java.lang.NoSuchMethodError. If I comment it out, it did generate PDF file. But I am wondering I put image files, xml file, xsl file, pdf file and fop.sh in the same folder fop-0.20.5. There is no reason FOP can not find the image file. Could you explain the reason?

When you call java -? on the command line you see all its available options. When -verbose:class is set, you should receive lots of lines, one for each loaded class with information where the class was loaded from. This can help identify classloading problems (duplicate jars in the classpath, for example). But this step is now mostly superfluous because you saw that the same result happens on the command line. As the next step I suggest commenting out portions of your input document or stylesheet to further narrow down the problem point. That's a tedious job but it is a technique I often use with success.
