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

Subject: Re: embedding fop0.20.5 working on jdk1.3.1-linux?
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:
http://xml.apache.org/fop/graphics.html#batik
Good luck!
