how starting FOP without XML-File
Hallo
I generate my
PDF-File in a servlet:
File
xmlFile = new
File("c:/temp/test.xml"); File
xslFile = new
File("c:/temp/test.xsl");
InputHandler inputHandler = new XSLTInputHandler(xmlFile,
xslFile);
org.xml.sax.XMLReader parser =
inputHandler.getParser();
driver.buildFOTree(parser,
inputHandler.getInputSource());
driver.format();
driver.setOutputStream(out);
driver.render();
In the above example
the xml input source is a file. But I would rather passthe input
source xml file (text.xml) in the memory. It's possible and howcan I do
this?
Thanks
Marc

RE: how starting FOP without XML-File
Thanks
for the answer!
But
with your solution, I can't pass the fop xsl file. This file is on the
filesystem. Could you help me?
Thanks

String object and write the PDF outputback to the

ByteArrayOutputStream out = new
ByteArrayOutputStream();
response.setContentType("application/pdf");

driver.setRenderer(Driver.RENDER_PDF);
driver.run(); byte[] content
= out.toByteArray();
response.setContentLength(content.length);
response.getOutputStream().write(content);
response.getOutputStream().flush();
response.flushBuffer(); }Jim

RE: how starting FOP without XML-File
If I understand you correctly, in your servlet you wish to apply an xsl
style sheet (from a file) to an xml string in memory to generate a FO xml
string in memory to run through FOP to generate a PDF in memory which you
want to return to the browser. If that is the case, here are the pieces for
your servlet...
These are class variables...
TransformerFactory tFactory= null;
Transformertransformer = null;
Place this code in your init method to save reading and parsing the xsl file
each time your servlet is called...
tFactory = TransformerFactory.newInstance();
String xslFile = myfile.xsl;
File theFile = new File(xslFile);
Source xslSource = new StreamSource(theFile);
transformer = tFactory.newTransformer(xslSource);
This code goes in your doGet / doPost method and replaces the code from the
previous email...
try
{
String xmlString = ... function to generate your xml String.
Writer out = new StringWriter();
Source xmlSource = new StreamSource(new StringReader(xmlString));
transformer.transform(xmlSource, new StreamResult(out));
out.close();
String fopstring = out.toString();
InputSource foSource = InputSource(new StringReader(fopstring));
ByteArrayOutputStream out = new ByteArrayOutputStream();
response.setContentType(application/pdf);
Driver driver = new Driver(foSource, out);
driver.setRenderer(Driver.RENDER_PDF);
driver.run();
byte[] content = out.toByteArray();
response.setContentLength(content.length);
response.getOutputStream().write(content);
response.getOutputStream().flush();
}
I hope this helps. I wish this example was part of the examples provided
with FOP. Maybe a FOP developer (I'm just a user) can add an example like
this to the FOP package.
