Right, I have got it working!
Thanks for your help Jeremias - you were right about input.run() running in
my test (which was the old way - which was causing the error!).. the key
was to use the ExampleObj2PDF logic in the servlet...
Maybe the example can be updated with my version? I have not compiled this,
but I know it works...
Here is :
public void execute(HttpServletRequest request, HttpServletResponse
response)
throws IOException, ServletException {
ByteArrayOutputStream out = null;
try {
ProjectTeam projectTeam = new ProjectTeam();
projectTeam.setProjectName("test");
Driver driver = new Driver();
Logger logger = new ConsoleLogger(ConsoleLogger.LEVEL_INFO);
driver.setLogger(logger);
MessageHandler.setScreenLogger(logger);
driver.setRenderer(Driver.RENDER_PDF);
out = new ByteArrayOutputStream();
driver.setOutputStream(out);
File xslFile = new
File("./../webapps/myappname/WEB-INF/classes/mypkgname/fop",
"projectteam2fo.xsl");
//Setup XSLT
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new
StreamSource(xslFile));
//Setup input for XSLT transformation
Source src = incident.getSource();
//Resulting SAX events (the generated FO) must be piped through
to FOP
Result res = new SAXResult(driver.getContentHandler());
//Start XSLT transformation and FOP processing
transformer.transform(src, res);
byte[] content = out.toByteArray();
response.setContentType("application/pdf");
response.setContentLength(content.length);
response.getOutputStream().write(content);
response.getOutputStream().flush();
} catch (Exception e) {
throw new ServletException(e);
} finally {
if (out!=null) {
out.close();
}
}
}
Regards

Does the problem persist if you serialize the SAX events generated by
the Incident with an identity transformer to a file and run the XSL
transformation stand-alone from the command-line?
I don't think it's a problem but did you realize that you have two FOP
processing runs in your testGeneratePDF() method, the first started by
Transformer.transform() and the other by input.run()? Since I can't do
anything with the line numbers in the stack trace, this is something you
have to do.
