Hi,
I get a planned Exception while invoking transformer.transform.
Unfortunately I can not catch this Exception. This is the code:
try {
// construct fop with desired output format
Fop fop = fopFactory.newFop(type, foUserAgent, out);
// setup XSLT
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new
StreamSource(xsltfile));
// Set the value of a in the stylesheet
transformer.setParameter("versionParam", "2.0");
// setup input for XSLT transformation
Source src = new DOMSource(dom);
// resulting SAX events (the generated FO) must be piped
through to
FOP
Result res = new SAXResult(fop.getDefaultHandler());
// start XSLT transformation and FOP processing
transformer.transform(src, res);
} catch (Exception e) {
System.err.println("ERROR: " + e.getMessage());
} finally {
out.close();
}
Altough transformer.transform() has an Exception, I never get the System.err
message. Instead I only get the ERROR-message from log4j (see below). I need
to catch the Exception in order to react with my program. Am I missing
something here?
Thanks,
Frank
