I am using fop 0.9. I am not sure if in fop 0.9 i can get log messages while the pdf is being rendered, as we get in fop 0.2. In fop 0.2 i use to set driver.setLogger(log), to get the log messages. But how do i do it in fop0.9.
Please suggest.
Once i have set up say log4j and used commong-logging, but how would i give this logger to fop . Like in fop 0.5 we use to have the following code with driver.setLogger(loggger);

Driver driver = new Driver(foSource, l_baOutStream);
Below are the log messages which i used to get in fop 0.2
[INFO]: Using org.apache.xerces.parsers.SAXParser as SAX2 Parser
[INFO]: building formatting object tree
[INFO]: setting up fonts
[INFO]: [1]

[DEBUG]: Memory use is indicative; no GC was performed
[DEBUG]: These figures should not be used comparatively

But with fop 0.9, below is how pdf is being rendered. In this code how do i set logger so that fop messages are redirected to log4j

// configure foUserAgent as desired
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();

// Construct fop with desired output format
Fop fop =fopFactory.newFop(MimeConstants.MIME_PDF,foUserAgent,l_baOutStream);

// Setup JAXP using identity transformer
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer();

// 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(foSource, res);

Best Regards,
