If you are using the latest CVS it should work...
However you might have to call driver.setLogger()
to give FOP a LogKit Logger...
In my program I have something like this...
Driver driver;
ByteArrayOutputStream out = new ByteArrayOutputStream();
driver = new Driver();
// FOP uses Avalon LogKit for Logging, so we need to set it up.
org.apache.log.Hierarchy hierarchy =
org.apache.log.Hierarchy.getDefaultHierarchy();
org.apache.log.format.PatternFormatter formatter = new
org.apache.log.format.PatternFormatter("[%{priority}]:
%{message}\n%{throwable}");
org.apache.log.LogTarget target = new
org.apache.log.output.io.StreamTarget(System.out, formatter);
hierarchy.setDefaultLogTarget(target);
org.apache.log.Logger log = hierarchy.getLoggerFor("fop");
log.setPriority(org.apache.log.Priority.ERROR);
driver.setLogger(log);
driver.setRenderer(Driver.RENDER_PDF);
driver.setOutputStream(out);
ContentHandler cnth = driver.getContentHandler();
// send SAX events on cnth.
and it works with the yesterday's CVS...
Keiron, Could you take a look at the things you did for the logger
in driver, it look wierd to me as the _treeBuilder 's logger
is only set if a call to setLogger is done, otherwise I get a
NullPointerException
If you want I can take a look... just say so.
