Hi
I'm new to java, but I've written a small java service which uses
the FOP library. Every time FOP generates a PDF, there are a lot of
warnings spat out on the console. Is there any way I can disable the
render warnings and then filter any serious messages to a log file?
In FOP 0.95, you cannot really 'disable' the warnings, unless by
changing the log-level.
What is definitely possible, is to create your own logger subclass,
and add the desired behavior in its warn() or error() handler.
Note:
* as FOP uses Jakarta Commons Logging as an abstraction layer, this
all depends greatly on the actual log implementation that is used
(Log4J, standard JDK logging...)
* FOP uses static loggers, so if your application possible runs
multithreaded, you may need to use a ThreadLocal to sort out which
message comes from which thread (Suggestion: search the fop-users
archive for "Log4J" and "ThreadLocal", as I am quite sure a similar
question was answered in the past couple of weeks)

If you can use FOP Trunk (stable enough for a lot of our users), you
get a whole new range of possibilities for handling 'events'.
See: http://xmlgraphics.apache.org/fop/trunk/events.html
HTH!
