Hi Theresa,
I believe there are multi-threading gotchas when embedding FOP and her
dependencies; see
http://xmlgraphics.apache.org/fop/0.95/embedding.html#multithreading,
There are certainly many multi-threaded production systems that have
successfully embed FOP and it would be nice to know some of the issues
that were faced whilst they were being developed. it would be very
useful to have a page on the website, or perhaps on the wiki dedicated
to this subject, included some war stories and solutions devised.
We didn't notice any big problems in our integration. Just read the
Javadoc to see which classes are thread-safe and which aren't.
You can create a singleton FopFactory, but you have to create new
FOUserAgent and Fop objects for each new transformation.
You can look here for an example:

I am looking into redoing my FOP integration and maybe adding it into some
form of MQ service,
So many applications can request fop functionality and then have their
response sent on the MQQueue,
How Threadsafe is the Fop engine? Or is the current newFopInstance from a
singleton factory instance totally threadsafe?
Are there any catcha’s I need to be aware of?
Kindest regards
