I have Apex 4.1 up and running great on an 11gr1 database.
The Apex 4.1 listener is running on a Fusion Middleware 11g
I can't find any straight forward info on if it is possible to install the
fop.war file directly into Fusion Middleware control or if I still have to go
and install OC4J and install the fop.war file there.
I saw where the weblogic server is a replacement for oc4j but I would have thought
there would have been at least a guide or something to install fop.war to fusion's weblogic server.
If it is there I can't find it.

And there are also some changes to the FOP JSP that would have to be made. The following thread contains some more details:
