APEX

Okay I'm totally confused on how to configure the FOP thing and believe me I've really tried.
===========
Here is what I've got:
1) Linux 4.0 Server with 10gAS 10.1.3 installed on it.
2) Directory Structure for my oc4j and this was done by the OUI= /u01/app/oracle/MWRDTSTdb/iAS101/j2ee/home/oc4j.jar
3) I have web site to monitor my oc4j http://metrotst:7779/em I can log into here and stop and start the application servers.
==================
Anyway so what I did was put the apex_fop_render.jsp under /u01/app/oracle/MWRDTSTdb/iAS101/j2ee/home/default-web-app.
--
I then created a directory /u01/app/oracle/MWRDTSTdb/iAS101/j2ee/fop-0.20.5 and unzipped all of the Apache FOP Version 0.20.5 libraries.
--
I then put the FOP library entries into the /u01/app/oracle/MWRDTSTdb/iAS101/j2ee/home/config/applications.xml file as I've seen stated on OTN on a few post.
---
Now here is where I'm really confused because for me in my environment to restart the OC4J I enter # opmnctl stopall and then #opmctl startall of course that is if I can afford to bounce Apache as well.

But I'm really getting confused about the port 8888 thing because my web server is running on 7779. Maybe there is some document that I'm missing or I'm just completely not getting this thing at all.

==================================
Any help would be greatly appreciated.
