Although it's written in python, it should be easy to port to other languages such as Perl.
Apache httpd.conf :
LoadModule python_module modules/mod_python.so
...
Python script:

<process-type id="INST1" module-id="OC4J" status="...
Or, you can add it through the Oracle em console. Go to the OC4J container, click "Administration" tab, then "Server Properties". Add "-userThreads" to "Start-parameters: OC4J Options".
Debu Panda has written a good article on using quartz in the Oracle environment: Using Quartz Enterprise Scheduler in J2EE

<?xml version = '1.0' encoding = 'windows-1252...

<?xml version = '1.0' encoding = 'windows-1252...

Full information is available from the Oracle document titled "Oracle Containers for J2EE Enterprise JavaBeans Developer's Guide 10g (10.1.3.1.0)". Look at Appendix A.
