How to: java code

Question

I was going through different documentations for using Java with BI Publisher.
For example:
Example 7-4 Sample Code for Retrieving a List of Field Names
import java.util.Enumeration;
import oracle.xdo.template.FormProcessor;
+.+
+.+
+.+
FormProcessor fProcessor = new FormProcessor();
fProcessor.setTemplate(filePath);        // Input File (PDF) name
Enumeration enum = fProcessor.getFieldNames();
while(enum.hasMoreElements())
Question:
How do I use Java API/Code with Oracle EBS (11.5.10)? I mean, if I write a Java code to do some complex task, how will I reference it in BI Publisher(stand alone)? Is the Java API's useful only for OAF/r12?
Thanks in adavnce.

Java may be easier to get back to source, but in reality, there is no "safe way" to release code, so you should never put anything in it that you don't want viewed. That does not mean that there isn't ways to make it harder to view the code. Obfuscation is one thing that can be done, but you can be guaranteed that anything you do to make the code "unreadable" can be undone. I used to delight in going over code, decompile it, or, at times, just fishing through the machine code bytes to see what was there.
I am one that subscribes to the idea that there is no such thing as security, anyone that really wants to break in or read a product or site is going to do it. It is a game we play as programmers that goes like this: how difficult can I make it so most people leave my site alone or do not steal my code? Once the idea comes out of your head, it's fair game for anyone that really wants to take the time and effort to steal it.
If you do not want people to have your code, do as already suggested: do not release it, make a webservice and have it hoasted on a site. Make multiple tiers of objects with your most sensitive being called with arguments from previous layers to allow them to do their jobs without the end user ever seeing it's there, where it's located, or really what it does--hide it, don't let the user see it.
