Unable to create Java Fact in JDeveloper

Question

I'm unable to create a Java Facts for all of the classes I need to in a JDeveloper project. When I create the java fact I can see that the classpath shows my projects .../target/classes/ directory. In the classes panel I can see all my classes. However when I select classes to add as facts I do not get all the classes I selected. I do not get an error either. I have attempted to analyze the differences between classes that successfully get added as facts and those that simply do not get added as facts when selected but I can't find a method to the madness. I have done this successfully with simple "hello world" type example but when trying to expand to a larger corporate code base the wheels fall off.
I'm using JDeveloper 11.1.1.4, Windows 7, JDK 1.6 update 21.

I think this has to do with not having facts for all the dependent java classes in the dictionary already. I need to better understand the proper way to build dictionaries in a modular way. I don't think the "User's Guide for Oracle Business Rules" is detailed enough.
I'll try to explain.
Project A - has some base classes, interfaces and abstract classes
Project B - has some base classes, interfaces and abstract classes
Project C - uses project A (implements interfaces, extends classes etc.)
Project D - uses project D (implements interfaces, extends classes etc.)
Project E - uses projects A, B, C & D
When I build a dictionary for Project A it appears OK, same with Project B
When I build a dictionary for project C I like the dictionary from Project A.
When I build a dictionary for project D I like the dictionary from Project B.
When I build a dictionary for project E it appears I have to link dictionaries for projects A, B, C & D but I end up with the original problem I posted on.
I just took a class X from Project E with dependencies on projects A, B, C & D (by dependencies I mean used objects in any way, inheritance, method arguments, properties etc.). I could not create a fact for class X using the above described method.
I manually did a parent child graph of all the dependencies of class X. If create facts for all the classes at the lowest level (these classes are only dependent up on classes in rt.jar) first all the facts are created fine. If I then create facts for all the classes the next level up the graph, they are all fine. I can climb my way up the graph adding facts for the classes just fine all the way to class X. In this scenario I'm able to create a fact for class X.
This exercise is extremely slow and not maintainable. What I really need is a better understanding of how to modularize the dictionaries, ideally to match the code base and how to keep these dictionaries in sync with changes to the code base. Can anybody point me to some documentation on this or recommend a book?
