2 TopLink Java Object from Table to be used in single selectOneChoice

Question

Hello everyone, can I ask for help on how to solve my problem....
Here's my scenario, I have 2 tables namely tblCollege and tblCourse, they are related through tblCourse.CollegeCode = tblCollege.Code.
I use the jdeveloper wizard using TopLink -> Java Object from Table to add these table to my project. I created an EJB Data Control so that I can use them to my Userinterface using ADF Faces.
What I really want to do is that I need to have selectOneChoice component displaying:
tblCollege.Name + tblCourse.Name, and it should have a value of tblCollege.Code + tblCourse.Code,
so for example in my
tblCollege:
Code---------Name
1---------------Science
2---------------Music
tblCourse
Code-------Name-----------CollegeCode
1-------------Biology----------1
2-------------Computer-------1
3-------------Guitar------------2
what I want in my selectOneChoice is like this:
value----------display
1-1--------------Science-Biology
1-2--------------Science-Computer
2-3--------------Music-Guitar
I'm a little stuck on how I'm going to that. Thanks.

Bawasi,
I see a couple of angles of attack, but this really depends on the technologies involved. If you are using ADF Bindings in combination with ADF Faces then you need to shape the data at the entity level. If ADF Bindings are no the in equation, you can take a less aggressive approach and shape the data in a managed bean. What is not clear to me is the end-to-end use-case. I see the read-only (i.e. how to get data to the drop box), but I am
not certain what attribute on an entity you are attempting to set. Are you trying to set the course for the current user or for a master schedule? Finally, notice that the final shape of your data set shows a unique combinations, you could increase the performance of your use-case and ease of development simply by denormalizing your schema.
