I installed the following software in my machine successfully.
- Virtual Machine (VM).
 - Ubuntu 12.04 32bit.
 - Oracle 10g Express edition 32bit.
 - Lucee (lucee-4.5.1.000-pl0-linux-installer.run)
 - Contentbox
 
After above all installation I go http://localhost:8888/lucee/admin/server.cfm for check configuration all are working fine.
Next I go to this URL http://localhost:8888/contentbox/ for the configuration of contentbox with oracle database, when I go to create data source, there is no 'oracle database' in dropdown list of database 

(source: imgh.us)  
Can anyone help me at this point?
Is contentbox integration possible with oracle? 
                        
We have not fully certified ContentBox on Oracle at this point. However, I am glad to help you out and do that if you can provide feedback and debug it.
