How can I get controller .java files

Question

I have craeted OA extension pages in which I have created Entiy object, module and view objects
in JDeveloper for 12.1.1 in windows and it working fine.
Now I want to extend one of the page of payable module (payable vision operation (USA))
and the page name is SuppSummaryPG.xml .
The problem is that how can I open or import SuppSummaryPG.xml in my jdeveloper ID
and all the related files which belongs to SuppSummaryPG.xml , example raleated VO, entity objects
module file and controller servlet.
I move all the files from
apps server to jdeveloper directory , i did the same thing which is running
and working fine but the problem is with all of ViewObject and aplication module
I am not able to open these in Jdeveloper , because when I try to open these files
it gives me error that you dont have .java files , and it opens view objects and applicatino
moudel files in read only mode
the page is a standrad java moudle page
suppSummaryPG is a standard page and it is in
payable moudle herachy is
oracle/apps/pos/supplier/....suppSummaryPG
what should I do

Answer 1

You can use decompiler to read java code. Oracle doesn't have any policy to prevent you from reading the class files.
However you cannot change the java code and replace the standard files.
Source Code:
Oracle sells the just the software. So they are not obligated to provide source code.
The reason why they provided soruce code for forms and reports is that there is no robust personalzation and extention concepts available for them.
As per Oracle Support services, you dont need OAF code for extension and personalization.
