An example of View Object Extension in conjunction with Controller class extension

This is a real life implementation example of OA Framework Extension on Release12.
In this extension, you will see how to

   1. Extend a View Object to add a new Column
   2. How to extend a controller class
   3. How to apply substitution of View Object
   4. How to export personalization and deploy the same

Given that this was a real life solution implemented for a client of mine, I am unable to make the business requirement a public knowledge. For the very same principles, I am not detailing the source code for the controller extension.


But yet this document will give you a good idea of how extension of BC4J, extension of Controller and Personalizations work in tandem. This document also gives you steps involved for development & deployment, with screenshots where applicable.

Hello Anil-

I dont know how to post here...it keeps asking the new security image letters every time.. :(

I need more info on
1. Oracle EBS architecture
2. OM - Processing constraints
( how its implemeted using APIs and how they are ported from instance to instance)
3. OM Module as a Functional Consultant (not as a O2C user)

Pls, lemme know if my questions are not clear.

thx,
ch itra
(finally, firefox dint let me...but IE did show a message that the name i used has been already registered...so much for firefox, huh?)

Hi Chitra

I always use firefox, but never saw this issue.
Perhaps you should register yourself. The captcha image is not presented to registered users.

Please elaborate your OM Requirements. A friend of mine has proposed to write up on Order Management.

Th anks,
Anil Passi

oh, oops, i have juz registered ... (it let me post only once with the same user name.

My questions are basically similar to your "What happens when you login to Apps" article, except in OM module. In the view of functional consultant (not as a end-user), if you could throw some insights on the flow of processes invloved, it would be great.
I'm not asking for "What-to-do" steps as in how-to-book-ord er, how-to-pick-rel ease; instead "What happens in apps, what tables get affected, which APIs gets called" ..that sort of things...To help me troubleshoot any problem scenarios.

Sin ce I have limited knowledge on PL/SQL, sometimes it gets hard to understand the technical perspecive of things. But I am determined to give it a try.

Hope I'm not asking too much.

Thx agn-

Hi Ved,

Both the 9i Client and 10g Client contain the Workflow builder by default.

I think these can be downloaded from otn.

Good luck,
Anil Passi

hi
Hi All,

The client decided to go for R12 in the middle of implementation. We downloaded jDev patch p6197418_R12_Ge neric. We could make test_fwktutoria l.jsp work. Next we copied icx,ap,pa *.xml and *.class from Unix to desktop. Also exported required *PG.xml from mds.

Now we want to create a new project in jDeveloper. We did following

New -> Workspace configured for Oracle Application
Add a new OA Project
Specifi ed the workspace name and project name.

The workspace and project is created but jDev adds all files under JDEV_USER_HOME\ jdev\myprojects which includes all xml, jsp under fnd, icx, ap, pa subdirectories. Then offcourse we are not able to run *PG.xml (e.g. ShoppingHomePG. xml) due to some blank *VO.xml.

Is this the right way of creating project in jDev 10g? OR Should we create empty project and then add content to it? jDev 9i (EBS 11i), never added files by itself, we had to add files (server.xml) to project manually..

Any help will be great!


I am doing following

File -> New
Workspace configured for Oracle Application
Ent er workspace name
Select default directory i.e. USER_JDEV_HOME\ jdev\myprojects
Check "Add new OA project"
Enter project name and directory (same as workspace)
sele ct DB connection and DBC file.

for me all files jsp and xml are getting added under my project. It includes EVERYTHING under fnd, ap, icx, pa (Its a LOT)

Hi Anil,

Thanks a lot...
I have a couple of questions regarding OA Framework customization in R12.
1. Please let me know with the steps to be followed to copy files to/from which locations to go ahead with the customization.
2. For R12, which version of Jdev I should be using.

Great!! ! If you can share some tutorial documents for the same.
Regards,
Satya

Hello Anil

After training on OAF 11i, I finally get to work on R12. I am using the base versionb of R12 on Vision and as a training excercise I am trying to add "approved date" to the iProcurement Self Service Page. Your article is very helpful but I have a question. In the section to extend the view Object you indicate to "create a Business Components package". In 11i , one right-clicks the project and this option appears on the menu. This is not the case in R12. How is this done in R12? In your article - you omit to give the steps on how you did this and I would really like to know how to get past this point.
