OA Framework Training Tutorials 04 | Print |  E-mail
Written by Anil Passi   
Thursday, 12 July 2007
In this tutorial, we will see how a record in a table can be modified using OA Framework screen.
The video tutorial will be followed by the instructions to deploy these set of Tutorials on Oracle EBS.


Following change will be done to the screen in previous tutorial
1. Add a Link for update to the search result.
This link will fire  an action named updatePerson.
Also, this link will pass a parameter named paramPersonId to the pageContext of Controller Class.
2. When this link is clicked, then processFormRequest(PFR) of the controller will be called in the main page.
3. From the PFR of CO, call another screen named managePersonPG, by retaining the AM.
Note:- this is the same screen that we called for insert/creation functionality in previous tutorial.
4. The navigation now moves to managePersonPG screen, and the Controller method processRequest of managePerson screen will now be called. Note:- Remember that processRequest is called as just prior to the page renders/displays in browser.
5. In processRequest of managePersonPG screen, we will initiate an executeQuery on the viewObject, after setting its where clause.
The result of this action is to make the record being updated to be queried automatically.
6. On managePerson screen, a button named apply changes will be available.
7. After modifying data, user will click apply now, hence invoking processFormRequest.
From processFormRequest, we will call a method in AM, that will commit the transaction.
8. We navigate back to the mainPage i.e. xxPersonMainPG



When a commit takes place, how does OA Framework know whether an insert or update must be done?
When the record being queried is changed by user, that will change the status of the record to dirty.
Hence when commit takes place, Framework will know an update  is required rather than an insert.


What are the steps in tutorial?
1. Create a link for update. In the mainPage's CO, inside PFR, handle the click of update Person.
Call managePerson page, passing it parameter named xxParamPersonId[of record being updated] and xxParamActionOnPerson[=updatePerson, from fireAction property]

2. Set a new controller for this new page
In PR(processRequest) of the managePersonCO, call an AM method to query the PersonId being updated.
Note:-in previous tutorial, we added a button, and program for PFR in new controller, so that commit can be initiated via AM. This commit button is retained as is for this tutorial
3. Redirect back to the original main page, once the commit has taken place
6. Test this

Hi Anil,

I am new to OA Framework.
Once you download the Source code of tutorial 1,2,3,4. how do i open it in Jdeveloper?
Like in Forms D2K, you can ftp any .fmb file and then open in Form Builder.
In the same way do we also have .jws file?

Thanks,
Prashanth

Hi Prashanth

Simply place the files in your myprojects directory.
You can them import the server.xml to open BC4J.
Pages and conrollers can be opened by using File/Open

Thanks,
Anil Passi

i am new to this area.

i have completed all these 4 step tutorial and completed this project. The project is running nicely in Jdeveloper. But when i transfer it to the Oracle apps it started problem. The first page(person details page) is running nicely and the delete function is working but when i go to the update or creation page after update or create and when i press commit it shows oracle.apps.fnd.framework.OAException: No data found for region (gpt/oracle/apps/ak/gpperson/webui/gp2personMainPG)

Exception:
oracle.adf.mds.MetadataDefException: Unable to find component with absolute reference = gpt/oracle/apps/ak/gpperson/webui/gp2personMainPG, XML Path = null. Please verify that the reference is valid and the definition of the component exists either on the File System or in the MDS Repository.


Although the updated data is entered in table but transition to the first page is not happening. I have imported the two xml file to MDS according to your deployment tutorial. I have also tried the import command with includeSubpackages option. please help me in this regard.

Hi Sohail

Please use the jdr utils to check if your document is there in MDS repository

Use this link for jdr_utils http://oracle.anilpassi.com/jdr-utils-2.html


Thanks,
Anil Passi

hi anil,

I am working on oracle apps 11i(11.5.10.2) .The project has lots of extensibility issues, for that we would be using Jdeveloper, for the same i have couple of queries:

1.The version of the jdeveloper which would best suit oracle apps 11i(11.5.10.2).
2.How to decide on the model issue? ( i.e jsp strut bc4j or jsp no strut bc4j etc.)
...
written by Anil Passi , September 25, 2007
Hi Swapnil

Ans 2. No jsp, no struts. Simply use OA Framework

Ans 1.
Pasting the excerpt from my other article, as below......
In your case, it is Patch 4573517
You must not install standalone jDeveloper from http://technet.oracle.com
Download jDeveloper patch from Metalink that comes bundled with OA Framework libraries and wizards

Download one of the below patches. Note that the patch itself will contain either jDev 9i or jDev 10g


Base 11.5.10
Patch 4045639 JDeveloper 9i

11.5.10 ATG CU1
Patch 4141787 JDeveloper 9i

11.5.10 ATG CU2
Patch 4573517 JDeveloper 9i

11.5.10 ATG CU3
Patch 4725670 JDeveloper 9i

11.5.10 ATG CU4
Patch 5455514 JDeveloper 9i

11.5.10 ATG CU5
Patch 6012619 JDeveloper 9i

R12 Base Version
Patch 5856648 jDeveloper 10g

R12 RUP2
Patch 6197418 jDeveloper 10g

Hi Deepak

When Submit Button is clicked, then you can trap that click within ProcessFormRequest of the controller.
From the controller, you can then call a method in AM using invokeMethod

From the AM, you can use JDBC Connection.

For sample code, see below

public void completeWfActivity(Number number)
{
OADBTransactionImpl oadbtransactionimpl = (OADBTransactionImpl)getOADBTransaction();
int i = oadbtransactionimpl.getOrgId();
Number number1 = getOrgId();
try
{
int j = oadbtransactionimpl.getUserId();
int k = oadbtransactionimpl.getResponsibilityId();
int l = oadbtransactionimpl.getResponsibilityApplicationId();
if(number1 != null)
oadbtransactionimpl.setOrgId(number1.intValue());
OIEUtil.setAffValidationContext(oadbtransactionimpl, number1);
String s = "";
s = "BEGIN fnd_wf_engine.CompleteActivity('APEXP',:1,'AP_VERIFY_BLOCK',''); END;";
OracleCallableStatement oraclecallablestatement = (OracleCallableStatement)oadbtransactionimpl.createCallableStatement(s, 1);
try
{
oraclecallablestatement.setObject(1, number);
oraclecallablestatement.execute();
}
catch(Exception _ex) { }
finally
{
try
{
changeResponsibility(j, k, l);
oadbtransactionimpl.setOrgId(i);
OIEUtil.setAffValidationContext(oadbtransactionimpl, new Number(i));
oraclecallablestatement.close();
}
catch(Exception exception2)
{
throw OAException.wrapperException(exception2);
}
}
return;
}
catch(Exception exception)
{
throw OAException.wrapperException(exception);
}
}


Note:- This sample code was nicked from oracle.apps.ap.oie.audit.server.AuditAMImpl.java
