Ideally, you must develops and test all your extensions from jDeveloper itself.
This avoids the need for clearing meta-data cache or bouncing the apache or mid-tier

However, you do at times need to test your changes on the server. Generally you will do so when extension is very minor.

When to bounce what, I mean, should we bounce just the Apache or the entire Mid-tier?, for OA Framework changes to take effect.

What is the difference from end-user perspective between apache bounce and mid-tier bounce?
In case of Apache bounce, only the self service[oa framework] sessions will get killed. However in case of entire mid-tier bounce, not only the self service, but also D2K sessions [jInitiator] will be killed.


Usually when we begin development on OAF, in early days we are not sure when to bounce what when deploying your OA Framework developments or extensions to the server.
These are the very basic things one must know, for their OAF changes to take effect after deployment to the server.

  1. Any changes done to files located in $JAVA_TOP requires an apache bounce

           NOTE:- No need to bounce the complete mid-tier

  1. Any changes done to files in MDS Pages will require a full mid-tier bounce. For example, you have customized a OA Framework Page definition [ideally you should need do this, as the same results can be achieved by extension to controller]

  2. When you do personalizations, no bounce is required. This holds true if you have imported the personalizations.

  3. For BC4J substitutions to take effect, you must bounce the complete mid-tier


Here is the table that explains the same

Nature of change

Just Apache Bounce

Complete Mid-Tier bounce

Changes to .class files or xml files that are deployed in $JAVA_TOP

Yes


Changes to Page definitions


Yes

Personalizations done through screen

Not required

Not required

Personalizations imported

Not required

Not required

BC4J Substitutions


Yes

What exactly is apache bounce and mid-tier bounce ?

I am aware of looging in as the 'appl' user in the mid tier
> cd $ADMIN_SCRIPTS_ HOME
>adapcctl. sh stopall
>adapcctl.sh startall

Is this apache bounce or mid-tier bounce ? I have noticed doing this also ends any forms session open.

Thanks,

For Apache bounce, try this ["stop" instead of "stopall"]
$COMMON_TOP/ad min/scripts/$TW O_TASK*/adapcct l.sh stop
$COMMON_TOP/ad min/scripts/$TW O_TASK*/adapcct l.sh start

This will not kill your forms sessions

Thank s,

Anil Sir,

Warm Regards from Me.

Thanks for being a guide for us since quite a long time. We have been referring your site and the articles in it and gaining knowledge from it.

Thanks Again.



Like so many issues which I am being facing, we got a solution for that in your site/Metalink.

I am facing an issue where I would like to enable the Concurrent Request Submission on Self-Service (XML generated by RDF with Word Template or XML generated by PL/SQL stored procedure with word template) for the users. The user will have the opportunity to submit the request without using the Oracle Core Forms. Following are the queries from my end:-

o Is this possible to do? I have tried the same using Oracle Reports (RDF) and succeeded.

o If Yes, How can it be done?

o If No, can you suggest me an alternative solution?



Request your help on this.



Thanks & Regards

Kuber

Hi Kuber

Please dont call me Sir

To run XMLP program, fist call API
FND_REQUEST .SET_PRINT_OPTI ONS

Then call API
FND_REQUEST.SU BMIT_REQUEST


SYntax will be
x_submit_statu s := fnd_request.set _print_options(
printer => l_printer_name,
style => 'YourPrintStyle Here',
copies => 1,
save_output => TRUE,
print_together => 'N');

I think if you call fnd_request.sub mit_request from within a Report, then print options are already found to be set in advance.
The same may not be happening when running the XMLP from Form

Thanks,

Hi Gopik

Please find excerpt from Metalink

You need to download Patch 4573517 from Metalink


Meta link Note:416708.1
S ubject: How to find the correct version of JDeveloper to use with eBusiness Suite 11i or Release 12


Applies to:
Oracle Applications Framework - Version: 11.5.10 to 12.0
Informatio n in this document applies to any platform.
Goal

When you create extensions to eBusiness OA Framework pages, you must use the version of JDeveloper shipped by the eBusiness product team.

The version of JDeveloper is specific to the ATG patch level, so there is a new version of JDeveloper for each release of ATG patchset

This note gives the instruction on how to find right JDeveloper patch for creating OA Extensions with eBusiness Release 11i and Release 12
Solution

To determine which patch to use, you can check the framework version in your instance by using http://host:port/OA_HTML/OAInfo.jsp, then choose the matched JDeveloper patch.
Release 11i
OA Framework 5.10 patch JDeveloper 9i Patch
ATG.PF.H (patch 3438354 or Oracle Applications 11.5.10) Patch 4045639 9IJDEVELOPER WITH OA EXTENSION ARU FOR FWK.H

hi Anil,

I have been a great follower of this site. And thanks to your articles i have been really able to learn good knowledge of OAF. I have just started working on some OAF components. right now i am trying to extend some objects in Iprocurement. what i am trying to do is that i want to add some code in AM and invoke the method from a controller. but while i am trying to extend in jdeveloper , i am not able to see any business component. this i believe is because there is not server.xml file in the server directory for the some component.
so i just want to know how do i get this . i have look up in the server but the server.xml is not present. so i had read sometime ago i have to ask for the server file to oracle. can you please guide me on what to do in this regard? your response would be most appreciated.

Hi Ronel

You are doing the right thing, i.e. extending the AM to add extra methods, and then invoke them via controller extension.
In iProc, a couple of server directories do not have server.xml

You can create server.xml by copying an existing server.xml from other directory.

Nex t, you can edit that as shown below.
NOTE:- You do not need to include all the BC4J objects in server.xml
incl ude only those that you wish to extend.

Thanks
Anil Passi

Hi Anil,

Thank you very much for the server.xml solution you provided.
It Solve the problem of the object extension.
This is the first time i am doing an AM extension but now i am stuck with one problem.

My idea was to extend the AM and as well as at the same time modify one the method in the OLD AM. So is this possible? because this method would allow me to some db transaction with the values i required to. I would be modifying the logic of the method but just to put some extra line of code in the method.
what i am planning to do is copy the old method from the old AM and put it in new AM and modify the method.but i am worried if this is going to work or not?

Please advise me on the same.

Regards,
Rone l

Hi Ronel

It will work, or else what use is of extension.

So, you have two options...
Opti on 1. Your extra logic gets executed after standard logic has been executed?
If so, then
call super.methodFro mOrigAM
execute your custom bits

Option 2. Your extra logic needs to be embedded within the standard functionality
I n this case DO NOT CALL super.methodFro mOrigAM
copy paste the complete original method into extended AM and modify where applicable.
Ple ase be reasonable with your customizations though

In either case, option 1 or option 2, you need to ensure that method in extended AM has exactly the same name and signature as that of method in Original AM

Thanks

Hi Anil,

I have followed the Option 2 for adding logic to old Method in Old AM.

I will give u whole breif of what i have done till now.

1. i hava extended correctItemsAM as xxicxCorrectIte msAM
2. then i have added a custom method execsql() in the newAM
3. i have copied the public boolean correctitems() method from the OLD AM
into the NEW AM and added my code in the correctitems().
4. I then substitute the old AM with the New AM
5. I tried compiling and it's giving a lot compilation errors after i have added the correctitems() method. then i copied the imports from Old AM and put into the new AM . that fixed some of errors but still some compilation errors persist.

Am i missing something in the above steps?

What are the errors? Please elaborate
Quote
0 #13 Ronel T 2008-02-05 17:39
Hi Anil,

the errors are becaused of the some of the variables used are not defined in the new AM.
1. rcvutil.startti meprocedure('') ; rcvutil not found
2. correctvoimpl not found. etc.

this are some infact some of the variables used in the old AMImpl not explicitly defined.

i can't send u the copy the errors as the desktop i m working is not accesible from my system.

Hi All,

I have a OAF page, which shows data in HGrid structure. Hgrid structure is driven using View links.
Now i have added few columns to the page and created a new view link for the HGrid structure. It is working fine in my local instance.
I have deplyed the new set of files and arranged to bounce the middle tier as per the above comments.
Still i am not able to see the tree structure. I guess new view link is not updated there in server.
Could any of you guys please suggest me a solution.

Than ks
Saravan.

I downloaded jdevloper 10.1.3.3 with OAExtension on my local machine. I copied all the java_top files to myclasses. I need to work on oracle.apps.ego product hence i copied only that product files to myprojects, deleted all the class files. Now in jdeveloper i created a project and set the project content to oracle.apps.ego
When I click on any VO, EO or AM that have underlying java files , I get an message that there exist java errors in the .java file located in myprojects.
I do not have any .java files there. Why is this happening, the project compiles fine, i can run a search page but i cannot open any EO, VO or AM objects for viewing.
I need to extend an EO and i get this error message , I am not sure what to do. I reinstalled jdeveloper twice but no use.

Please let me know if you have any ideas. i posted on teh forum but the suggestions did not work.

regards,
